Hey guys,
first, thank you that you are working on it... Biologics MPR files are really a bit crappy.
I could work with GCPL data smoothly, but have issues with PEIS measurements. (See error in Title).
MPR files are created by EC-Lab 11.62.9 and I am working with the newest version of galvani 0.5.0.
If you need any more information please let me know!
