If the number of header lines in the various sections of your file are all the same, something like this should work (it has for me in the past):
fidi = fopen('aneps Big_Text_File.txt', 'rt');
k1 = 1;
while ~feof(fidi)
data{k1} = textscan(fidi,'%f%f%f%f%f', 'HeaderLines',9, 'Delimiter',' ', 'CollectOutput',1);
fseek(fidi, 1, 0);
k1 = k1 + 1;
end
fclose(fidi);
The various sections will be in various cells of ‘data’, and may be different sizes, so you can save each to a separate text file later. Make appropriate changes in the textscan call for your data.
Note: Your file has to have a valid end-of-file indicator or my code becomes an infinite loop. In that event, I need to see the file to figure out an appropriate way to find an end to it.
