Please help to figure out how to fix the following error:
Fatal INPUT FILE error, no valid exon lines in the GTF file: /galaxy-repl/main/files/021/715
I've made fastQ file from Ion Torrent unmapped RNA bam by using samtools bamtofastq and running the file on (RNA-STAR) in Galaxy.
I've downloaded Homo_sapiens.GRCh37.75.gtf from tp://ftp.ensembl.org/pub/ and ran the job.
I got an error message several minutes after starting the job: "Fatal INPUT FILE error, no valid exon lines in the GTF file: /galaxy-repl/main/files/021/715"
I did see a post about removing/changing "chr" in gtf file but it's not clear how and what to do exactly. I would really appreciated if someone could explain how to fix this problem.
I have ran this fastq file on other RNA aligners so it must something to do with GTF file.
Thank you for your help.
