Aug 18, 2014   RSEM v1.2.16 is online now. Corrected a typo in 'rsem-generate-data-matrix', this script extracts 'expected_count' column instead of 'TPM' column.
Jun 16, 2014   RSEM v1.2.15 is online now. Allowed for a subset of reference sequences to be declared in an input SAM/BAM file. For any transcript not declared in the SAM/BAM file, its PME estimates and credibility intervals are set to zero. Added advanced options for customizing Gibbs sampler and credibility interval calculation behaviors. Splitted options in 'rsem-calculate-expression' into basic and advanced options.
Jun 8, 2014   RSEM v1.2.14 is online now. Changed RSEM's behaviors for building Bowtie/Bowtie 2 indices. In 'rsem-prepare-reference', '--no-bowtie' and '--no-ntog' options are removed. By default, RSEM does not build either Bowtie or Bowtie 2 indices. Instead, it generates two index Multi-FASTA files, 'reference_name.idx.fa' and 'reference_name.n2g.idx.fa'. Compared to the former file, the latter one in addition converts all 'N's into 'G's. These two files can be used to build aligner indices for customized aligners. In addition, 'reference_name.transcripts.fa' does not have poly(A) tails added. To enable RSEM build Bowtie/Bowtie 2 indices, '--bowtie' or '--bowtie2' must be set explicitly. The most significant benefit of this change is that now we can build Bowtie and Bowtie 2 indices simultaneously by turning both '--bowtie' and '--bowtie2' on. Type 'rsem-prepare-reference --help' for more information. If transcript coordinate files are visualized using IGV, 'reference_name.idx.fa' should be imported as a genome (instead of 'reference_name.transcripts.fa'). For more information, see the third subsection of Visualization in 'README.md'. Modified RSEM perl scripts so that RSEM directory will be added in the beginning of the PATH variable. This also means RSEM will try to use its own samtools first. Added --seed option to set random number generator seeds in 'rsem-calculate-expression'. Added posterior standard deviation of counts as output if either '--calc-pme' or '--calc-ci' is set. Updated boost to v1.55.0. Renamed makefile as Makefile. If '--output-genome-bam' is set, in the genome BAM file, each alignment's 'MD' field will be adjusted to match the CIGAR string. 'XS:A:value' field is required by Cufflinks for spliced alignments. If '--output-genome-bam' is set, in the genome BAM file, first each alignment's 'XS' filed will be deleted. Then if the alignment is an spliced alignment, a 'XS:A:value' field will be added accordingly. Added instructions for users who want to put all RSEM executables into a bin directory (see Compilation & Installation section of 'README.md').

Prebuilt RSEM Indices (RSEM v1.1.17) for Galaxy Wrapper
These indices are based on RefSeq containing NM accession numbers only. That means only curated genes (no experimental, no miRNA, no noncoding). Only mature RNAs. In addition, 125bp Poly(A) tails are added at the end of each transcript.
