-After removing adapters and PCR duplicates, we run FastQC in two of the libraries. In general, the quality of the reads decrease in the last base-positions. Also, read 2 of the SW019 library shows problems in the per tile sequence quality. Bellow are the pdf files with the fastqc for the PCR and adapter removed libraries. The protocol we used to run fastqc is uploaded in this link: [[fastqc:​fastqc]]. The path to the files is: campusdata/​gchaves/​fastqc_trimmed_PCR_duplicates.+After removing adapters and PCR duplicates, we run FastQC in two of the libraries.
