Dear all,
we are trying to normalise T2 images to the ICBM DTI template (to the B0 image, which is a T2 image) using SPM8 or SPM12b. In particular we need the inverse and forward normalisation parameters going between each of the T2 images and the template, not the normalised images per se.
Is it possible to define the template to which your images are normalised in either of these SPM versions? The default template is in T1 contrast, which is not optimal for our case.
We've considered registering the T1 images to the T2 and then normalising and obtaining the parameters like that, which is however not what we need: we need the parameters going back and forth between the T2 scans and the ICBM Template.
Alternatively we've considered running DARTEL on the T2 scans, which would create a template for us that we could then register (affine) to the T2-Template we're interested in. However for this step we're not sure how well the initial import steps needed for DARTEL works on T2 scans, does anyone have any suggestions?
So, all in all, the best, most direct method for us would be to have direct transformations between T2s and the ICBM T2 Template. We would like to avoid having multiple steps and having to concatenate multiple normalisation parameters and affine transformations to get from one point to the other.
Thanks for your help!
Miguel.
