How much of this process do you have so far? Is there a specific issue you're running into, or not sure how to do any of it in Matlab?

hello
I believe this code should work - I tested it only with loops = 2 even though I think you need to go up to 120
data = importdata('el.txt');
[m,n] = size(data);
loop = 2
% option 1 : split and save as separate files
for ci = 1:loop
ind = ci:120:m;
data_out = data(ind,:);
filename = ['data' num2str(ci) '.txt'];
writematrix(data_out, filename);
end
% option 2 : or stack vertically and save as one files
data_all = [];
for ci = 1:loop
ind = ci:120:m;
data_out = data(ind,:);
data_all = [data_all;data_out];
end
filename = ['data' num2str(ci) '.txt'];
writematrix(data_all, 'data_stacked.txt');
