I'd like to perform some differential expression analysis on RNA-Seq and miRNA-Seq data from CGHub. I've noticed the "validation" strategy among library strategies at CGHub, that is defined by EBI as "CGHub special request. Independent experiment to re-evaluate putative variants. Micro RNA sequencing strategy designed to capture post-transcriptional RNA elements and include non-coding functional elements." I'd like to get more information about this kind of library. Should I prefer it over usual RNA-Seq strategy, and why ?
