Hello, If the datatype is really just GFF, it would not contain key attributes that a GTF does, so it can't be used. But I suspect the data is really GTF or GFF3, as actual GFF is a much older format specification and not used much anymore.... As the warning indicates, the GFF version is 3, not 2, meaning that it is not a GTF file, but a GFF3 file, which agrees with the file extension, so you probably shouldn't pass "gtf" as the format.

AWK GTF! How to Analyze a Transcriptome Like a Pro Part

Make sure to use a splicing-aware aligner such as STAR. HTSeq-count makes full use of the information in the CIGAR field. I have used a GTF file generated by the Table Browser function of the UCSC Genome Browser, and most reads are counted as ambiguous. Why? In these files, the gene_id attribute incorrectly contains the same value as the transcript_id attribute and hence a different value...

How To Make A Gtf File

The file genome.fa in this example would be a multi fasta file with the genomic sequences of the target genome. This also requires that every contig or chromosome name found in the 1st column of the input GFF file (transcript.gtf in this example) must have a corresponding sequence entry in chromosomes.fa. This should be the case in our example if genome.fa is the file corresponding to the same
