I got this email from a user today:

"""
I saw you project DASCore and was interested to use it in a project where we measure with a Silixa iDAS. However, when I load tdms files, the distance coordinates appear to be shifted. I saw in the code that the starting point is "the starting point read from the file" + "total measured length" (dascore/io/tdms/utils.py, line 165: start = attr["StartPosition[m]"] + total_length). I would have removed the addition of the total length.

Is this a feature or a bug? I thought I could notify you about it!
"""

We need to look into this. @aissah, you wrote the TDMS parser, can you take a look in the next couple days?

Versions
