Hi,
I'd like to apply your method to my research problem (computational systems biology).
I'm trying to run fit method with my data (2d array, dim: 30 x 13800) and keep getting the following error:

Warning: Data matrix values should be consecutive integers starting with 0,1,...
Traceback (most recent call last):

I've tried to run it both with python 2.7 and 3.4 as a script.
I'd be grateful for any suggestions.
