I am using cuffmerge to merge 6 different transcripts.gtf generated by cufflinks. When I execute with 'Use Sequence Data' option set to YES and choose genome.fa from history, I get "The selected case is unavailable/invalid." for the Use Sequence Data field.
My genome.fa file is fine and was used for Index/alignments with the STAR aligner.
Could someone please help?
thanks in advance,
