What's the format of the bed file for plotting?

[mocksu]

The manual has the following command to plot

IND='HG02481'; python plot_karyogram.py
--bed_a ${IND}_A.bed
--bed_b ${IND}_B.bed
--ind ${IND}
--out ${IND}.png

What's the format of the .bed file? Can you give an example? Does it look like the following?

21 100 200 EUR 21 200 800 AFR ...

One .bed file for hap1, and the other for hap2?

Thanks so much!

I think this is what you are looking for: https://github.com/slowkoni/rfmix/issues/15#issuecomment-490323478

Yes, the input is two .bed files, but it looks different than you provided (and it doesn't strictly confirm to the .bed file format). I've copied over the relevant part of that issue thread here:

I figured out the "TRACTS-compatible" .bed format here:

Also, I had to set "X" to "23" in the centromeres_hg19.bed file, in order to get a .bed file in the following format to work:

23	1	155270560	ACB	0	202.1689

In other words, as described in the tracts documentation, the file format should be as follows:

chrom	begin	end	assignment	cmBegin      cmEnd

I hope this helps!

P.S. Either you or Alicia has to close the issue :)
