Hello,

I am new to matlab and I am having issues using my cell array in a for loop. I have a cell array called "uni_path_list" (1x35) containing paths to folders where my image files are located. For each loop I am trying to convert the dicom files within a folder to the nifti format. When I run the code I receive no errors, but my image files do not convert. Instead I find that "hedr" is empty (0x0 cell), but "files" is, for example, a 34x72 character array containing image names within a specific folder.

for i = 1 : length(uni_path_list)
    files = spm_select('List', uni_path_list{i});
    hedr = spm_dicom_headers(files);
    spm_dicom_convert(hedr);
end
%An example file path:
%/Users/SC/Desktop/Project/MR/Test/REMIND_001/MR_HEAD_20000213_172316_000000/3_PLANE_LOC

Thank you in advance!

yes，sir，may be check the file，such as

for i = 1 : length(uni_path_list)
    files = spm_select('List', uni_path_list{i});
    if exist(files, 'file')
        hedr = spm_dicom_headers(files);
        spm_dicom_convert(hedr);
    else
        disp(files);
        disp(['can not find this file, please check it']);
    end
end
%An example file path:
%/Users/SC/Desktop/Project/MR/Test/REMIND_001/MR_HEAD_20000213_172316_000000/3_PLANE_LOC

Thank you so much for your reply. When I run this code it does say that it cannot find the files. The folder and all of its subfolders are in the Matlab path, so how would I go about fixing this?
