Dear Members,
I have the following text file which I want to manipulate. Currently the data looks like this:
Set-1,2E-01,13.23,93.90,49,-9,0,0,20,33,74,-9,0,0
Set-2,2.21E-01,19,194,39,1,0,0,-19.7823,28.9842,78.3404,-7,0,0
I want to change it to the following format (Note- The last 6 numbers are now placed on the next line and no comma at end of first line):
Set-1,2E-01,13.23,93.90,49,-9,0,0
20,33,74,-9,0,0
Set-2,2.21E-01,19,194,39,1,0,0
-19.7823,28.9842,78.3404,-7,0,0
Could you please show me how this can be done in Matlab.

S = fileread('example.txt');
C = strsplit(S, '\n');
for iC = 1:numel(C)
aC = C{iC};
comma = strfind(aC, ',');
aC(comma(end - 5)) = char(10);
C{iC} = aC;
end
fid = fopen('Output.txt', 'w');
if fid == -1, error('Cannot open file for writing'); end
fprintf(fid, '%s\n', C{:});
fclose(fid);
