Yes, but you have to get it started in about the right place.

Hi Sebastien

I believe that Doug has had success using bbregister for this. You might give it a try

Cheers

Hi Sebastien,

Robust register cannot register a slice into a 3D volume. It can only register 3d to 3d (or 2d to 2d, although that has not been tested much).

Sorry,

Martin

Hello,

I am trying to register a full volume to a single slice, and I
follow example 3 of mri_robust_register's help. I get the
following error:

 Input image is smaller than min dimension: 1 < 16

 Input dimensions (after conformalizing) MOV: 64 64 64

 Input dimensions (after conformalizing) DST: 64 64 1

 Specify larger minimum ...

This error stays after adding --minsize 1 or --minsize, despite
mri_robust_register recognizing the flag, as suggested by this
terminal output:

--minsize: Smallest dimension > 0 .

Registration ran ok when replacing the single-slice with a
40-slice volume.

Any idea on what is going on here?

Thanks a lot for the good work and

Have a good day!

Sebastien
