Hello,
I have a few hundred text files in a folder, and I want to import and organize all of them within MATLAB. The files are all the same format, but each indivdual file is unique in representing a specifc subject and day of an experiment. For previous analysis of each file I have been using this code to format and organize the data into a structure within MATLAB:
clear
clc
[file, path] = uigetfile('*.txt','Choose Subject 1','default.txt');
txt_file = fullfile(path,file);
[fid,msg] = fopen(txt_file,'rt');
assert(fid>=3,msg)
out = struct();
while ~feof(fid)
pos = ftell(fid);
str = strtrim(fgetl(fid));
if numel(str)
spl = regexp(str,':','once','split');
spl = strtrim(spl);
if isnan(str2double(spl{1}))
fnm = strrep(spl{1},' ','');
val = str2double(spl{2});
if isnan(val)
out.(fnm) = spl{2};
else
out.(fnm) = val;
end
else
fseek(fid,pos,'bof');
vec = fscanf(fid,'%*d:%f%f%f%f%f',[1,Inf]);
out.(fnm) = vec;
end
end
end
fclose(fid);
Subject1 = out;
clearvars -except Subject1
I was wondering if there was a way to create a loop where the code would run through however many files are in my folder and organize each file into their own structure array? I attached 3 example files, but they are not within a single folder. I am specifcally looking for help creating a loop that would go through an entire folder of these files without manually clicking on each file. Any assitance is really apprecaited, thanks.

datapath=uigetdir([],'Select Data Directory');
d=dir(fullfile(datapath,'*.txt');
for i=1:numel(d)
txt_file = fullfile(datapath,d(i).name);
...
end
