I am doing RNA-seq analysis, I am trying to run cuffmerge for assembled transcripts files that have been generated by cufflinks but I have got the following error:
Fatal error: Error running cuffmerge:
[Fri Jul 13 04:32:00 2018] Beginning transcriptome assembly merge
[Fri Jul 13 04:32:00 2018] Preparing output location cm_output/ [Fri Jul 13 04:32:00 2018] Converting GTF files to SAM [04:32:00] Loading reference annotation. GFF Error: duplicate/invalid 'transcript' feature ID=gene104 [FAILED] Error: could not execute gtf_to_sam
Could you please help me to solve this problem, What should I do?
