Hey Chris, I was wondering whether converting legacy .mwk files to .mwk2 files is possible. I saw a mwk2writer added to the nightly build but I do not see much documentation. RT Raghavan Movshon Lab ---

Hi RT, The Python `mworks.data` module does include an undocumented `_MWK2Writer` class. It’s there to help with automated testing of the module, but you could also use it to convert an MWK file to MWK2 format. The attached script implements such a converter. To use it: ``` python3 convert_to_mwk2.py data.mwk data.mwk2 ``` Cheers, Chris [convert\_to\_mwk2.py.zip](https://mworks.discourse.group/uploads/short-url/6BeY3dJeVLpaerYfjwSS5nl0fTv.zip) (511 Bytes) ---
