Have you looked at the contents of your provided GTF file? With the -g option on featureCounts you're telling it to look for the identifier you proided. Most likely your GTF file is either missing the identifier you provided or is using a different name.

I see the "gene_id" is present. I also converted the .gtf file into an excel table also and the 9th column is indeed "gene_id". Each column of the .gtf file has 335791 entries.

I seem to be having the same issue with a .gtf file downloaded from NCBI: GCF_003339765.1_Mmul_10_genomic.gtf

I am aware from this guidance (https://mblab.wustl.edu/GTF2.html) and this biostars question (GFF3 to GTF conversion - 9th column) that gene_id and transcript_id must be at the start of the 9th column and I tried to correct my .gtf file based on recommendations in the biostar post, however, this hasn't solved the issue.

I have another annotation downloaded from Ensembl and it runs fine however it's not the annotation I want to use.

Further clarification on this would be greatly appreciated and thank you for you time reading this

I was having the same error message. I tried to manipulate my gtf file in many ways. I read someone suggesting to go to an older version of subread and that worked for me. We happened to have subread/1.5.1. Good luck.

You can try AGAT it might fix your problem

featureCounts does not allow empty values in the gene_id field, so you need to remove or update them. See this answer from the developer https://groups.google.com/g/subread/c/xs7mw38Bc6g.

grep 'gene_id ""' GCF_003254395.2_Amel_HAv3.1_genomic.gtf 
grep -v 'gene_id ""' GCF_003254395.2_Amel_HAv3.1_genomic.gtf > Amel_HAv3.1_FIXED.gtf

Thanks, Chris S. It seemed to work for me. Since I am not well versed with grep, please kindly tell me (us) how did you fix the GTF file? And where from could we learn more about handling this type of issues. Thanks a lot.

To anyone finding this thread after getting a related "gene_id" error in featureCounts or subread-align, I had this same issue but it was not resolved by clearing empty values following "gene_id" field in column nine (my gtf did not have empty values).

I was, however, able to resolve the issue and get subread to function (subread-align) by removing "exon_number" fields from column 9 that were present in addition to "transcript_id" and "gene_id". So if you're like me and still trying to get your .gtf to play nicely with subread, I'd suggest looking for anything in column 9 that isn't transcript_id or gene_id, then removing it.

THANK YOU. This is the only thing that worked for me. for anyone else who may need it, I used the command

sed 's/\(gene_id "[^"]*\).*/\1"/' original_annotation.gtf > fixed_new_annotation.gtf

to remove everything that followed the the gene id and now feature counts runs for me.

I confirm that this fixed the issue also for me. Remove everything besides gene_id and transcript_id

The best way for me was converting the file into SAF format http://bioinf.wehi.edu.au/featureCounts/

GeneID  Chr Start   End Strand
497097  chr1    3204563 3207049 -
497097  chr1    3411783 3411982 +
497097  chr1    3660633 3661579 -
..

after two days of struggle to solve this I found that it was happening because 9th column didn't had "GeneID" word in the geneid section. it is very particular about the word and format

I converted the file into SAF format and hurray!! it ran perfectly. I converted to reflect only gene features, you can use according to your requirement.

grep 'gene' annot.gff |cut -d ';' -f1|tr -d ' ' |sed 's/ID=//g'|awk -v OFS='\t ''{print $9,$1,$4,$5,$7}' >annot.gff.SAF
featureCounts -T 20 -F SAF -a annot.gff.SAF -o FeatureCounts.out 1.bam 2.bam

Edit: Problem solved: RNA-seq - Creating SAF from NCBI gff for Subread featureCounts - keep 'gene' or 'exon'

I just ran into this issue, and I think the answer by onkar is the one that most helps understanding the underlying problem. According to subread featureCounts documentation, the annotation file should be either GTF (not NCBI GFF!!) or SAF (same as example provided by onkar )

The expected 9th column GTF format is as follows:

gene_id "Em:U62317.C22.6.mRNA"; transcript_id "Em:U62317.C22.6.mRNA"; exon_number 1

It seems featureCounts accepts only either:

a) GTF: column 9 contains 'gene_id' ANYWHERE in the column (not just at the start). The following example column 9 format from biostars RNA-seq by example works fine:

  • gene_name=AAA-750000-UP-4; gene_id=AAA-750000-UP-4; transcript_id=AAA-750000-UP-4-T; exon_number=1;

b) SAF: column 1 is GeneID

Clearly column 9 from my NCBI GFF was never going to work:

ID=geneLOC100125545;Dbxref=GeneID:100125545;Name=LOC100125545;gbkey=Gene;gene=LOC100125545;gene_biotype=protein_coding

Other possible solutions:

a) Provide the featureCount option -g to explicitly tell featureCounts to look for "Dbxref=GeneID:" instead of "gene_id". I don't know if some variation of that will work but if it does, it means not having to create a complex one-off fix to parse an NCBI GFF, which is just a nuisance. (edit: tried -g Dbxref which got the program to run, but the counts.txt ouput needs alot of parsing)

b) Just get the annotation GTF from Ensembl which has the required format as suggested by @hannepainter. (edit: best option)
