Read mapping and variant calling
WebThere are several approaches to call variants. The simplest approach is to look for positions where the mapped reads consistently have a different base than the reference assembly … WebJan 15, 2014 · This customizable and modular system performs read mapping, read cleaning, and variant calling and annotation. At present, STORMSeq costs approximately $2 and 5–10 hours to process a full exome sequence and $30 and 3–8 days to process a whole genome sequence.
