Read before use
1, check data with precheck (windows version) tools
2, data from excel, copy and paste data into the input frame
3, data from txt, must tab-seperated, copy and paste data into the input frame
4, specieal and non-English characters such as #, <, >, %, (, ), α are not friendly
5, use point as decimal separator, not comma. e.g. 3.14, not 3,14 as pi
Note: only for chromosome region (peaks) overlap, i.e. chr start end

Genomic regions (peaks) overlap venn diagram

Introduction
Using venn diagram to show the overlapped genomic numbers. Please contact us for more than 6 datasets.
Input data instructions
If ignore strand, input data must contain 3 columns (bed3 format): chromsome, start, end
If consider strand, input data must contain 6 columns (bed6 format): chromosome, start, end, name, value, strand
Output contains sets results. For example, if a.bed and b.bed to overlap, then a.bed specific is 10_a.bed. b.bed specific is 01_b.bed. Overlap is 11_a_b.bed. Since it exists many-to-many results, the number in venn often not the same to the original bed lines. Paper example
Intervene: a tool for intersection and visualization of multiple gene or genomic region sets Fig 2A.
Input
