Automatisation for reading, treating and saving .txt files in a directory folder.

Hello everybody,

I have a directory with two folders: one folder contain several subfolders with multiple .txt files (folder 1). The second folder contains several . hjson files (folder 2). I would like load each .txt and hjson files make a several calculation (e.g. velocity, acceleration...) and save a new .csv file in another directory folder in the PC with the same name of the .txt files but adding ‘done’ or ‘treated’. So far, have two code one to load .txt files and another that add the header and save but without changing the name automatically. My goal is to make a code that reads, loads, computes and save automatically in a different folder (). Please let me know if you have any suggestion about.

%% Read and load dir_to_search = 'C:\Programs\pedro\Test\';

txtpattern = fullfile(dir_to_search, '*.txt');

dinfo = dir(txtpattern);

for K = 1 : length(dinfo)

thisfilename = fullfile(dir_to_search, dinfo(K).name);  %just the name

thisdata = load(thisfilename); %load just this file

End

%% %% Adding Headers to the Matrix

headers={'Timestamp','PosX','PosZ','PosY','RotX','RotY','RotZ','RPosX','RPosZ','RPosY','RRotX','RRotY','RRotZ','velocity','acceleration','curvature','distance','target_reached'};

fmt = repmat(',%.12g',1,size(data,2)); % pick numeric format to suit!

fmt = [fmt(2:end),'\n'];

[fid,msg] = fopen('output1.csv','wt');

assert(fid>=3,msg)

fprintf(fid,'%s',headers{1})

fprintf(fid,',%s',headers{2:end})

fprintf(fid,'\n')

fprintf(fid,fmt,data.')

fclose(fid);
