Hi Christine,
Daniel and I did some thinking about this.
The short (but surely unsatisfactory) answer is that
your command :
adwarp -apar Ax_T1_SPGR+tlrc -dpar ROIs+acpc -prefix ROIs
applies the ORIG to TLRC transformation to the ACPC
dataset. The adwarp program does not somehow figure
out that the ACPC is at a halfway point. That is to say,
it does not do anything special about ACPC vs. ORIG
input.
So that leaves some pondering of options like:
- try to check for this situation and apply just the needed
part of the transformation within adwarp
- come up with an alternate way to transform the data
(there are a few possibilities here)
- start with points in the ORIG space data
Exactly what was your method for populating the
datasets with those points?
