Introduction

The "Current Release page" (referred to herein as the "Precomputed files" page) lists data files generated from the current release of FlyBase and links to the current FTP repository. Data from the previous five releases can be found on the "Archived data files for recent releases" page (referred to herein as the "Archived data" page), as well as links to servers hosting older releases of FlyBase, and all the release notes and news archives from FB2006_01. If you are looking for old data and cannot find it on the "Archived data" page please follow a link to the FTP repository.

Known issues

Safari does not connect properly to the FlyBase FTP site. You should be able to download individual files using Safari but you will not be able to browse the FTP repository.

The FTP archive

The "Main Data Set" section of the "Precomputed files" page provides links to FlyBase FTP repository. The "Chado database" link leads to the psql directory of the current FTP repository where you can obtain a dump of the PostgreSQL Chado database. If you have a PostgreSQL client application installed and would like to access the latest FlyBase release without installing the database you can connect to the FlyBase public read only Chado database as:

$ psql -h chado.flybase.org -U flybase flybase

The version running on this service is identical to the current web site release.

The "Drosophila Data" section contains links to other sections of the FTP repository. The data can be accessed either by the version of FlyBase (The "Current FTP repository") or for sequence data by the annotation release of a particular Drosophila species (see the "Genomes FTP archive")

General information about the available files

File names

The first part of a filename always describes the content of the file, for example the file fbgn_annotation_ID_fb_2008_10.tsv.gz maps the primary FlyBase identifiers to the annotation symbols used for genes.

Many of the precomputed data filenames also contain a release or version number. In the example above "fb_2008_10" denotes version FB2008_10 of FlyBase. Sequence data files, such as dmel-all-CDS-r5.13.fasta.gz, denote the annotation release that the data relates to as '-r5.13'. The 'r5' indicates the data is taken from the release 5 of the sequence assembly and the '13' after the decimal point specifies the annotation release. Please see "A more frequent FlyBase update cycle" for further discussion of the difference between the current release of FlyBase and a genome annotation release.

The following notation is used for different file formats:

Tab separated files are indicated by the extension '.tsv'
OBO format files, which are used for the ontologies, are denoted '.obo'
Plain text files are given the extension '.txt'
Files containing nucleic acid or polypeptide sequence data in the FASTA format are listed as '.fasta'
GFF files include the suffix '.gff'
GTF files include the suffix '.gtf'
XML data files are denoted '.xml'

Most of the files listed on the "Precomputed files" page and the "Archived data" page are compressed with the GNU gzip program. These files end with the suffix '.gz'. The ontology files are compressed in the ZIP file format, as indicated by the suffix '.zip'.


Accessing files

Files can be downloaded either directly through the web interface, or by using an ftp client such as wget to obtain the file from the FTP repository. Please note that at present Safari fails to connect to the FTP repository correctly, so we recommend that you use another browser if you wish to access the files through the web interface. The ftp client wget accepts wild card patterns which means you can use a query of the following kind to obtain the latest file without having to specify the FlyBase release number:

$ wget ftp://ftp.flybase.net/releases/current/precomputed_files/genes/fbgn_annotation_ID_*.tsv.gz

The /releases/current/ path will always point to latest FlyBase release and this directory will have only one copy of the file. Archived copies of the files from previous releases can be obtained by including the FlyBase release in the path /releases/<RELEASE_NUMBER>/. For example to retrieve this file for the FB2008_05 release, type:

$ wget ftp://ftp.flybase.net/releases/FB2008_05/precomputed_files/genes/fbgn_annotation_ID_*.tsv.gz

or more specifically:

$ wget ftp://ftp.flybase.net/releases/FB2008_05/precomputed_files/genes/fbgn_annotation_ID_fb_2008_05.tsv.gz


Opening compressed files

Microsoft and Apple include built-in ZIP support in later versions of their operating systems. These files can also be opened with the free program 7-zip.

On OS X or Unix a GZIP compressed file can be extracted with the gunzip command. On a Windows machine we suggest that you use the program 7-zip to open these files, because several people have reported problems using WinZip. You should be able to open and read the resulting file with any text editor.


Types of files available

XML files

These files are generated from the PostgreSQL Chado database for each release of FlyBase. The Chado XML files contain all the information used to generate the report pages and reflect the organization of the data in the database, whereas the Reporting XML files contain a more compact version of the Chado XML. The DTDs for these XML files, listing the structure of the files, are posted in the chado-xml and reporting-xml directories of the FTP repository for each release. For the latest versions of the DTDs please see:

ftp://ftp.flybase.net/releases/current/chado-xml/

The XML files can also be obtained directly from the "Precomputed files" page by clicking on the "download" link under the ChadoXML heading in the appropriate section. The Chado XML files are available for genes, alleles, stocks, transcripts, polypeptides, insertions, transgenic (recombinant) constructs, aberrations, balancers, clones, and references.

Please note:

The chado_genes.xml.gz file is used to generate the FlyBase gene report pages. Data for the GMOD Common Gene Page project is provided in the chado_common_gene_page.xml.gz file, which is only available as Chado XML from the FTP repository.


Ontology files

The controlled vocabularies (aka ontologies) used by FlyBase are available under the Ontology Terms section of the "Precomputed files" page. Each controlled vocabulary is described in detail in section G.2. of the Reference Manual. The files are in the OBO format used by the Open Biomedical Ontology group, and are designed to be used with the free OBO-Edit tool.

Controlled vocabularies undergo continual development; terms and definitions are refined, added, merged, split and obsoleted in an effort to improve the way they represent their various subjects. On the "Precomputed files" page the frozen versions of the controlled vocabularies used for the current release of FlyBase are available, and there are also links to the current 'live' versions maintained by the Open Biomedical Ontology group.

Frozen versions of the controlled vocabularies used for previous releases of FlyBase are available on the "Archived data" page, and in the following directories of the FTP repository:

ftp://ftp.flybase.net/releases/<RELEASE_NUMBER>/precomputed_files/ontologies/

For example see:

ftp://ftp.flybase.net/releases/FB2008_03/precomputed_files/ontologies/

FASTA files

The FlyBase FASTA files generally follow the FASTA format guidelines with one exception being that our header lines sometime exceed the 80 character limit. The FASTA filenames follow these formats:

dmel-all--r<release-number>.fasta.gz

or

dmel-<chromosome_arm>-<data_type>-r<release-number>.fasta.gz

Where data_type is one of the following entries in the table below. The all files contain sequences for those data types on all chromosome arms whereas the specific chromosome arm have only those features for that particular chromosome.

Data Type Content Description
aligned The region of genomic sequence that analysis features align to.
CDS The contiguous protein coding sequence which begins with, and includes, a start codon and ends with, and includes, a stop codon.
chromosome The sequence of each chromosome arm.
clones The sequence of full length cDNA, 3' and 5' ESTs, and partial length clones.
exon The sequence of each exon split up into individual FASTA records.
five_prime_UTR The sequence of 5' untranslated regions.
gene The sequence of the gene span.
gene_extended2000 The sequence of the gene span with 2000 base pairs added upstream and downstream.
intergenic The sequence of chromosomal regions between genes that do not contain known gene models.
intron The sequence of each intron split up into individual FASTA records.
miRNA The sequence of transcripts that are typed as micro RNAs.

ncRNA The sequence of transcripts that are typed as non coding RNAs (ncRNA).
predicted The sequence of various features that are derived from a variety of prediction algorithms. These can encompass analyses conducted by FlyBase or by 3rd party groups.
pseudogene The sequence of transcripts that are typed as pseudogenes.
sequence_features The sequence of sequence features, which currently describe data about RNAi reagents. In the future, it will also contain natural genomic features (aside from transcribed regions), such as replication origins, transcription factor binding sites and boundary elements, and other experimental reagents that map to the genome, such as microarray oligonucleotides and rescue fragments.
synteny The sequence of syntenic regions between two species.
three_prime_UTR The sequence of 3' untranslated regions.
transcript The sequence of transcripts that are typed as messenger RNAs (mRNA).
translation The resulting protein sequence from protein coding transcripts.
transposon The sequence of transposable elements.
tRNA The sequence of transcripts that are typed as transfer RNAs (tRNA).


FASTA header format

The typical format of our FASTA header begins with an ID followed by any number of fields that follow this format

field_name=value;

Multiple field values are separated by commas

field_name=value1,value2;

This table describes some of the field names found in our FASTA headers

Field Name Description
type The feature type of the FASTA sequence record.
loc The genomic location given in the NCBI's feature location format. Please see the NCBI's site for more information.
ID A unique ID. IDs in the form of FBxx[0-9]+ are a unique FlyBase object identifier.
name The name or symbol of the feature.
dbxref Database cross references relating to the FASTA record. The dbxref values use a 'dbname:dbid' format.
MD5 An MD5 checksum calculated from the sequence that can be used to identify identical sequences.
length The length of the sequence found in the FASTA record.
release The release number denotes the annotation release which this FASTA record corresponds to.
species The species abbreviation that this FASTA record corresponds to.


GFF files

The FlyBase GFF files follow the GFF v3 specification. The GFF files contain feature line definitions for gene models, predicted features, alignments, and many other features. The GFF files are produced for each species and can be downloaded from our FTP site using this URL form:

ftp://ftp.flybase.org/genomes/<species abbreviation>/current/gff/

e.g. ftp://ftp.flybase.org/genomes/dmel/current/gff/

For melanogaster, there are 3 GFF files distributed, they include:

dmel-all-r<release-number>.gff.gz
Contains all chromosome arms
dmel-all-no-analysis-r<release-number>.gff.gz
Same as above except all match and match_part features have been removed
dmel-<chromosome_arm>-r<release-number>.gff.gz
Contains only a single chromosome arm as identifed by the filename

The other species have the all chromosome arm file and also a tar and gzipped file containing the individual scaffolds. Please note that the tarball contains thousands of files in a single directory level so extracting them may result in filesystem performance issues.

GTF files

The FlyBase GTF files follow the GTF v2.2 specification. The GTF files contain feature line definitions for gene models. The GTF are produced for each species and can be downloaded from our FTP site using this URL form:

ftp://ftp.flybase.org/genomes/<species abbreviation>/current/gtf/

e.g. ftp://ftp.flybase.org/genomes/dmel/current/gtf/

Precomputed data text files

Precomputed data files that contain useful sets of data are generated for every release of FlyBase. For example, the file fbgn_NAseq_Uniprot_fb_2008_10.tsv.gz contains the mapping between valid FlyBase identifiers and the corresponding nucleic acid and protein accession numbers used by DDBJ/EMBL/GenBank and UniprotKB/Swiss-Prot/TrEMBL. These files can be found under the "Other" heading of each section of the "Precomputed files" and "Archived data" pages, and are also available under the precomputed_files directory of each FlyBase release in the FTP repository.

Superscripts and subscripts are represented in the precomputed data files in the ASCII text format used by FlyBase, which is described in section 10.3 of the Nomenclature document.

At the top and bottom of each tab separated text file there are a few lines that describe the file. These lines start with a '#' symbol. The line immediately before the start of the data contains headings for each of the tab separated columns in the file. The file can also include some blank lines to separate information about the version of the file from the description of data in the file.

Each precomputed data file available for download on the "Precomputed files" page contains the complete data set for the FlyBase release. Please note, if you are only looking for information on a defined subset of genes, or other FlyBase data type, you can query the current set of precomputed data files through the Batch Download tool to obtain the data you require. This approach is described in more detail in the "How to Download Field Data" section of the help document at the bottom of the Batch Download page.

Genes

Genes data (Chado XML or Reporting XML)

Genetic interaction table (gene_genetic_interactions_*.tsv)

The file reports the summary of gene-level genetic interactions in FlyBase. This data is computed from the allele-level genetic interaction data captured by FlyBase curators.

The file includes information for Dmel genes only.

Interactions involving any of the following kinds of allele are considered when the gene-level genetic interaction data is computed:

  • classical mutations
  • alleles carried on transgenic constructs
  • loss-of-function mutations
  • gain-of-function mutations

File format:

Column heading Content Description
Starting_gene(s)_symbol Current FlyBase symbol of gene(s) involved in the starting genotype.
Starting_gene(s)_FBgn Current FlyBase identifier (FBgn#) of gene(s) involved in the starting genotype.
Interacting_gene(s)_symbol Current FlyBase symbol of gene(s) involved in the interacting genotype.
Interacting_gene(s)_FBgn Current FlyBase identifier (FBgn#) of gene(s) involved in the interacting genotype.
Interaction_type Type of interaction observed, either 'suppressible' or 'enhanceable'.
Publication_FBrf Current FlyBase identifier (FBrf#) of publication from which the data came.


Notes:

  • Each row contains information from a single reference. Thus if the same genetic interaction has been reported in multiple references, multiple rows will exist for that genetic interaction in the file.
  • 'suppressible' in column 5 indicates that phenotypes caused by mutation of the gene(s) listed in the starting genotype (column 1) are suppressed by mutation of the gene(s) listed in the interacting genotype (column 3).
  • 'enhanceable' in column 5 indicates that phenotypes caused by mutation of the gene(s) listed in the starting genotype (column 1) are enhanced by mutation of the gene(s) listed in the interacting genotype (column 3).

e.g.

Pten FBgn0026379 Akt1 FBgn0010379 suppressible FBrf0127089

indicates that phenotype(s) caused by a mutation of Pten are suppressed by a mutation of Akt1.

  • For cases where multiple genes are simultaneously mutated in either (or both) the starting and interacting genotype, then the genes involved are separated by a '|' in the relevant columns. In this case, the order of the list of symbols and of the list of ids in columns 1 and 2, or in columns 3 and 4 respectively are the same, so that the FBgn corresponding to the symbol for each gene can easily be identified.

e.g.

robo1|sli FBgn0005631|FBgn0264089 RhoGAP93B FBgn0038853 enhanceable FBrf0191476

indicates that:

  • phenotype(s) caused by a robo1, sli double mutant combination are enhanced by a mutation of RhoGAP93B.
  • FBgn0005631 corresponds to robo1, FBgn0264089 corresponds to sli


RNA-Seq RPKM values (gene_rpkm_report_fb_*.tsv.gz)

This file reports gene expression values based on RNA-Seq experiments, calculated as reads per kilobase per million reads (RPKM). RPKM values are calculated only for the unique exonic regions of the gene (excluding segments that overlap other genes), except for genes derived from dicistronic/polycistronic transcripts, in which case all exon regions are used in the RPKM expression calculation.

Functional complementation table (gene_functional_complementation_*.tsv)

This file reports when functional complementation of Dmel genes by non-Dmel orthologs has been observed. This data is computed by FlyBase using a combination of the orthology data obtained from DIOPT and OrthoDB and the allele-level genetic interaction data curated from the literature. The file contains a list of gene Dmel - to - non-Dmel-ortholog gene pairs where a transgenic construct/mutant allele of the non-Dmel ortholog has been shown to at least partially suppress mutant phenotype(s) of an allele of the Dmel gene.

File format:

Column number Column heading Content Description
1 Dmel gene (symbol) Current FlyBase symbol of Dmel gene.
2 Dmel gene (FBgn) Current FlyBase identifier (FBgn#) of Dmel gene in column 1.
3 Functionally complementing ortholog (symbol) Current FlyBase symbol of a non-Dmel ortholog of the Dmel gene in column 1 where this non-Dmel gene has been show to functionally complement the Dmel gene.
4 Functionally complementing ortholog (FBgn#) Current FlyBase identifier (FBgn#) of a non-Dmel ortholog of the Dmel gene in column 1 where this non-Dmel gene has been show to functionally complement the Dmel gene.
5 Supporting_FBrf Current FlyBase identifier (FBrf#) of the publication that provides support for the functional complementation statement (the publication that reported the suppression of a mutant phenotype of the Dmel gene by a transgenic construct/mutant allele of the non-Dmel ortholog).

Notes:

  • Each row contains information from a single reference. Thus if multiple references support the same functional complementation statement, multiple rows will exist for that statement in the file.


FBgn <=> DB Accession IDs (fbgn_NAseq_Uniprot_*.tsv)

The file reports EMBL/GenBank/DDBJ nucleotide and protein accessions, UniProtKB/SwissProt/TrEMBL protein accessions, NCBI Entrez gene IDs and NCBI RefSeq transcript and protein accessions associated with FlyBase genes.

The file includes:

  • nuclear genes with sequence accession numbers
  • mitochondrial genes

it excludes:

  • genes without sequence accession numbers

File format:

Column number Column heading Content Description
1 gene_symbol Current symbol of gene.
2 organism_abbreviation Abbreviation (from the Species Abbreviations list) indicating the species of origin of the gene.

8 RefSeq_transcripts NCBI RefSeq transcript accession associated with the gene.
9 RefSeq_proteins NCBI RefSeq protein accession associated with the gene and the transcript accession in the preceeding 'RefSeq_transcripts' column.

Notes:

  • Each row contains information about a single accession associated with a gene, thus if a gene has multiple accessions associated with it, multiple rows will exist for that gene in the file.
  • A single row contains only information about an EMBL/GenBank/DDBJ accession or information about a UniProtKB/SwissProt/TrEMBL accession or an NCBI Entrez gene ID or an NCBI RefSeq transcript accession.
  • For rows containing information about a EMBL/GenBank/DDBJ accession, a nucleotide accession associated with the gene is listed in column 4 ('nucleotide_accession'). If there is also a EMBL/GenBank/DDBJ protein accession associated with that gene and with the nucleotide accession in column 4, this protein accession is listed in column 5 ('na_based_protein_accession'). In this case, columns 6, 7, 8 and 9 are always empty.
  • For rows containing information about a UniProtKB/SwissProt/TrEMBL protein accession, a protein accession associated with the gene is listed in column 6 ('UniprotKB/Swiss-Prot/TrEMBL_accession'). In this case, columns 4, 5, 7, 8 and 9 are always empty.

Notes:

  • Each row contains information about a single transcript and the polypeptide it encodes (if relevant). Thus if a gene encodes multiple isoforms, multiple rows with exist for that gene in the file.


FBgn exons <=> Affy1 (fbgn_exons2affy1_overlaps.tsv)

The file is generated by testing for overlaps, no matter how small, of the locations of Affy1 oligos in the genome with the locations of gene exons, as defined by the Dmel gene models for the current release of FlyBase. If the location of an Affy1 oligo shows any kind of overlap with an exon of a gene, a Gene=>Affy reference is recorded in this file.

The extent of the overlap has no influence on the inclusion of a crossreference in this file. The overlap might be just one nucleotide, or it could be an exact match to the exon. For interpretation of the significance of a partial overlap please contact Affymetrix.

The file includes the following Dmel genes:

  • nuclear genes located to the sequence

it excludes:

  • genes not located to the sequence
  • mitochondrial genes

Notes:

  • Each line of the file can contain many tab separated columns:
  • The first column of a line contains the valid FlyBase identifiers of a gene.
  • Subsequent columns: Each Affy1 ID that overlaps with an exon of the gene, as described above, is listed in an additional tab separated column. Thus, this file does not contain a predefined number of columns.

This is identical to the file of the same name listed under the 'Orthologs' section above.


Nomenclature

Species abbreviation list (species-ab.gz)

The species-abbreviations.txt file lists all the species for which FlyBase has some information. FlyBase includes gene reports for genes derived from species within the family Drosophilidae, as well as gene reports for non-drosophilid genes ("foreign genes") that have been introduced into Drosophila via transgenic constructs and for engineered objects such as a fusion gene between two D.melanogaster genes. In addition, information about non-Drosophilid species is also displayed in GBrowse, for example in the "Similarity: Proteins" evidence tier. Thus, the file contains information for both Drosophilid and non-Drosophilid species.

There are 8 columns of data in the file, each separated by " | ".

Column heading Content Description
Internal_id The Primary FlyBase identifier of the organism.
Taxgroup A grouping term, currently one of "drosophilid", "non-drosophilid eukaryote", "prokaryote", "transposable element" or "virus".
Abbreviation The standard FlyBase prefix for the species. This abbreviation is used in FlyBase as the first part of the symbol (before the '\') of any object, e.g. a gene or allele, that originates from this species. This column may be blank, if data from a species is displayed in an evidence tier on GBrowse but no individual report page exists for that species in FlyBase.

Map conversion tables

Cytological <=> Sequence (genome-cyto-seq.txt)

This is a tab delimited file that FlyBase uses to relate sequence coordinates from release 5 of the Drosophila melanogaster sequence assembly to published cytogenetic map positions. A description of how this is calculated is provided in section G.5.1. of the Reference manual.

The data for each chromosome arm is separated by a line starting with a '#' that lists the name of the chromosome arm and corresponding sequence scaffold.

The columns in the file are:

Column heading Content Description
- Cytogenetic map position as described by Bridges.
- First sequence coordinate for this map position in the sequence scaffold corresponding this chromosome arm.
- Last sequence coordinate for this map position in the sequence scaffold corresponding this chromosome arm.


Cytological <=> Genetic (cytotable.txt)

This is the table that FlyBase uses to infer a genetic map position from a published cytogenetic map position for Drosophila melanogaster.

The first six lines of the file describe the contents of the file or are blank. The data in the file is organized with the cytological position in first four characters of a line followed by a run of spaces and then the genetic map position.


Cyto <=> Genetic <=> Seq (cyto-genetic-seq.tsv)

This is a tab separated file generated from the cytotable.txt and genome-cyto-seq.txt files that infers the relationship between published cytogenetic map positions, genetic map positions and release 6 sequence assembly coordinates for Drosophila melanogaster. Please note that band numbers are not given in this file because they are absent in cytotable.txt.

File format:

Column heading Content Description
Cytogenetic map position Cytogenetic map position.
Genetic map position Genetic map position.
Sequence coordinates (release 6) Sequence coordinates (release 6) for the interval.
