Description

This track shows the meta summits from Imbeault et al 2017. This study was a large scale ChIP-SEQ "screen" of ~200 KRAB Zinc Finger proteins HA tagged and expressed in 293 cells.

Meta summits are initially set to be read at a threshold score of 100 (macs2 summit score).

Use in combination with the corresponding coverage and instance mapping tracks.

Methods

Using the Repeat Browser bed files (see "instance mapping tracks") we used macs2 to call peaks with the following settings

macs2 callpeak -f BED -t --keep-dup all --outdir data/macs2/ --nomodel --call-summits --extsize 30 -n

macs2 summits and peaks can be found in data/macs2 if you would like to load custom tracks with less stringently filtered meta summits.
