Error when loading frequencies

[jalemkul]

I am having a problem loading frequencies from a calculation performed with G09. The first 15 frequencies load fine, but any attempt to load a higher frequency leads to an error, as shown below. I can send the output file privately but I do not wish to upload it here.

missing operator at @

I am using molUP 1.7.1 (directly cloned and installed from this repo) and VMD 1.9.3 on Ubuntu 18.04. Thanks for any help!

Hello, it might be too late but I had the same problem. By commenting the line 482 set molUP::nFreqToRead 5 in molUP/molUP/lib/readFreq.tcl, it seems to resolve the issue for the calculation of all frequencies and the corresponding vectors.
