Hi,
I am trying to run the mff_import funchtion for my EEG data. I am also loading the EEGlab package as well.
Here is my code:
eeglab
folderRaw = 'mary_20220401_010203.mff';
EEG = mff_import(folderRaw);
Here is my error(with code):
>> folderRaw = 'mary_20220401_010203.mff';
>> EEG = mff_import(folderRaw);
Error using mff_importsignal
Error: Can not open the signal resource.\n
Error in mff_import (line 85)
[floatData, allDataSize, srate, nchans] = mff_importsignal(mffFile);
This was working for me before but now has stopped working. Does anyone know why I am getting the following error and how I can fix it?

Hi Mary,
Given that the error has occurred unexpectedly, it would be advisable to start by checking the integrity of the ".mff" file you are attempting to import. If possible, please try importing a different ".mff" file that you have successfully used in the past. This step will help determine if the problem is isolated to the specific file.
If the problem still persist, it may be beneficial to explore alternative tools for importing your data. One such tool is the "FieldTrip" toolbox, which provides comprehensive methods for analyzing MEG, EEG, and other types of electrophysiological data. You can find more information about the toolbox in the link provided below:-

I hope it helps.
