Thank you for your wonderful tool jconto! After adding the necessary libraries, all of the example functions in "testall.bat" were able to run except the damping ratio example "chanPe_dmp.ini". I found that the reason for this was the version of the Pandas library. I had installed Pandas using "pip install pandas", which installed the most recent version (v2.1.4). However, the Channels tool relies on the pandas "append" attribute which is depreciated in Pandas 2.x, which uses the attribute "concat" instead of "append" (https://stackoverflow.com/questions/7...). I uninstalled Pandas, then reinstalled using "pip install pandas==1.5.3" and then the damping ratio example worked. Posting here so that others can resolve the issue more quickly than I did.

Thanks again for sharing your hard work!

In addition to what Berwin said, you can use the fact that v34 will still read a v33 idv to convert from v33 to v34 of the idv if that's what you want to do. To demonstrate this, I used v33 to record in an IDV a change to a bus voltage monitored limit. PSSE v33 recorded the change using "BATBUSCHNG3". I then opened v34, opened the same case, then started an IDV recording. I then ran the v33 IDV and stopped the IDV recording. The resulting IDV is the bus change command in v34, "BATBUSCHNG4".

Hope this helps,
