Hi everyone,
I'm sorry but I'm getting a little confused about cat_matvec.
I defined two 3x3 matrices A and B, and did
cat_matvec A B > C
and fould C=B*A, which suggests transform A is applied first, and then B is applied.
This is exactly what the doc describes.
So if I'd like to volreg a dset, then align it to anat, I should do
cat_matvec volreg align > combined
3dAllineate -1Dmatrix_apply combined
Is it correct?
But I found the script generated by afni_proc.py seemed to do the opposite:
cat_matvec align volreg > combined
How to understand the order of operation during xform concatenation?
Thanks very much!
