I tried deleting configuration files(.brainstorm) and re-downloading the folder ”brainstorm3” but it just doesn’t work. The same error occurs repeatedly.

I think this is an issue with shadowing the Matlab function strjoin.

  1. Restart Matlab, then before running Brainstorm, run in the Matlab Command Window the command:

which('strjoin', '-all')

it should give you the path of the Matlab built-in function strjoin:
C:\Program Files\MATLAB\R202Xx\toolbox\matlab\strfun\strjoin.m

If it does not point to that file, that's is the issue, remove from the path the wrong loadjsnirf

Thank you for your timely help and your remind. But it seems that the question doesn’t lie here. The path is correct.

What’s more, I downloaded the previous version (updated about 1 years ago) and it could open successfully. In Jan 26 there was a new update but I still can’t open the latest version.

Thanks for verifying that and the feedback. It allow us to pin point the issue

This is now fixed. Commit 0e5a134
Please download again Brainstorm at its latest version: 27-Jan-2026 (260127)
