Unpacking mwk files with Windows

Support

Hi Chris,

Hope you had a good holiday season! Elia in our lab is wanting to look at some .mwk files, but he is a member of the Church of Windows And Linux, and does not wish to lay his hands upon a filthy Mac (his words, not mine…but I understand the sentiment). I sent him the matlab script from /Application Support/Mworks/Scripting/Matlab, but he says it relies on a compiled mex file in the mac format and cannot run on his computer. Would it be possible to compile that file in a windows mex format so he can unpack the data files? If not, is there a good way to save an unpacked database so I can unpack it and send it to him?

Thanks,

Simon

Hi Simon,

No. See this discussion for more info.

Other folks have developed tools for reading MWorks data files on non-Mac systems, but I can’t provide any support for this. See this comment for details.

If not, is there a good way to save an unpacked database so I can unpack it and send it to him?

If you’re using MATLAB, you could read out all the events with getEvents, then write the resulting array to a .mat file. If you’re using Python, maybe try pickle?

Cheers,
Chris

Ah, too bad but makes sense. Pickling it could work but won’t the pickles
be really huge? I really only want to send him the eye movements – would
there be a simple way to unpack just those and save them to a csv?

Well, you could extract the events you want, then write out their values using csv.writer. That seems pretty simple.
