I collected the raw data from a Raman image which acquired 140 Raman spectra from a 14X10 rectangular area. The resulting data file contains 281820 rows for all the spectra so how should I restore the 140 individual data files?

Use reshape
data = (1:281820)';
cols = 140;
rows = numel(data) / cols;
data_reshaped = reshape(data, [rows cols]);
whos
Also, if you are just getting started with Matlab, I would highly recommend that you take a couple of hours to go through the free online tutorial: Matlab Onramp
