Hello.

How can you avoid overwriting data in struct? Data struct now only provides data of last file in EMG. Normally there are 6 files of EMG. How can I put all of them in a struct?

Thanks.

%% load EMG data
myFolder = 'E:\**\Assignment_V3\Data'
if ~isfolder(myFolder)
    errormessage = sprintf('Error: The folder does not exist'); 
    myFolder = uigetdir();
    if myFolder == 0 
        return;
    end 
end 
filePattern = fullfile(myFolder, '**/EMG/*.mot'); 
pathway = dir(filePattern); 
for k = 1:length(pathway) 
    EMGfile = pathway(k).name;
    EMGcorrectfile = fullfile(pathway(k).folder, EMGfile);
    fprintf(1, 'Now reading %s\n', EMGcorrectfile); 
   EMGdata = importdata(EMGcorrectfile);
end

在 MATLAB Online 中打开

Attach 2 different .mot files so we can run your code.

In the meantime, try this untested code:

% Load EMG data
myFolder = 'E:\**\Assignment_V3\Data'
if ~isfolder(myFolder)
    errormessage = sprintf('Error: The folder does not exist'); 
    myFolder = uigetdir();
    if myFolder == 0 
        return;
    end 
end 
filePattern = fullfile(myFolder, '**/EMG/*.mot'); 
pathway = dir(filePattern); 
for k = 1:length(pathway) 
    EMGfile = pathway(k).name;
    EMGcorrectfile = fullfile(pathway(k).folder, EMGfile);
    fprintf(1, 'Now reading %s\n', EMGcorrectfile); 
    EMGdata = importdata(EMGcorrectfile);
    EMGstruct(k).data = EMGdata; % Add a structure to the structure array.
end
