33 **What it does**
34
35 This is a wrapper for intersecBed.
36
37 Program: intersectBed (v2.13.3)
38 Author: Aaron Quinlan (aaronquinlan@gmail.com)
39 Summary: Report overlaps between two feature files.
40
41 Usage::
42
43 intersectBed [OPTIONS] -a (bed/gff/vcf) -b (bed/gff/vcf)
44
45 Options::
46 -abam The A input file is in BAM format. Output will be BAM as well.
47
48 -ubam Write uncompressed BAM output. Default is to write compressed BAM.
49
50 -bed When using BAM input (-abam), write output as BED. The default
51 is to write output in BAM when using -abam.
52
53 -wa Write the original entry in A for each overlap.
54
55 -wb Write the original entry in B for each overlap.
56 - Useful for knowing _what_ A overlaps. Restricted by -f and -r.
57
58 -wo Write the original A and B entries plus the number of base
59 pairs of overlap between the two features.
60 - Overlaps restricted by -f and -r.
61 Only A features with overlap are reported.
62
63 -wao Write the original A and B entries plus the number of base
64 pairs of overlap between the two features.
65 - Overlapping features restricted by -f and -r.
66 However, A features w/o overlap are also reported
67 with a NULL B feature and overlap = 0.
68
69 -u Write the original A entry _once_ if _any_ overlaps found in B.
70 - In other words, just report the fact >=1 hit was found.
71 - Overlaps restricted by -f and -r.
72
73 -c For each entry in A, report the number of overlaps with B.
74 - Reports 0 for A entries that have no overlap with B.
75 - Overlaps restricted by -f and -r.
76
77 -v Only report those entries in A that have _no overlaps_ with B.
78 - Similar to "grep -v" (an homage).
79
80 -f Minimum overlap required as a fraction of A.
81 - Default is 1E-9 (i.e., 1bp).
82 - FLOAT (e.g. 0.50)
83
84 -r Require that the fraction overlap be reciprocal for A and B.
85 - In other words, if -f is 0.90 and -r is used, this requires
86 that B overlap 90% of A and A _also_ overlaps 90% of B.
87
88 -s Require same strandedness. That is, only report hits in B that
89 overlap A on the _same_ strand.
90 - By default, overlaps are reported without respect to strand.
91
92 -S Require different strandedness. That is, only report hits in B that
93 overlap A on the _opposite_ strand.
94 - By default, overlaps are reported without respect to strand.
95
96 -split Treat "split" BAM or BED12 entries as distinct BED intervals.
97
98 -sorted Use the "chromsweep" algorithm for sorted (-k1,1 -k2,2n) input
99 NOTE: this will trust, but not enforce that data is sorted. Caveat emptor.
