That command looks right. If the unusual volume was derived in a voxel-for-voxel way from the DTI, then its registration should be just as good On 04/20/2017 12:11 PM, Jacobson, Aaron wrote: > Thanks a lot! That worked well! The registration is not perfect, but it is > much better than the ori

Thanks a lot! That worked well! The registration is not perfect, but it is much better than the original. I used the command: mri_vol2vol --mov PathTo/UnusualData.nii.gz --targ PathTo/orig.nii.gz --interp nearest --o PathTo/UnusualData_toT1reg.nii.gz --reg PathTo/dti2t1.dat Is there anything

Yes, when using mri_vol2vol or mri_vol2surf, spec the unusual data set as the --mov but pass the bbregister registration to the --reg flag. On 04/20/2017 11:41 AM, Jacobson, Aaron wrote: > Absolutely, thanks for looking into this. > > I have 3 datasets: > > 1. T1 anatomical > 2. DTI > 3. Unusual

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 can

I don't know what you are trying to do. Can you elaborate? On 04/19/2017 07:26 PM, Jacobson, Aaron wrote: > Hello, > > I am new to freesurfer. I have been looking for an answer to this > issue for days. > > I ran bbregister to align a dti scan to a t1 struc. > > It worked beautifully. > > I am t

Hello, I am new to freesurfer. I have been looking for an answer to this issue for days. I ran bbregister to align a dti scan to a t1 struc. It worked beautifully. I am trying to register a very abnormal looking dataset to the t1 using the registration parameters created during the first bbre
