I don't know why this is happening. I will have to try it myself. I made some changes to 3dQwarp recently, but I cannot imagine which one could cause this effect.

Since it takes a while to run 3dQwarp (as you know), it will be a little while before I can get back. And at this moment, I am in Lucca teaching AFNI, so that will slow things down as well.
