Tests This workflow takes as input SR BAM from ChIP-seq. It calls peaks on each replicate and intersect them. In parallel, each BAM is subsetted to smallest number of reads. Peaks are called using both subsets combined. Only peaks called using a combination of both subsets which have summits intersecting the intersection of both replicates will be kept.
Inputs
| ID | Name | Description | Type |
|---|---|---|---|
| 2 rmDup SR | #main/2 rmDup SR | A collection with 2 replicates. BAM should not have duplicates |
|
| bin_size | #main/bin_size | Bin size for average of normalized coverage |
|
| effective_genome_size | #main/effective_genome_size | Used by MACS2: H. sapiens: 2700000000, M. musculus: 1870000000, D. melanogaster: 120000000, C. elegans: 90000000 |
