Question

我有无数文件夹需要访问并删除其中的前6个文件。目前，我有一个代码进入该文件夹，并一次删除一个文件。我似乎无法弄清楚如何创建一个循环来简化这段代码。

FN_NIFTI = 'C: path';
funcdir = 'C: path'/folder';
FNruns = {'Folder 1', 'Folder 2', 'Folder 3', etc..};

for i=1:length(FNruns)
    delete(fullfile(FN_NIFTI,funcdir,FNruns{i},'*001.nii'))
    delete(fullfile(FN_NIFTI,funcdir,FNruns{i},'*002.nii'))
    delete(fullfile(FN_NIFTI,funcdir,FNruns{i},'*003.nii'))
    delete(fullfile(FN_NIFTI,funcdir,FNruns{i},'*004.nii'))
    delete(fullfile(FN_NIFTI,funcdir,FNruns{i},'*005.nii'))
    delete(fullfile(FN_NIFTI,funcdir,FNruns{i},'*006.nii'))
end

请注意，上面的代码会被复制/粘贴多次。例如，我在其下面有另一个代码，例如：

ASL_NIFTI = 'C: path';
funcdir = 'C: path'/folder';
ASLruns = {'Folder 1', 'Folder 2', 'Folder 3', etc..};

for i=1:length(NWruns)
    delete(fullfile(ASL_NIFTI ,funcdir,ASLruns {i},'*001.nii'))
    delete(fullfile(ASL_NIFTI ,funcdir,ASLruns {i},'*002.nii'))
    delete(fullfile(ASL_NIFTI ,funcdir,ASLruns {i},'*003.nii'))
    delete(fullfile(ASL_NIFTI ,funcdir,ASLruns {i},'*004.nii'))
    delete(fullfile(ASL_NIFTI ,funcdir,ASLruns {i},'*005.nii'))
    delete(fullfile(ASL_NIFTI ,funcdir,ASLruns {i},'*006.nii'))
end

我很感激帮助！（请给初学者解释）

你可以从改善for循环开始。

for i = 1:length(targetFolder)
    for fileNr = 1:6
        delete(fullfile(targetFolder{i}, sprintf('*00%d.nii', fileNr)));
    end
end

变量targetFolder应包含您要删除文件的所有文件夹。如果以特殊方式选择了theese文件夹，您可以将它们排成一行：

targetFolder = { ...
   fullfile(FNrunsRootDir, FolderA), ...
   fullfile(FNrunsRootDir, FolderC), ...
   ...
   fullfile(ALSrunsRootDir, FolderX), ...
   fullfile(ALSrunsRootDir, FolderY), ...
   ...
};

如果 all 应该挑选每个根文件夹中的子文件夹，您可以使用dir来获取它们

rootDirs = {FNrunsRootDir, ALSrunsRootDir, ...}

for iDir = 1:length(rootDirs)
    subDirs = dir(rootDirs{iDir});
    % Pick out all valid sub folders
    subDir = setdiff({subDir([subDir.isdir]).name}, {'.','..'});
    % Combine into full folder paths
    targetFolder = strcat(rootDirs{i}, filesep, subDir);

       %%%% FOR LOOP FROM ABOVE GOES HERE %%%%

end
