It has the power to check, fix, pad missing information (features/attributes) of any kind of gtf and gff to create complete, sorted and standardised gff3 format.
The GTF/GFF formats are 9-column text formats used to describe and represent genomic features.
The formats have quite evolved since 1997, and despite well-defined specifications existing nowadays they have a great flexibility allowing holding wide variety of information.
This flexibility has a drawback aspect, there is an incredible amount of flavour of the formats, that can result in problems when using downstream programs.
For a complete overview of the formats have a look at this page.
Some examples what AGAT can do:
-
standardise any GTF/GFF file into a comprehensive GFF3 format (script with
agat_spprefix):- add missing parent features (e.g. gene and mRNA if only CDS/exon exist).
- add missing features (e.g. exon and UTR).
- add missing mandatory attributes (i.e. ID, Parent).
- fix identifier to be uniq.
- fix feature location.
- remove duplicated features.
- group related features (if spread in different places in the file).
- sort features.
- merge overlapping loci into one single locus (only if option activated).
-

As AGAT is a toolkit, it contains a lot of tools. The main one is agat_convert_sp_gxf2gxf.pl that allows to check, fix, pad missing information (features/attributes) of any kind of gtf and gff to create complete, sorted and standardised gff3 format.
All the installed scripts have the agat_ prefix.
Typing agat_ in your terminal followed by the key to activate the autocompletion will display the complete list of available tool installed.
The gff file will be charged in memory Omniscient data structure that is way to facilitate access to desired features at any time. It has a memory cost but make life smoother. Indeed, it allows to perform complicated tasks in a more time efficient way. Moreover, it allows to fix all potential errors in the limit of the possibilities given by the format itself. See the Omniscient section for more information about it.
The gff file is read and processed from its top to the end line by line without sanity check. This is memory efficient.
All tools with agat_sp_ prefix will parse and slurps the entire data into a data structure called Omniscient.
Below you will find more information about peculiarity of the Omniscient structure,
and the parsing approach used.
The method create a hash structure containing all the data in memory. We call it OMNISCIENT. The OMNISCIENT structure is a three levels structure:
$omniscient{level1}{tag_l1}{level1_id} = feature <= tag could be gene, match
$omniscient{level2}{tag_l2}{idY} = @featureListL2 <= tag could be mRNA,rRNA,tRNA,etc. idY is a level1_id (know as Parent attribute within the level2 feature). The @featureList is a list to be able to manage isoform cases.
$omniscient{level3}{tag_l3}{idZ} = @featureListL3 <= tag could be exon,cds,utr3,utr5,etc. idZ is the ID of a level2 feature (know as Parent attribute within the level3 feature). The @featureList is a list to be able to put all the feature of a same tag together.
The Omniscient parser phylosophy:
-
- Parse by Parent/child relationship
-
- ELSE Parse by a common tag (an attribute value shared by feature that must be grouped together. By default we are using locus_tag but can be set by parameter).
-
- ELSE Parse sequentially (mean group features in a bucket, and the bucket change at each level2 feature, and bucket are join in a common tag at each new L1 feature).
/!\ Case with only level3 features (i.e rast or some prokka files, sequential will not work as expected. Indeed all features will be the child of only one newly created Parent. To create a parent per feature or group of feature, a common tag must be used to group them correctly. We use gene_id and locus_tag by default but you can set up the one of your choice)
To resume by priority of way to parse: Parent/child relationship > locus_tag > sequential.
The parser may used only one or a mix of these approaches according of the peculiarity of the gtf/gff file you provide.
=> It creates missing parental features. (e.g if a level2 or level3 feature do not have parental feature(s) we create the missing level2 and/or level1 feature(s)).
=> It creates missing mandatory attributes (ID and/or Parent).
=> It fixes identifier to be uniq.
=> It removes duplicated features (same position, same ID, same Parent).
=> It expands level3 features sharing multiple parents (e.g if one exon has list of multiple parent mRNA in its Parent attribute, one exon per parent with uniq ID will be created.
=> It fixes feature location errors (e.g an mRNA spanning over its gene location, we fix the gene location).
=> It adds UTR if possible (CDS and exon present).
=> It add exon if possible (CDS has to be present).
=> It group features together (if related features are spread at different place in the file).
AGAT has been tested on 32 different peculiar GTF/GFF formats being different flavours or/and containing errors.
Below few are listed but you can find the full list of them into the t/gff_syntax directory.
