102 **What it does**
|
|
|
103
|
|
|
104 This tool calculates the genome-wide coverage of intervals defined in a BAM or BED file and reports them in BedGraph format.
|
|
|
105
|
|
|
106 .. image:: $PATH_TO_IMAGES/genomecov-glyph.png
|
|
|
107
|
|
|
108 .. class:: warningmark
|
|
|
109
|
|
|
110 The input BED or BAM file must be sorted by chromosome name (but doesn't necessarily have to be sorted by start position).

|

|
114 **Example 1**
|
|
|
115
|
|
|
116 Input (BED format)-
|
|
|
117 Overlapping, un-sorted intervals::

|
|
|
122
|
|
|
123
|
|
|
124 Output (BedGraph format)-
|
|
|
125 Sorted, non-overlapping intervals, with coverage value on the 4th column::
|
|
|
126
|
|

127 chr1 100 120 1

|
135 **Example 2 - with ZERO-Regions selected (assuming hg19)**
|
|
|
136
|
|
|
137 Input (BED format)-
|
|
|
138 Overlapping, un-sorted intervals::
|
|
|
139
|
|
|
140 chr1 140 176

142 chr1 120 147
|
|
|
143
|
|
|
144
|
|
|
145 BedGraph output will contain five columns:
|
|
|
146
|
|
|
147 * 1. Chromosome name (or 'genome' for whole-genome coverage)
|
|
|
148 * 2. Coverage depth
|
|
|
149 * 3. The number of bases on chromosome (or genome) with depth equal to column 2.
|
|
|
150 * 4. The size of chromosome (or entire genome) in base pairs
|
|
|
151 * 5. The fraction of bases on chromosome (or entire genome) with depth equal to column 2.
|
