74 **What it does**
|
|
|
75
|
|
|
76 This tool creates a new BAM alignment file based on alignments that overlap (or optionally, those that do not overlap) intervals in another BED file. Example usage would be to cull a BAM file from an exome capture experiment to include on the "on-target" alignments.
|
|
|

|
|
|
78 .. class:: infomark
|
|
|
79
|
|
|
80 Note that each BAM alignment is treated individually. Therefore, if one end of a paired-end alignment overlaps an interval in the BED file, yet the other end does not, the output file will only include the overlapping end.
|
|
|
81
|
|
|
82 .. class:: infomark
|
|
|
83
|
|
|
84 Note that a BAM alignment will be sent to the output file **once** even if it overlaps more than one interval in the BED file.
