WebThe RSEM expected counts from the TCGA project will work fine with either limma-voom or edgeR. However, with such a large number of samples, limma-voom is easily the best choice from a computational point of view. (Note I mean voom, not vooma.) None of the other data columns are usable and you must not do any data transformation.

WebProviding the correct value is important for RSEM. If RSEM runs Bowtie, it uses this value for Bowtie's seed length parameter.
