[…] using a cut-off e-value of 10−5. to eliminate the influence of different gene lengths and sequence discrepancies on expression calculations, gene expression levels based on read counts obtained by rsem (version v1.2.15) were normalized using fpkm (fragments per kilo bases per million fragments) transformation (li and dewey 2011). the calculated gene expression levels were used for direct […]

[…] were performed by blastx with a cut-off e-value of 1e-5. unigenes having no homologs in the nr and swissprot databases were scanned using estscan [28]., gene expression levels were estimated by rsem [29]. for each sample, two biological replicates were sequenced and the correlation coefficients (r2) between replicates were calculated using pearson correlation. subsequently, the differential […]

[…] raw paired-end illumina reads (sra062458 and srp071466) were cleaned and trimmed using trimmomatic (bolger et al. 2014) and were used to estimate expression of αa and αd-globin in each species with rsem (li and dewey 2011). transcripts per million (tpm) was used as the expression metric., we integrated synteny, phylogenetic, and expression analyses to reconstruct the evolution of the α- […]

[…] pm and sequenced on a nextseq 500 (illumina)., rna-seq reads were aligned to the refseq hg38 transcriptome (grch38.2) using bowtie2 [49]. the resulting transcriptomic alignments were processed by rsem to estimate the abundance (expected counts and transcripts per million [tpm]) of refseq transcripts [50]., several genes were quantified multiple times due to alternative isoforms unrelated […]

Usefull if you want to estimate isoform expression in your RNA-seq. It uses Bowtie by default but you can map with another mapper and just use BAM/SAM file, so RSEM is quite flexible. Routinely used in TCGA workflow, but I would like to highlight that their RSEM UCSC isoforms IDs are sometimes different from Official UCSC isoforms IDs, no idea why...
