When one tries to convert a csv file resulting from measurements without temperature control, the following error is output:
ValueError: could not convert string to float: '-'
The error occurs because the code assumes that the values in the 9th column (8th starting from the 0th column) are numbers. However, when no temperature control is used during measurements, there is only a dash instead of the temperature value.
The code should be able to distinguish between both file possibilities (with or without temperature control) and handle the file conversion accordingly.
The csv file that triggered this error is attached. The extension has been changed to .txt, but the file structure remains unaltered.
