I am getting the following error and wondering what it is, what can cause it and if it is possible to bypass it.

--- frame 1 score inf

--- writing coordinates

Traceback (most recent call last):

NameError: name 'inf' is not defined

It is for modeling of a protein system that was working well when using only crosslinking data, but giving me this error when trying to use either EM or EM + XL as scoring functions. The same EM map and configuration is working fine for a very similar domain (same fold, very similar size). So not sure why it wouldn't work in this case.
