Concatenation of nested cell in one array and writing in text file

How do I rearrange a 8x1 nested cell into one long cell array (variable attached). Each (from 8) cell includes 2x1 cell. My goal is twofold:

1. saving the of the 8x1 nested cell in a cell array
2. writing the unnested cell array to a text file

Thanks!

Data = load('nestedCell.mat');
C = cat(2, Data.nestedCell{:});
FID = fopen('YourFile.txt', 'w');
fprintf(FID, '%-8s%g\n', C{:});
fclose(FID)

fprintf(FID, '%-8s%g\n', C{:});

I understood everything except this part: '%-8s%g\n'. What does 8 mean? If it means the number of cells in the original nested array, how I can change my code in case if do not know how many cells the nested array conatins.

Try it:

fprintf('*%-8s*\n', 'asd')

*asd     *

fprintf('*%8s*\n',  'asd')

*     asd*

The 8 is the number of chars reserved for the output. With - the string is moved to the left, without - to the right. So this is only to have a nice formatted output. See:
