Problem with phonopy, cp2k_input_tools and transitions

[luizfcpe]

I have found an error message when building supercells with atomic displacements using a combination of phonopy (2.23.1, 2.24.1, 2.24.2), cp2k_input_tools (0.9.1, 0.8.2, 0.7.2, 0.6.0, etc) and transitions (0.8.11, 0.7.2, 0.7.0, etc), also python versions 3.8 and 3.12. I do not understand the error message below, so I will appreciate any suggestions. Thanks.

For the record, I get the same error message on RedHat Enterprise Linux 7 and Mac OS Sonoma 14.3.1

Ok, so I can run the NaCl example that comes with phonopy. I should have checked that before. Nonetheless, my input file aGST_ENERGY_FORCE.inp runs fine in CP2K 2024.1. Perhaps there is something in that file that transitions or cp2k_input_tools do not like, although it is within the syntax rules of CP2K. Any advice is highly appreciated.

Found the problem. One of the comments contained quotation marks "". For some reason transition didn't like that, even though CP2K accepts this type of thing.
