ChIP-Seq Top2 in Yeast
Contents
Introduction
This wiki page combines the two sequencing experiments of ChIP-Seq on yeast samples udring June / July 2017.
Sample quality
In the above previous analyses, we undertook some Duplicate removel as this showed up to be an issue in the FastQC quality files.
However, the effect of this removal was very low. In any case, the MACS2 program takes care of duplicates so samples were only trimmed for adapters and quality.

Bam quality, filtering applied
The bam files were filtered both for mapping quality and low integrity reads in the following manner:
samtools view -b -F 1820 -q 48 <INBAMFILE> -o ${OUTBAMFILE> -@ <NUMTHREADS>
