This is probably an issue with giving input files as relative paths. Could you please have another look at our published data folder structure? The script and the GUI are really built with this folder structure in mind, and the script is only guaranteed to work well with this structure.

https://www.repository.cam.ac.uk/handle/1810/303161

So, when starting a new calculation, please make a new directory, copy your 3D sdf structures in there. The process generally expects to have either 1 structure with possible diastereomers, which are then generated automatically, or several explicit structures without diastereomer generation. The folder also should contain the NMR data - either description, or raw Bruker NMR data folder. So you should have a folder with just 1 or more sdf files and either and NMR text file or raw NMR data. Then the standard way of launching the command line DP4-AI, as explained in the included README file, is to cd into that folder and then launch the script as

PyDP4.py -w gmns -s chloroform Candidate CandidateNMR
for structure with 2 or more chiral centres or
PyDP4.py -w gmns -s chloroform Candidate1 Candidate2 CandidateNMR
for other types of isomers, where Candidate corresponds to Candidate.sdf file in the same folder. No paths are then needed or expected anywhere, just file names for structures and a file name or subfolder name for NMR data.

I suspect the other issues that you have reported ultimately come from not following this convention as well.
