Hey everyone,
%%To load data from the (.mat) files and then convert them to (.txt) files
a=['20MIN_SCHJ300639_220208.mat' '20MIN_SEMS170640_040608.mat' '20MIN_SIMG200162_060208.mat'];
for i=1:3
fid = fopen('Data%i.txt', 'w');
load('a(i)');
fprintf (fid, '%.9f \r\n', data_block1);
fclose(fid);
end
I'm having an error in load('a(i)')!! How can I make it work?

Make a a cell array of strings:
a={'20MIN_SCHJ300639_220208.mat' '20MIN_SEMS170640_040608.mat' '20MIN_SIMG200162_060208.mat'};
for i=1:3
fid = fopen('Data%i.txt', 'w');
load( a{i} );
fprintf (fid, '%.9f \r\n', data_block1);
fclose(fid);
end

What happens if you only load two files? (do you get data_block1 and data_block2 then?)

I loaded each one of the files separately to find the error!! So, I found 3 files out of the 70 that contain 3 data blocks. I removed them from the cell array and loaded them by themselves. I also found another error in the way I wrote my cell array, I fixed it and finally it worked properly!!
