Error when using sim.tags/sim.categories

[kaceyaurum]

I have this sim.

 1LQK/
 +-- nearest_neighbors/
 |   +-- K/
 |       +-- 2174.csv
 |       +-- 2186.csv
 +-- Sim.4b99d4bc-543a-4df5-bd5b-acf227d1c123.json
 +-- ligands/

 |   +-- PO4.mol2
 |   +-- all_ligands.mol2
 |   +-- all_ligands.pdb
 |   +-- PO4.pdb
 |   +-- MN.pdb
 +-- 1LQK.pdb
 +-- coordination/
 |   +-- K/

 |       +-- 2174/
 |           +-- pdData.h5
 +-- 1LQK.pqr
 +-- 1LQK-complete.pdb

When I try to use sim.tags on specifically this sim, I get the following error:

sim.categories returns the same error as well.

Has anyone had any similar issues?

what version of datreant are you using? This looks strange

[kaceyaurum]

0.6.1

You can try to update to the current version 0.7.1. But I don’t know where the error could come from maybe @dotsdl can help
