I'm attempting to process data from a folder with multiple text files, I want to take specific rows/columns from said text files and by applying the reshape/mean function I want to process each text file into a new set of data and write it into a new text file.
Files = dir('C:\Users\lukeaskew\Documents\MATLAB\SpineParametersData');
N = length(Files)
% loop for each file
for i = 1:N
thisfile = Files(i).txt;
AvLx = mean(reshape(thisfile(1:168, 2),28, ));
AvLy = mean(reshape(thisfile(1:168, 3), 28, ));
AvHx = mean(reshape(thisfile(179:192, 2), 14, ));
AvHy = mean(reshape(thisfile(179:192, 3), 14, ));
D = reshape(Avx,6,1);
E = reshape(Avy,6,1);
F = reshape(AvHx,1,1);
G = reshape(AvHy,1,1);
H = [D(:), E(:)];
I = [F(:), G(:)];
J = cat(1,H,I)
The issue I am having is that when I print the value of N I get 0 and so the loop does not run through the folder, nor does it ultimately produce the datasets I require.

Adding to Stephen, In order to explore a similar type of example to get a better idea about looping through text files
