fid = fopen('JPCLN001.img','r','b');
oneSlice = fread(fid, [2048 2048], '*uint16','b');
img = mat2gray(oneSlice, [0,4096]);
imshow(img);
fclose(fid);

I have this code for conversion. But i want to permenantly save this image. Is that possible?

im8 = im2uint8(img);
imwrite(im8, 'OutputFileName.png')
