genomic coordinates. Alignments of reads that have identical genomic
coordinates (i.e., alignments to different isoforms that share the
same genomic region) are collapsed into one alignment. The MAPQ field
-of each alignment is set to max(100, floor(-10 * log10(1.0 - w) +
+of each alignment is set to min(100, floor(-10 * log10(1.0 - w) +
0.5)), where w is the posterior probability of that alignment being
the true mapping of a read. In addition, RSEM pads a new tag
ZW:f:value, where value is a single precision floating number
