Yes. Save and reuse Hessian matrix for two-component deconvolution is the default option. The ESTIMATE score cutoffs in the pipeline were chosen based on our observations of overall distribution of ESTIMATE score in TCGA HNSC samples. It is cancer-specific cutoff. I suggest you need to look at your data and determine your own cutoffs. The goal of this step is to find samples with relative high tumor proportions.
Thank you for the clarification!
Hi,
I am trying to run DeMixT multiple times from the same notebook, following a workflow very similar to that of Fig. S11.
I noticed that a Hessian is calculated and saved from my first call to DeMixT and then reused for my second call. I just wanted to be sure that the Hessian doesn't need to be recalculated and this is the intended behavior for my use case.
Lastly, I think I grasp the motivations behind partitioning the tumor samples into stromal and immune-like groups. However, it was unclear to me how the ESTIMATE score cutoffs were chosen.
Thank you!
David
