Dear Michael, We're interested in identifying CNVs from a single exome dataset (data is Illumina paired-end, and there are no controls). Reading through the document of your tool exomeCopy, it seemed to me that exomeCopy can theoretically work on a single sample, but I'm still a little unsure about how the background read-depth would be estimated in that case, and whether or not it'd be meaningful. Can you please help clarify this? Thanks, Guru. -- Guru Ananda Computational Sciences Group The Jackson Laboratory 600 Main St, Bar Harbor ME 04609, USA Ph: 207-288-6290 Science is a way of thinking much more than it is a body of knowledge.

Hi Guru, It is possible to run exomeCopy without any calculated background read depth, using the GC content variables and the 'width' variable supplied to the X.names argument of exomeCopy(). Even better would be if you could find a few samples of "healthy" exomes which used the same enrichment kit as your dataset. By generating background from publicly downloaded exomes (we used ~10 from this dataset http://www.nature.com/ng/journal/v42/n11/full/ng.680.html ), we were more sensitive to detect duplications and deletions.
