Hi, I have a gff3 file wtih info: CDS exon intron and parent genes.

I am interesting to define 5' and 3' UTR regions. I can use bedtools subtract to get the UTR regions but I am not sure if I am in the right way since I can not take into consideration the orientation of the genes and I am not able to define 5' or 3' UTRs

If you have any other alternative solution I would highly appreciate it.

thank you all for your help!

So far I have used: awk '/exon/ {print $0}' all_maker_genes.gff > all_genes_exons.gff and awk '/CDS/ {print $0}' all_maker_genes.gff > all_genes_CDS.gff followed by

bedtools subtract -a all_genes_exons.gff -b all_genes_CDS.gff > UTR_regions.gff

utr next-gen gff3 genome • 1.4k views

In one of the rare cases where the gff3 is perfect. I typically use gff3ToGenePred utility (available here http://hgdownload.cse.ucsc.edu/admin/exe/linux.x86_64/ ) to convert gff3 to GenePred format and the use another utility genePredToBed (also available there) to convert to bed. After that it is much easy to get specific regions. But success has been rare and dependent on how perfect is the gff3 formatted.

Hi I have tried the approach, although I am setting -maxParseErrors=-1 -maxConvertErrors=-1 which is what they say at the manual to avoid errors I still get errors and my job is never done...

Any help will be great!

thanks

Sorry that I am avoiding parsing the gff3 file. I presume that the genome is Leersia Perrieri and the gff3 file is from ensemble. You could try ensemble plants -> biomart -> Leersia Perri Then select attributes -> sequences from the left hand side menu -> Select 5' UTR or 3' UTR -> in the header select 5' UTR start and end . The resulting fasta header will contain the coordinates of the UTRs and they can be parsed out.

ADD REPLYlink written 2.5 years ago by microfuge970

I have already tried that but it does not really work since not so many UTR regions are annotated. On top of that I have some more species that I need to do it

ADD REPLYlink written 2.5 years ago by Chris30

In not very well studied plants that is a very usual case. Not many UTRs are known, even if you have a bed file. The transcription start and end would be same as cds start and end thereby no UTRs are annotated.

The canon-gff3 tool from the AEGeAn Toolkit will infer UTRs (and start/stop codons) from gene structures such as those you describe.
