Hi,

I tried clustering your matrix (HeatMap.txt) using Clustergrammer-PY and it gave the same error about an empty matrix

raise ValueError("The number of observations cannot be determined on "
ValueError: The number of observations cannot be determined on an empty distance matrix.

This is happening because you only have a single column with non-zero values. If you try adding another non-zero number to another column your data will cluster. Let us know if that helps.

Best,
Nick
