Absolutely, thanks for looking into this. 

I have 3 datasets:

1. T1 anatomical
2. DTI
3. Unusual dataset (derived from DTI) that does not have a contrast that 
bbregister can use to register the data

I want to register the unusual dataset (#3) to the T1 anatomical.

Since the unusual dataset cannot be read successfully by bbregister, I 
registered the DTI to the anatomical and I would like to use the registration 
parameters from that registration (DTI to t1) to register the unusual dataset 
to the T1. 

Is this a possibility?

    I don't know what you are trying to do. Can you elaborate?
