ValueError: Found b'\x82\xe0zOVP', expecting start of new VMP MODULE about galvani

I'm not sure what would cause that error but if you're reading the file live it might change the file while you are reading it.

If it works again after restarting it's probably ok to catch the error with a try: statement in the program and just reread the file again.

Yeah, I did consider that, but I'd prefer fixing the issue if I could :b

I'll just try to catch the error. Thank you.

Maybe the following is happening:

1. galvani reads the length of the data section
2. EC-Lab writes extra data to the file
3. galvani reads from the point where it expects the next section to be, using the outdated length information

In the case where the length of the current section is changed, the code could go back to the start of the section and reread the length. However, if change was to an earlier section then the header with the length information will also have moved. In that case I don't think there is any better solution than to go back to the start of the file and start reading again.
