Hi All,

I have two sequential data sets I want to compare. So I'd like to do some inter and intra registrations. The first is T2-weighted (DATA1), and the second is T1-weighted (DATA2), so different contrast. I am trying to work on the registration and I think I've progressed decently but there's one part I would appreciate some guidance on, please.

I've registered the first data set with the following command:

>> 3dvolreg -twopass -twodup -cubic -dfile Data1_RegParam -prefix Data1_Reg Data1+orig

So I've saved the motion parameters to 'Data1_RegParam'. Now, I'd like to use the motion parameters from the last BRIK in DATA1 and use it to move the first BRIK in DATA2 (inter-registration). Then I can perform an intra-registration of DATA2 with the same command as above.

QUESTION: My question goes to the inter-registration part. How do I use the values of the motion parameters (below is what I get in my 'dfile') to move a BRIK in another data set? Please let me know if my questions doesn't make sense and I can aim to clarify.

Thank you in advance for any and all help.

Cheers,
Edwin
