hi every body. i have a volume which consist of 430 images and the size of each image is 512*512. so the size of the volume is 512*512*430.
because of the large capacity of the volume, i want to select construct the volume with half of the number of images to have the volume of size 512*512*215
and i want to select the odd or even indexes of images.
how can i do that?

Let say Image1 is the original 3D image
resultant_image=image1(:,:,1:2:430)
