Trouble with tutorial artifact correction

Bugs

Hi Brainstorm Team,

I'm new to Brainstorm, working my way through the tutorials. When trying to use artifact correction to detect heartbeats and/or blinks (Tutorial 12), I received the following error.

I'm guessing this is human error, but I'd greatly appreciate any assistance the team might be able to offer (also happy to provide any other required info to assist with this).

Macbook Pro running Sierra (10.12.6). Matlab version R2014b

Thanks so much in advance.

Best,
Jason

Hi Jason,

Do you have other Matlab toolboxes installed on your computer?
Make sure that you don’t have any function that shadows the original Matlab functions firls.m and fir1.m in your path.

In your Matlab command window, type “which firls” and “which fir1”. This shows the path from which the functions are executed. If any of the path is not in your Matlab Signal Processing Toolbox installation folder (eg. …/MATLAB/R2014b/toolbox/signal/signal/), there is something wrong with your path. Remove the corresponding path from your Matlab path and try again.

Cheers,
Francois
