Usage sum of each cell is over 1

[juneE-cloud]

Thank you for creating this excellent package!

Following the provided tutorial (analyze_pbmc_example_data.ipynb), I successfully reproduced nearly all the results in my jupyter notebook, however, surprisingly, I found that the file "pbmc_cNMF.usages.k_7.dt_0_1.consensus.txt" showed extremely low usage (see below).

According to the tutorial, this matrix should be normalized to sum to 1, but I observed some values are over 1.

Is it correct?

Looking for your kind reply.

Happy Christmas Eve, btw :)
