Good day all,
I have 25 subfolder each contains some text files. I developed a loop that runs through the text files in a sub folder, extract some vaules from each text file and perform some calculations. Is there any way i can modify my code to run through all the the sub folders at the same time? I want the loop to execute my script (see the script below) for each sub folder and save the results ('Displacement') before proceeding to the next subfolder. So i am expeting to have Displacement1, Displacement2, ..Displacement25 as the final outcome.
x = []; y = []; z = [];
files = dir('*.xvi');
for k = 1:length(files);
fid = fopen(files(k).name,'r');
while ~feof(fid)
st = fgetl(fid);
if ~isempty(strfind(st,'CouchShiftLat'))
stread = textscan(st,'%s %f','Delimiter',';=');
x = [x; stread{2}(1)];
elseif ~isempty(strfind(st,'CouchShiftLong'))
stread = textscan(st,'%s %f','Delimiter',';=');
y = [y; stread{2}(1)];
elseif ~isempty(strfind(st,'CouchShiftHeight'))
stread = textscan(st,'%s %f','Delimiter',';=');
z = [z; stread{2}(1)];
end
end
fclose(fid);
end
Displacement=[x,y,z];

mainfolder = uigetdir;
subfolders = dir(mainfolder);
subfolders = subfolders([subfolders.isdir] & ~startsWith({subfolders.name},'.'));
for i = 1:length(subfolders)
x = []; y = []; z = [];
files = dir(fullfile(mainfolder,subfolders(i).name,'*.xvi'));
for k = 1:length(files);
fid = fopen(files(k).name,'r');
while ~feof(fid)
st = fgetl(fid);
if ~isempty(strfind(st,'CouchShiftLat'))
stread = textscan(st,'%s %f','Delimiter',';=');
x = [x; stread{2}(1)];
elseif ~isempty(strfind(st,'CouchShiftLong'))
stread = textscan(st,'%s %f','Delimiter',';=');
y = [y; stread{2}(1)];
elseif ~isempty(strfind(st,'CouchShiftHeight'))
stread = textscan(st,'%s %f','Delimiter',';=');
z = [z; stread{2}(1)];
end
end
fclose(fid);
end
Displacement=[x,y,z];
% save here
end

yes, put this inside the subfolder loop.
Displacement=[x,y,z];
matfile = fullfile(mainfolder,subfolders(i).name,'output.mat');
save(matfile,'Displacement')
