Hi,
I have a csv file and a fits file, I need to select multiple frames from the fits file based on the non-zero indices of a csv file. In the attached csv file, I need to select the 4th and 7th frame from the fits file, as it contains the non-zero values.Can someone help?
TIA

vals = csvread('Book4.csv');
frame_numbers = find(vals ~=0);
num_frame = length(frame_numbers);
frame_data = cell(num_frame,1);
for K = 1 : num_frame
frame_data{K} = fitsread('AppropriateFilenameGoesHere.fits', 'image', frame_numbers(K));
end
