Robert, I can understand how this works if K is a constant time value but in my case K varies at each location in the two-dimensional slice. In other words, if I was doing this in a for loop I would do something like this for i in range(numI): for j in range(numJ): k = slice(i,j)

Greetings, I have an I,J,K 3D volume of amplitude values at regularly sampled time intervals. I have an I,J 2D slice which contains a time (K) value at each I, J location. What I would like to do is extract a subvolume at a constant +/- K window around the slice. Is there an easy way to do thi
