Hi there,

What are peoples thoughts on using the ambiguous chromosomes in their reference assembly for mapping reads....
for example these....

No technical problem with using the ambiguous chromosomes; I have done so when required. If you will get any useful information from doing so is a different matter. It depends on your project.

Thanks for your response westerman,

I question whether we get useful information also. Currently we are doing some WGS. when have you been required to include the ambiguous chromosomes?

I'm interested in a gene that is on an ambiguous chromosome so I always include all of them when aligning my chip-seq data. I'm using mouse. I get good alignments to some regions on these ambiguous chromosomes.
