     EEG = pop_saveset( EEG, 'M04_ED1' );  
     EEG = eeg_checkset( EEG );

About this above script, I change

EEG = pop_mffimport({'C:\EEG_OVGU\ED1\M01_ED1'},{'code','description','label','mffkeys','mffkeysbackup','name','relativebegintime','sourcedevice','tracktype'}); 

into

EEG = pop_mffimport({'C:\EEG_OVGU\ED1\setname_in'},{'code','description','label','mffkeys','mffkeysbackup','name','relativebegintime','sourcedevice','tracktype'});

Why it does not work? how can I correct it? Thank you very much!

end

I need to change mff.file into set.file. But the script does not work.

The error in the MATLAB is:

Error using javaObject

No constructor with appropriate signature exists in Java class com.egi.services.mff.api.MFFResourceType

Error in mff_importsignal (line 61)

signalresourcetype = javaObject('com.egi.services.mff.api.MFFResourceType', javaMethod('valueOf',

Error in mff_import (line 85)

Yes. the pop_mffimport is work for the single data.

such as

 EEG.etc.eeglabvers = '2020.0'; % this tracks which version of EEGLAB is being used, you may ignore it
     EEG = pop_mffimport({'C:\EEG_OVGU\ED1\M01_ED1'},{'code','description','label','mffkeys','mffkeysbackup','name','relativebegintime','sourcedevice','tracktype'});
     EEG = pop_saveset( EEG, 'M01_ED1' );  
     EEG = eeg_checkset( EEG );
          EEG.etc.eeglabvers = '2020.0'; % this tracks which version of EEGLAB is being used, you may ignore it
     EEG = pop_mffimport({'C:\EEG_OVGU\ED1\M03_ED1'},{'code','description','label','mffkeys','mffkeysbackup','name','relativebegintime','sourcedevice','tracktype'});
     EEG = pop_saveset( EEG, 'M03_ED1' );  
     EEG = eeg_checkset( EEG );
     
          EEG.etc.eeglabvers = '2020.0'; % this tracks which version of EEGLAB is being used, you may ignore it
     EEG = pop_mffimport({'C:\EEG_OVGU\ED1\M04_ED1'},{'code','description','label','mffkeys','mffkeysbackup','name','relativebegintime','sourcedevice','tracktype'});
     EEG = pop_saveset( EEG, 'M04_ED1' );  
     EEG = eeg_checkset( EEG );

but I want to warite a loop to run them at the same time. It does not work.

My MATLAB version: R2020a, EEGLAB version: v2020.0

Okay, but I need the answer to what I asked above:

If your line

     EEG = pop_mffimport({'C:\EEG_OVGU\ED1\M01_ED1'},{'code','description','label','mffkeys','mffkeysbackup','name','relativebegintime','sourcedevice','tracktype'});

works for you, and if executing the line a second time also works for you (sometimes there are problems that only occur the second time you do something), then please put in a breakpoint at the beginning of the line

     EEG = pop_mffimport({fullfile('C:\EEG_OVGU\ED1',setname_in)},{'code','description','label','mffkeys','mffkeysbackup','name','relativebegintime','sourcedevice','tracktype'});

and when you stop at the breakpoint, ask to display

{fullfile('C:\EEG_OVGU\ED1',setname_in)}

and copy and paste the result here for us to look at.

Then in the editor window, click on the "Step" button to have it execute that line. Does it fail the first time through? If not, then continue running, stopping at that line each time and displaying

{fullfile('C:\EEG_OVGU\ED1',setname_in)}

before Step, and tell us how many of the calls to pop_mmfimport work and tell us which file it fails for.

Thank you so much for your help!!!!!!

I set a breakpoint, but MATLAB isn't stopping at the breakpoint.

In addition, I don't see the Step button in the editor.
