After unwarping oblique EPI images with ppge AFNI briks came out up side down. How can I prevent this?

This problem occurs because the bxh tools that convert data to an intermediate format (ANALYZE) can not handle correctly oblique slice stacks that are acquired in the S-I direction. (NOTE: ppge2 does not use bxh tools and should therefore get around this issue). In that case the conversion results in the following error message: Converting bxh to ANALYZE WARNING: not a supported Analyze orientation -- labeling as transverse unflipped (0) anyway... The flipping of the oblique slices (rotated along the axis perpendicular to saggital plane) can be prevented by the following slice prescription procedures: --rotating slices counterclockwise (slice angle > 180 deg) and dragging mouse UPWARD to add slices.

--rotating slices clockwise (angle.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
