Music2 bug in "music2_prop_t_statistics" function

[ste-depo]

Error:

Error in (function (classes, fdef, mtable)  : 
  unable to find an inherited method for function ‘exprs’ for signature ‘"matrix"’

The actual code tries to extract expression from "bulk.case" pretending it is an object of ExpressionSet class, while it's already a matrix.

Removing exprs() fixes the bug

Yes. Reached the same conclusion, and lost a couple of hours. Too bad I didn't see your post first.

Thanks for documenting. I just ran into this issue using MuSiC installed from tutorial instructions, so it has not yet been resolved on that branch.

Has anyone found a solution for this issue yet?
