Matlab native for M1 apple beta and brainstorm -nogui

Discussions

Dear Brainstorm team,

Apple has released native beta
Exploring the MATLAB beta for Native Apple Silicon » The MATLAB Blog - MATLAB & Simulink (mathworks.com)
I am playing with it, and the brainstorm 'nogui' doesnt start, with the following error

Error using bst_get
Unsupported extension.

Error in bst_plugin>GetSupported (line 125)
    OsType = bst_get('OsType', 0);

Error in bst_plugin>MenuCreate (line 2193)
    PlugDesc = GetSupported();

Error in bst_plugin (line 110)
eval(macro_method);

Error in gui_brainstorm>CreateWindow (line 173)
        jMenusPlug = bst_plugin('MenuCreate', jMenuPlugins, fontSize);

Error in gui_brainstorm (line 33)
eval(macro_method);

Error in gui_initialize (line 30)
GlobalData.Program.GUI = gui_brainstorm('CreateWindow');

Error in bst_startup (line 359)
gui_initialize();

Error in brainstorm (line 103)
        bst_startup(BrainstormHomeDir, 1, BrainstormDbDir);

This is probably because this beta has problem with how native m1 release support graphics atm
I putting this here so you will have this under radar, the Matlab team asks for feedback and evaluation
https://nl.mathworks.com/support/apple-silicon-r2022a-beta.html
in case something is needed to support Brainstorm native under M1 users may push for it now

Also in my understanding, brainstorm -nogui shouldnt try to initialize gui, which is the problem here

EDIT: The real reason of error is that the mexext isn' supported yet for mexmaca64,

i dont expect that it will happen before official release of Matlab for apple architecture in Autumn, I am just discussing this on forum here :wink:

Wow !! That’s a great news if MATLAB is finally native for the M1 Mac ! Thanks for the info.

The real reason of error is that the mexext isn' supported yet for mexmaca64,

I added "maca64" in the list of supported mex extensions: (Added mex extension mexmaca64 for Mac ARM M1 systems · brainstorm-tools/brainstorm3@98927dd · GitHub)

Please update Brainstorm and try again.

brainstorm nogui starts the GUI internally but doesn't show it.
brainstorm server works without Java (and without any graphical elements).

Matlab2022b is officially out : Release Notes for MATLAB - MATLAB & Simulink

As soon as I get my hand on a license, I will do some tests. I guess we might need to recompile some mex for the M1 chip :slight_smile:

Edit: it seems matlab2022b is still using rosetta ... Mac System Requirements - MATLAB & Simulink

Matlab native for M1 was released as beta under R2022b, beta will be open until end of June
https://blogs.mathworks.com/matlab/2022/12/08/playing-with-the-r2022b-matlab-apple-silicon-beta-for-m1-m2-mac/

I suppose that the plan is to release officially M1 version under R2023b

I tried to run some brainstorm function with M1 native installation, and they are much more slower the running them in Matlab under Rosetta :frowning:
