 First, we determined what this histogram really shows in the distribution of template lengths, the length from the leftmost base mapped to the rightmost. This size includes the length of each read in the pair and the insert region between them.  First, we determined what this histogram really shows in the distribution of template lengths, the length from the leftmost base mapped to the rightmost.

-Both these distributions show smaller template lengths than the previous estimates (see [[computer_resources:​data|computer_resources:​data]]). The distribution for barcode 8 is especially odd because it appears to be cut off at 100. The read lengths for both barcodes were around 100 bps so any template length less than 200 represents a pair that can be joined. It was decided that SeqPrep should be run prior to mapping the reads to avoid these pairs that overlap.+Both these distributions show smaller template lengths than the previous estimates (see [[archive:computer_resources:​data|computer_resources:​data]]).
