<p>I'm analyzing a tumor sample and a healthy sample from the same patient. I want to use sciClone to look at tumor clonality. One input is the genomic regions that need to be excluded due to LOH. I have both WES and WGS.</p>

<p>Is there currently a "gold standard" for which tool will return the most robust regions?</p>

<p>The sciClone paper mentions VarScan2, APOLLOH, HMMScan? Are these still state of the art?</p>

<p>Is it feasible to calculate LOH programmatically without the need of external software?</p>

I think you will need external software. What you have ended up with?
