Dear All,  
I am trying to register a volume inside another bigger volume, where I know that it should have only translation in Y axis and rotation only to match.  
Here is the screeenshot…

Volumes I am trying to register is uploaded here. (I had to rescal original data to look similar as an image)

[registration - Google Drive](https://drive.google.com/open?id=1iGdQmh-ZAt5W_PE6gtle6kspG-S2iNfb)!

What would be the easy and best way to register this volume ?

Are there markers in this volumes? If yes, you can perform the fiducial registration to repostion them

1. creat two point lists use the markups(F-1;F-2), each list contain at lest 3 points
2. swith to the fiducial registration module and apply the transform matrix

.
