@CedricPatzer Could you provide an example of the header where it fails?
Also, are you using MTData.from_modem()? If not try that.
from mtpy import MTData
md = MTData()
md.from_modem(modem_data_filename)from mtpy-v2.

Hello
I am having a similar issue as @CedricPatzer. I have tested with two ModEM files, one file of my own and one that I downloaded from the old repo of mtpy (https://github.com/MTgeophysics/mtpy/blob/develop/examples/data/ModEM_files/ModEM_Data.dat).
My version of MTpy is 2.0.6
import mtpy
from mtpy import MTData
datafile = 'datos3.dat'
#datafile = 'ModEM_Data.dat'
md = MTData()
md.from_modem(datafile)With my modem file (datos3.dat) I get the following error
---------------------------------------------------------------------------
IndexError Traceback (most recent call last)
Cell In[9], line 8
5 datafile = 'datos3.dat'
