Dear,

I am conducting oblique correction for EPI data in resolution of 3.125x3.125x4.50 with 3dWarp, which coming out an image in resolution of 3.125x3.125x3.125. I'm curious of whether this upsampling is alright cause it may involve more noise relative to downsampling? am i right?

To put it a general word, are there any principles we can rest on when we need to conduct resampling? Are there any limitations?

Best wishes,
Peng
