-Generate a BAM file, 'sample_name.bam', with alignments mapped to genomic coordinates and annotated with their posterior probabilities. In addition, RSEM will call samtools (included in RSEM package) to sort and index the bam file. 'sample_name.sorted.bam' and 'sample_name.sorted.bam.bai' will be generated. (Default: off)
+Do not output any BAM file. (Default: off)

+When RSEM generates a BAM file, instead of outputing all alignments a read has with their posterior probabilities, one alignment is sampled and outputed according to the posterior probabilities. If the sampling result is that the read comes from the "noise" transcript, nothing is outputed. (Default: off)
