BEDPE file for ENCODE 3D chromatin structure data

BEDPE file for ENCODE 3D chromatin structure data

0

Hi,

I am looking at 3D chromatin structure data on ENCODE. Regarding the BEDPE file, I can understand the first 10 columns that are based on the general BEDPE file format but I don’t know what additional fields after those 10 columns are representing.

For ‘TAD’ BEDPE file, the header is:

#chr1   x1  x2  chr2    y1  y2  name    score   strand1 strand2 color   f2  f3  f4  f5

What are the last four fields: f2, f3, f4, f5?

For ‘long range chromatin interaction’ BEDPE file, the header is:

#chr1   x1  x2  chr2    y1  y2  name    score   strand1 strand2 color   e_bl    e_donut e_h e_v fdr_bl  fdr_donut   fdr_h   fdr_v   num_collapsed   centroid1   centroid2   radius          

I want description of the fields. I couldn’t find it on ENCODE file format webpage and by looking ‘Juicer tool’ (used to generate these files as mentioned by ENCODE) paper.

Would be very thankful for any help.
