 If you are using a GTF file for the "UCSC Genes" gene set from the UCSC Genome Browser, then the "knownIsoforms.txt" file (obtained from the "Downloads" section of the UCSC Genome Browser site) is of this format.
 
 If this option is off, then the mapping of isoforms to genes depends on whether the --gtf option is specified.  If --gtf is specified, then RSEM uses the "gene_id" and "transcript_id" attributes in the GTF file.  Otherwise, RSEM assumes that each sequence in the reference sequence files is a separate gene.
