[BUG] Hard-Coded Columns for readBioLogic about impedance.py HOT 1 CLOSED

👋 @nickbrady thanks for filing the issue and sharing your solution! In this case, I think parsing the columns is great. Would you be willing to submit a pull request (feel free to post here if you have any questions)?

One suggestion I might make is that I think this solution will throw an index error if a column doesn't exist (when it tries to get the [0] from an empty list), so it'd probably be good to add a step to check that it exists first and raise a more meaningful error, e.g.

headers = lines[number_header_lines-1].split('\t')
freq_cols = [o for o, h in enumerate(headers) if h == 'freq/Hz']
ReZ_cols = [o for o, h in enumerate(headers) if h == 'Re(Z)/Ohm']
ImZ_cols = [o for o, h in enumerate(headers) if h == '-Im(Z)/Ohm']

for cols in [freq_cols, ReZ_cols, ImZ_cols]:
    assert len(cols) > 0, f'{cols} not found in header ({headers})'

freq_col = freq_cols[0]
ReZ_col = ReZ_cols[0]
ImZ_cols = ImZ_cols[0]
