Hi Sebastien

 

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

 

Cheers

Bruce

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,

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
