Find string inside a cell array
显示 更早的评论
Hi everyone!
I have a variable called filenames (cell array), which will store a random number of files, and PasteInfo2 (cell array), which stores all the files. I want to store the name of the file that matches between in thisfile and PasteInfo2 into the variable name. I already have this portion of code but still can't store the name of that file...
How can I do that?
PasteInfo2 = dir('D:\ABIDEdataset\Outputs\dparsf\nofilt_noglobal\rois_aal\All_Groups');
PasteInfo2_names = extractfield(PasteInfo2,'name');
NumberSubjs = length(filenames):
for i=1:NumberSubjs
thisfile = filenames{i};
if contains(thisfile,PasteInfo2_names)
name = %name of file that is suppposed to be in thisfile;
end
end
Thanks in advance!

Skip the loop and use ismember:
S = dir('D:\ABIDEdataset\Outputs\dparsf\nofilt_noglobal\rois_aal\All_Groups');
C = extractfield(S,'name');
X = ismember(filenames,C);
out = filenames(X)

Try this:
[ia1, ib1] = ismember(filenames,C);
[ia2, ib2] = ismember(C, filenames);
Take whichever variable (ia1, ib1, ia2, ib2) gives you what you want.

Do you want to get the filenames something like this:
folder = 'D:\ABIDEdataset\Outputs\dparsf\nofilt_noglobal\rois_aal\All_Groups';
filePattern = fullfile(folder, '*.*');
% Get a list of all files in the folder.
PasteInfo2 = dir(filePattern)
% Extract just the filenames into its own cell array.
PasteInfo2_names = {PasteInfo2.name}
numberOfSubjects = length(PasteInfo2)
% Loop over all files.
for k = 1 : numberOfSubjects
thisFullFileName = fullfile(folder, PasteInfo2_names{k});
fprintf('Reading %s...\n', thisFullFileName);
% if contains(thisfile,PasteInfo2_names)
% name = %name of file that is suppposed to be in thisfile;
% end
end
