Can you load it with another program?
Did you set correctly the file format to MEG/EEG: Elekta-Neuromag?
Don’t you have any other error message displayed in your Matlab command window before this error?
I can’t load any fif file in brainstorm but they all work well with FieldTrip.
I set correct format and there was no other error message.
But I can load it with another computer(windows) and I use Mac. May be there is some error with my Mac?
The MNE fif reader was recently updated to support new fields such as the one referenced in your error message. You probably have both your own version of MNE-matlab and Brainstorm in your Matlab path at the same time and it is causing conflicts. Try to remove your own MNE-matlab from your Matlab path so that it exclusively uses Brainstorm’s version, or update your MNE-matlab with the latest version.
You would also get the same error if you had multiple versions of Brainstorm in your Matlab path.
Start by cleaning your Matlab path and try again.
Thx! I cleaned my path and it works well now!
