Genes in gtf or gff format

GTF Downloads Directory

• There are pre-made GTF format files for every assembly that has knownGene, ncbiRefSeq, refGene, and Ensembl data.
• These can be found at the following download server address:

  http://hgdownload.soe.ucsc.edu/goldenPath/$db/bigZips/genes/ 

  where $db is the assembly of interest.
• For example, the hg38 GTF files: http://hgdownload.soe.ucsc.edu/goldenPath/hg38/bigZips/genes/

Summary of limitations for Table Browser GTF output

• The Table Browser has transcript IDs only, so although it includes both "gene_id" and "transcript_id" fields in its output, the value for transcript ID (e.g., ENST#) is used for both fields.
• The Table Browser adds start and stop codon annotations whether or not the transcript alignment includes proper start and stop codons.
• Some tables in older genome assemblies are not supported.
• Tables not in genePred format (e.g., knownCanonical) will produce unexpected GTF output, in addition to the other "known-limitations for Table Browser GTF output" listed here.
• Issue with stop codons in GTF output from Table Browser

Warning - using a non genePred table to get GTF output in the Table Browser

A genePred table (such as knownGene) is needed to get GTF output in the Table Browser. Below is an example of output for the knownCanonical table, which is NOT in genePred format. Even though the TB GTF says "exons" for knownCanonical GTF output, it's really just a placeholder, not exons at all, but rather start-stop regions of the transcripts.

For example, if you do a cart reset (top menu > Genome Browser > Reset All User Settings) and go to the default region (chr1:11102837-11267747) in hg38, then go to the Table Browser, and then get all fields for knownCanonical (limit to default region, not genome), you'll get this output:

#chrom	chromStart	chromEnd	clusterId	transcript	protein

Note that the GTF regions are not exon regions, they are start-stop regions. Note also that GTF is 1-based, unlike 0-based "all fields" output. See the coordinate blog for more information about 0-based vs 1-based coord systems.

Convert genePred to GTF with the genePredToGtf command line utility

GenePred is a table format commonly used for gene prediction tracks in the UCSC Genome Browser. The genePredToGtf command-line utility can be used to convert genePred to GTF.

While the Table Browser does contain an option to output query results in GTF, the output is limited, and in some cases, may contain bugs. The best method to convert genePred to GTF is the genePredToGtf command-line utility. The operating-specific utility can be downloaded from the utilities directory.

Once downloaded (and permissions changed to executable), you can run the utility without arguments to see the usage statement:

$ genePredToGtf
genePredToGtf - Convert genePred table or file to gtf.
usage:
   genePredToGtf database genePredTable output.gtf
If database is 'file' then track is interpreted as a file
rather than a table in database.
options:
   -utr - Add 5UTR and 3UTR features
   -honorCdsStat - use cdsStartStat/cdsEndStat when defining start/end
    codon records
   -source=src set source name to use
   -addComments - Add comments before each set of transcript records.
    allows for easier visual inspection
Note: use a refFlat table or extended genePred table or file to include
the gene_name attribute in the output.  This will not work with a refFlat
table dump file. If you are using a genePred file that starts with a numeric
bin column, drop it using the UNIX cut command:
    cut -f 2- in.gp | genePredToGtf file stdin out.gp

Using Table Browser output as input for the genePredToGtf

You can use Table Browser output as input for the genePredToGtf utility, but you will need to check that the Table Browser output is indeed in the correct GenPred format. In some cases, you may have trailing columns that need to be removed.

For example,

1. From the UCSC Genome Browser, click on "Genome Browser" at the top menu bar, then select "Reset All User Settings" to refresh to the default hg38 assembly and its default position.
2. Go to the Table Browser, and keeping all options as default, change only 1 setting: region should be set to "position" instead of genome.
3. Accept the default drop-down option for "output format" as "all fields from selected table" and
4. Type in a name for "output file" to download your file (e.g., "knownGeneABO.txt").
5. Click "get output."

Note that you will have 12 columns; and you will need to remove the last two columns to get genePred format:

cat knownGeneABO.txt | cut -f1-10 > knownGeneABO.genePred

Now convert to GTF, using the "file" argument for genePredToGTF:

genePredToGtf file knownGeneABO.genePred knownGeneABO.gtf

Use genePredToGtf with a downloaded genePred table

You can directly download a table (for example, the knownGene table), which will be in genePred format. You can then use this local file as input for the genePredToGtf conversion.

ftp://hgdownload.soe.ucsc.edu/goldenPath/hg19/database/knownGene.txt.gz

The SQL structure:

ftp://hgdownload.soe.ucsc.edu/goldenPath/hg19/database/knownGene.sql

As noted in the usage message, the file can be used with the command in place of the database table specification. In this case, beware of files that are only partially genePred format. For example, the knownGene.txt.gz file has extra columns after the exonEnds column. Therefore, use cut to extract just the columns for genePred:

$ zcat knownGene.txt.gz | cut -f1-10 | genePredToGtf file stdin knownGene.gtf

Example with downloaded refGene.txt.gz

Here are detailed steps for converting a local hg19 refGene table (in genePred format) to GTF.

1. Download your gene set of interest for hg19. For this example, I'll use the refGene table, but you can choose other gene sets, such as the knownGene table from the "UCSC Genes" track.

rsync -a -P rsync://hgdownload.soe.ucsc.edu/goldenPath/hg19/database/refGene.txt.gz ./

2. Unzip

gzip -d refGene.txt.gz

3. Remove the first "bin" column:

cut -f 2- refGene.txt > refGene.input

4. Convert to gtf:

genePredToGtf file refGene.input hg19refGene.gtf

5. Sort output by chromosome and coordinate

cat hg19refGene.gtf  | sort -k1,1 -k4,4n > hg19refGene.gtf.sorted

Example output for hg19refGene.gtf.sorted:

$head hg19refGene.gtf.sorted

Using kent commands with the public database server

To use the kent commands with the public database server, add this four line file ".hg.conf" to your home directory. One way is to use the echo command and the >> to append lines into .hg.conf:

echo db.host=genome-mysql.soe.ucsc.edu >> .hg.conf
echo db.user=genomep >> .hg.conf
echo db.password=password >> .hg.conf
echo central.db=hgcentral >> .hg.conf

Check your work with the following command:

cat $HOME/.hg.conf

Download GenePredToGtf utility from the command line:

#for MacOSX
wget http://hgdownload.soe.ucsc.edu/admin/exe/macOSX.x86_64/genePredToGtf
#for Linux
wget http://hgdownload.soe.ucsc.edu/admin/exe/linux.x86_64/genePredToGtf

Set the permissions:

 chmod 600 .hg.conf
 chmod +x genePredToGtf

Now you can use the genePredToGtf command to pull gene files directly from the UCSC public database and convert them to GTF format. For example, fetch NCBI's refGene track from hg38 and save to a local file named refGene.gtf:

 ./genePredToGtf hg38 refGene refGene.gtf

Note: The GTF files in the UCSC download server were created using the -utr flag. This adds the 5' and 3' utrs to the 9th field:

 ./genePredToGtf -utr hg38 refGene refGene.gtf

Bed format gene tracks (convert bed > genePred > GTF)

Some gene tracks are in a bed format in the database, perhaps with extra columns past the standard bed format. In this case, extract the standard bed columns, convert it to a genePred and then to a gtf. For example wgRna:

mysql --user=genome --host=genome-mysql.soe.ucsc.edu -A -N \
  -e "select chrom,chromStart,chromEnd,name,score,strand,thickStart,thickEnd from wgRna;" hg19 \
   | bedToGenePred stdin stdout | genePredToGtf file wgRna.gtf

Note that in the above methods, it was necessary to cut columns 1 - 10 to remove the extra trailing columns. With the method detailed here, this cut is not necessary in the case of using the database table since the command can determine from the table structure which columns to use.

Get a genePred file from UCSC MySQL public databases, then convert to GTF

Information about MySQl - http://genome.ucsc.edu/goldenPath/help/mysql.html

MySQL query example to get a genePred file:

$ mysql --host=genome-mysql.soe.ucsc.edu --user=genome -Ne "select a.name, a.chrom, a.strand, a.txStart, a.txEnd,\
a.cdsStart, a.cdsEnd, a.exonCount, a.exonStarts, a.exonEnds, 0 as score, b.geneSymbol from knownGene a join \
kgXref b on a.name=b.kgID" hg19 > hg19.genePred

Next, using the genePredToGtf utility:

genePredToGtf file hg38.genePred hg38.knownGene.gtf

genePred output will look like this:

uc001aaa.3    chr1    +    11873    14409    11873    11873    3    11873,12612,13220,    12227,12721,14409,    0    DDX11L1

For a full list of options available to gtfToGenePred, run the program with no args:

gtfToGenePred - convert a GTF file to a genePred
usage:
   gtfToGenePred gtf genePred

options:
     -genePredExt - create a extended genePred, including frame
      information and gene name
     -allErrors - skip groups with errors rather than aborting.
      Useful for getting infomation about as many errors as possible.
     -ignoreGroupsWithoutExons - skip groups contain no exons rather than
      generate an error.
     -infoOut=file - write a file with information on each transcript
     -sourcePrefix=pre - only process entries where the source name has the
      specified prefix.  May be repeated.
     -impliedStopAfterCds - implied stop codon in after CDS
     -simple    - just check column validity, not hierarchy, resulting genePred may be damaged
     -geneNameAsName2 - if specified, use gene_name for the name2 field
      instead of gene_id.
     -includeVersion - it gene_version and/or transcript_version attributes exist, include the version
      in the corresponding identifiers.
