**What it does**

This tool identifies common intervals among multiple, sorted BED files. Intervals can be common among 0 to N of the N input BED files.


.. class:: warningmark

This tool requires that each BED file is reference-sorted (chrom, then start).


.. class:: infomark

The output file will contain five fixed columns, plus additional columns for each BED file:

    * 1. Chromosome name (or 'genome' for whole-genome coverage).
    * 2. The zero-based start position of the interval.
    * 3. The one-based end position of the interval.
    * 4. The number of input files that had at least one feature overlapping this interval.
    * 5. A list of input files or labels that had at least one feature overlapping this interval.
    * 6. For each input file, an indication (1 = Yes, 0 = No) of whether or not the file had at least one feature overlapping this interval.

------

**Example input**::

    # a.bed
    chr1  6   12bed
    chr1  10  20
    chr1  22  27
    chr1  24  30

    # b.bed
    chr1  12  32
    chr1  14  30

    # c.bed
    chr1  8   15
    chr1  10  14
    chr1  32  34


------

**Example without a header and without reporting intervals with zero coverage**::


    chr1	6	8	1	1	1	0	0
    chr1	8	12	2	1,3	1	0	1
    chr1	12	15	3	1,2,3	1	1	1
    chr1	15	20	2	1,2	1	1	0
    chr1	20	22	1	2	0	1	0
    chr1	22	30	2	1,2	1	1	0
    chr1	30	32	1	2	0	1	0
    chr1	32	34	1	3	0	0	1


**Example adding a header line**::


    chrom	start	end	num	list	a.bed	b.bed	c.bed
    chr1	6	8	1	1	1	0	0
    chr1	8	12	2	1,3	1	0	1
    chr1	12	15	3	1,2,3	1	1	1
    chr1	15	20	2	1,2	1	1	0
    chr1	20	22	1	2	0	1	0
    chr1	22	30	2	1,2	1	1	0
    chr1	30	32	1	2	0	1	0
    chr1	32	34	1	3	0	0	1


**Example adding a header line and custom file labels**::


    chrom	start	end	num	list	    joe	bob	sue
    chr1	6	8	1	joe	    1	0	0
    chr1	8	12	2	joe,sue	    1	0	1
    chr1	12	15	3	joe,bob,sue 1	1	1
    chr1	15	20	2	joe,bob	    1	1	0
    chr1	20	22	1	bob	    0	1	0
    chr1	22	30	2	joe,bob	    1	1	0
    chr1	30	32	1	bob	    0	1	0
    chr1	32	34	1	sue	    0	0	1
