step 11 with metadata: IndexError: list index out of range

[NA1919]

Hi,

I am running panX to calculate branch associations. I have a file to describe my metadata and another file of the numbers for the association. It works just fine until I get to step 11, then I get this Error:

Traceback (most recent call last):

IndexError: list index out of range

What does this mean? I would appreciate any help!
