WebSep 9, 2024 · Step 1: input paired-end raw reads are aligned to the reference genome with special care for short-read trimming and alignment. Step 2: peaks are called based on fragment pileup. A fixed window around the summit of each peak is … WebEven so, longer reads are more likely to contain sequencing errors which will artificially increase the observed diversity and will tend to underrepresent highly duplicated sequences. The plot shows the proportion of the library which is made up of sequences in each of the different duplication level bins. There are two lines on the plot.

WebMar 20, 2024 · The duplication rate is the fraction of mapped reads where any 2 reads share the same 5′ and 3′ coordinates. Duplicates mostly arise from the PCR step during library … WebOur Ribo-seq libraries involved a PCR step (9 cycles of amplification) in order to get enough material to put on the sequencer. Because of this, we expect that many of the reads are actually exact duplicates of clones which are not real duplicates but arise as an artifact of PCR.
