In some cases ASCAT fails to create a model for tumor purity and average ploidy. I have seen this in one case so far, but it is known that it happens for a certain fraction of tumors that are particularly complicated to assess.
In such cases it would be good if part of the output from "runAscat" is still copied to the VariantCalling/Ascat folder. For example, the plots of raw data (xxx.tumor.png) and segmented data (xxx.ASPCF.png). This is useful information, especially together with a note that "ascat failed to find an estimation of average ploidy and purity").
