Hi,
I have a 4D data set A(m,n,j,k). In a for loop the data is "squeezed" into a cell A_cell to make k 3D cell entries each A_cell{k} = A(m,n,j). Each cell entry is saved as a .mat in the home directory within the loop.
Now in the loop(or not), I need to open either each cell or each saved .mat file, generate j tif images for each of the cell/.mat entries/files, and then save these images as tiff with numbered names back into the home directory.
I am using this function to generate ImageJ-readable images from the 4D data sets.
Can somebody please help with this?
Thanks!

Should be very easy with this http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F and this http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F. Inside the loop, create an outputfilename with sprintf() and fullfile (like the FAQ shows) and then get the image from the cell array with braces
thisImage = myCellArray{index};
Then call imwrite
baseFileName = sprintf('..........
fullFileName = fullfile(folder, baseFileName);
imwrite(thisImage, fullFileName);

I would use sprintf but include the Step part:
file_name = sprintf('Frame_%d, Step_%d.tif', k, i);
It looks simpler to me and more like other languages you're familiar with like C and Java.
