 ## <a name="introduction"></a> Introduction
 
 RSEM is a software package for estimating gene and isoform expression
-levels from RNA-Seq data.  The new RSEM package (rsem-1.x) provides an
-user-friendly interface, supports threads for parallel computation of
-the EM algorithm, single-end and paired-end read data, quality scores,
-variable-length reads and RSPD estimation. It can also generate
-genomic-coordinate BAM files and UCSC wiggle files for
-visualization. In addition, it provides posterior mean and 95%
-credibility interval estimates for expression levels. For
-visualization, it can also generate transcript-coordinate BAM files
-and visualize them and also models learned.

+both transcript-coordinate and genomic-coordinate. Genomic-coordinate
+files can be visualized by both UCSC Genome browser and Broad
+Institute's Integrative Genomics Viewer (IGV). Transcript-coordinate
+files can be visualized by IGV. RSEM also has its own scripts to
+generate transcript read depth plots in pdf format. The unique feature
+of RSEM is, the read depth plots can be stacked, with read depth
+contributed to unique reads shown in black and contributed to
+multi-reads shown in red. In addition, models learned from data can
+also be visualized. Last but not least, RSEM contains a simulator.

Note: Although IGV can generate read depth plot from the BAM file given, it cannot recognize "ZW" tag RSEM puts. Therefore IGV counts each alignment as weight 1 instead of the expected weight for the plot it generates. So we recommend to use the wiggle file generated by RSEM for read depth visualization.
