3.2.1 Read mapping consideration
Reads mapping consideration
In the context of Hi-C methods which are not based on restriction enzyme digestion, no filtering of restriction fragments is applied. The uniquely mapped read pairs are directly used to build the contact maps. However, during the process of ligation (with blunt ends) and sonication one may get many kinds of artifacts can be uniquely mapped to the genome, but doesn't make any sense. So we would like to dive deep into how these unwanted fragments come from.
Actually, we are more interested in intra-chromosomal interaction at 0:39.
