RSEM (RNA-Seq by Expectation-Maximization)


Jun 27, 2018   RSEM v1.3.1 is online now. Added `--gff3-genes-as-transcripts` option for `rsem-prepare-reference`. This option will allow RSEM to treat genes as transcripts.

Oct 3, 2016   RSEM v1.3.0 is online now. Added Prior-Enhanced RSEM (pRSEM) as a submodule. Introduced `--strandedness <none|forward|reverse>` option, `--strand-specific` and `--forward-prob` are deprecated (but still supported). Revised documentation for `rsem-plot-model`, maked it clear that in alignment statistics, isoform-level (instead of genome-level) multi-mapping reads are shown. Significantly improved the output information of `rsem-sam-validator`: if indels/clippings/skips are detected in alignments or alignments exceed transcript boundaries, `rsem-sam-validator` will report them instead of telling you the input is valid. Updated the warning message to ask users to make sure that they align their reads agains a set of transcripts instead of genome when RSEM finds less sequences in the BAM file than RSEM's indices.

Jun 4, 2016   RSEM v1.2.31 is online now. Rewrote 'rsem-gff3-to-gtf' to handle a more general set of GFF3 files. Added safety checks to make sure poly(A) tails are not added to the reference when '--star' is set.

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.

Mouse Indices, extracted from mouse genome mm9

Human Indices, extracted from human genome hg18
