WebOct 18, 2013 · Here we present PEAR, a fast and accurate paired-end read merger. PEAR merges reads by maximizing the assembly score (AS) of the read overlap via a scoring matrix that penalizes mismatches with a negative value β and rewards matches with a positive value α. Our approach takes quality scores and sequence matches into account. … WebUnlike paired end sequencing for other techniques like genomic resequencing or RNA-Seq, where you might expect the 2nd read to be located within the general vicinity of the first read, read-pairs from Hi-C should be processed independently (e.g. do not use Tophat, bowtie, bwa or any short read alignment software in "paired-end" mode - each read should … showing hidden files in macbook
