ValueError during post process after manually editing port coordinates

[marcelgln]

First thanks for creating this. It is really helpful. I am new to EM simulation, so probably I miss some points.
I executed one of the examples, which produced sensible results.
Next, tried to simulate a GCPW from KiCad, the results where completely wrong.

Opened the geometry.xml in appCSXcad and noticed the ports where not at the expected position. In the pos.csv file I used the coordinates from KiCad (both drill and grid origin were at the same position) . I expect I have to do some calculations related to the size of the port, but didn't check that yet.
For a quick test I tweaked the csv file a bit until the ports were shown at a more sensible position.

However after running the simulation, the post processing resulted in the following error:

[11:32:00][INFO] Adding virtual ports
Traceback (most recent call last):

ValueError: the number of columns changed from 2 to 72 at row 24; use usecols to select a subset and avoid this error
