90 **What it does**
|
|
|
91
|
|
|
92 This tool requires the output from computeGCBias to correct the given BAM files according to the method proposed by Benjamini and Speed (2012). Nucleic Acids Res.
|
|
|
93 The resulting BAM files can be used in any downstream analyses, but be aware that you should not filter out duplicates from here on.
|
|
|
94
|
|
|
95 **Output files**:
|
|
|
96
|
|
|
97 - GC-normalized BAM file
