**What it does**

This tool allows ChIP-seq peak calling using SPP

This set of programs operate on mapped Illumina single-end read datasets in tagAlign or BAM format.

View the modified SPP documentation: http://code.google.com/p/phantompeakqualtools/

------

**Usage**

**Determine strand cross-correlation peak**: Compute the predominant insert-size (fragment length) based on strand cross-correlation peak.

**Peak calling**: Call Peaks and regions for punctate binding datasets.

**IDR analysis**: Compute Data quality measures based on relative phantom peak.

**Custom settings**: Enables all options available to SPP for custom analysis.
