Dear AFNI experts:
I used 3dresample to downsize the slice resolution from 321 slices to 53 slices via -dxyz, specifying 6 x slice thickness. I use "-rmode Linear". Specifically,
3dresample -dxyz 1.042 1.042 3.36 -rmode Linear -prefix ....
I checked the source codes but I was not sure the exact equation.
Is it a simple linear fit over 6 slices with a straight line?
Could someone explain?
I hope to find the exact equation used across the slices at the same XY location.
Thanks.
