This update addresses the cases skewed marker gene ranking of:

  • Some cell types are much more abundant than others.
  • Some patients have many more cells than others.

It also switches from a moderated t-test to the similar Cohen's d implemented in C++ for speed in scran_markers. This also avoids QR matrix decomposition and matrix inversion, which linear modelling does.


Dependency

scrapper package is not yet in Bioconductor. So, this change should not be merged before then.
