Hi Chris,

I’m using the function ‘getEvents.m’ on a machine that has an earlier version of MWorks and the data comes from version 9. My code is crashing. Do the versions of MWorks in the data acquisition machine and processing machine have to match?

Thanks!

Hi Mariana,

> Do the versions of MWorks in the data acquisition machine and processing machine have to match?

Normally, no. However, MWorks 0.9 introduced a [new data file format](https://mworks.github.io/documentation/latest/reference/event_file_format/current.html), which the Python and MATLAB tools from earlier MWorks versions can’t read. So in this case, yes, you need MWorks 0.9 to read data files created by MWorks 0.9.

Cheers,  
Chris

Hi Chris,

Thank you for the answer. And will the new installation be backwards  
compatible? Meaning can I use the new version to process data from the  
older data format?

Thank you,

Yes, absolutely. The MWorks 0.9 data tools read both the old (.mwk) and new (.mwk2) file formats.
