Creating Circos cytogenic band data

I’m using circos to create a visual representation of genomic data, but I’m unable to create cytogenic bands that show up on the image. I’ve managed to create the basic ideogram used by: to depict a cancer genome but I can’t seem to decipher how the band data is stored in ‘hg18_karyotype_bands.tsv’, more specifically how the seventh column is used to generate bands. I’d appreciate any help. Thank you.

Hi @Vignesh_P, I think I can provide some help here. The 7th column is just a named color that you want to use for that band. There are a number of colors built in, here the staining colours are used.

band	chr1	p36.33	p36.33	0	2300000	gneg
band	chr1	p36.32	p36.32	2300000	5300000	gpos25
band	chr1	p36.31	p36.31	5300000	7100000	gneg
band	chr1	p36.23	p36.23	7100000	9200000	gpos25
band	chr1	p36.22	p36.22	9200000	12600000	gneg
