end of chromosome in .bed format

Question

[carlin.daniel]

Is there a way to specify the end of a chromosome in a .bed file without knowing how long each one is?

[Devon Ryan]

No, there's not, at least in general.

.... but you can get the length from fetchChromSizes <genome>, e.g.:

fetchChromSizes hg19 > output_file
