_pickle.UnpicklingError: invalid load key, '['

[amir-tagh]

Hello,

I am trying to move step by step with this analysis using the currently downloaded Zinc data base (6_p0.smi.gz) (/http://zinc12.docking.org/subsets/all-purchasable) but I am stuck in the beginning with the following error:

Traceback (most recent call last):
File "./different_fingerprint_analysis.py", line 47, in
m,nm = pickle.load(inf)
_pickle.UnpicklingError: invalid load key, '['.

I can not figure out the problem, I was wondering if someone can help.

Thanks,
Best,
Amir
