HVG and variation coefficient I'm looking for highly variable genes from a data set. I have calculated the coefficient of variation of the expressed genes of my dataset and inserted them in a histogram graph. Now I should select only the highly variable genes. Should I select genes with a coefficient of variation >1, or how?
thank you for your help,

regards
There seems to be a dividing line around CoV=0.9.  Perhaps this is a good place to start for a cutoff.
