I'm having some trouble reshaping a 4D array to a 2D array. Currently the array is follows, (14965, 16, 32, 256). Where 14965 is number of images. I want to save every 2D array in image formate.

Are you trying to output 14965 images of 512 by 256 each?

256 is the number of channels

You appear to want 14965 images output. What size should each saved image be?
Or are you wanting to output 14965*256 = 3831040 image files?

i want 14965 images of size 16*32 but the problem is every image of this size have 256 channel not 3 RGB channel.

Well, then they're not images and you need to find out what these 256 channel represent. Until you do, we can't really help, we certainly have no idea what they are.

Another possibility is that you want to create multichannel TIFF.

I want to merge the 256 channel to one channel RGB image of 16*32

How do you want the merged channels to be calculated?

SliceNumber = 8392; %for example
frame = squeeze(YourArray(SliceNumber, :, :, :));
volumeViewer(frame)
