I am about to commit some serious time to analyzing data produced on a SOLiD 5500 and I had a few questions about sequence quality. First off, does quality matter that much if I have >10 million reads per sample? Second, does quality seriously alter mapping with TOPHAT (RNAseq analysis)? I would think this is less of a problem then if I was doing SNP detection or something. Finally, I can filter the reads with quality scores below 10 easily in GALAXY, but then I lose ~55% of the reads! Seems like a lot. Here are some images pre and post filtering. Am I just trying too hard to clean up the data or should I filter? Thanks in advance.

The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...-

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-
