fprintf \n not working properly

Hi all, im trying to print out some data into a specific format so it can be read into another program. The code i am enacting centers around this loop:

%Write section data

for i=1:nsections

    fprintf(fileID2,'SECTION %1.0f\n',i);
    row_start_index = 1 + (i-1)*54;
    for j=1:npoints
        row_index = row_start_index+(j-1);
        fprintf(fileID2,'%12.8f %12.8f %12.8f %12.8f %12.8f \n',Data(row_index,1),Data(row_index,2),Data(row_index,3),Data(row_index,4),Data(row_index,5),Data(row_index,6));
    end
end

The output should look like (ignore the 1. 2. 3. 4. ... some forum formatting thing)

Section 1

1. # # # # #
2. # # # # #
3. # # # # #
4. # # # # #

Section 2

1. # # # # #
2. # # # # #
3. # # # # #
4. # # # # #

and so on

but actually what i get is this:

Section 1

1. # # # #
2. # # # # #
3. # # # # #
4. # # # # #
5. #Section 2
6. # # # #
7. # # # # #
8. # # # # #
9. # # # # #And so on..

it appears everything is shifted over by 1 number somehow.

I should mention i have played with /r/n and opening the file with the "wt" command

Anyone know why this is happening?

Any help would be greatly appreciated !

Thanks

You are printing a 5 column row:

'%12.8f %12.8f %12.8f %12.8f %12.8f \n'

but supplying 6 datatpoints:

Data(row_index,1),Data(row_index,2),Data(row_index,3),Data(row_index,4),Data(row_index,5),Data(row_index,6)

which you can write as

Data(row_index,1:6)

fprintf(fileID2,'%12.8f %12.8f %12.8f %12.8f %12.8f %12.8f\n',...         
        Data(row_index,1:6));

Or

fprintf(fileID2,'%12.8f', Data(row_index,1:6));
fprintf(fileID2,'\n');

thank you, i am an idiot

Well, I wouldn't say that. Everyone make simple mistakes sometimes.
