Hi everyone,

I had a question about transforming between talairached and original space -

I have a talairached anatomical dataset, complete with its +orig and +acpc .HEAD files. I also have a set of ROI's, drawn by another lab on their own anatomical dataset and transformed to talairach coordinates.

I was wondering if there was a way to take these roi's made on a different anatomical and currently in talairached space and reverse transform them so that they will align with my +orig anatomical dataset. The ROI dataset and my anatomical dataset align perfectly in talairach space, but I have tried using:

3drefit -apar [my hires ] [ ROI ]
adwarp -apar [my hires +orig] -dpar [ROI + tlrc]

and the ROI dataset does not seem to budge and is resultantly wildly off from my +orig dataset.

Any pointers?

Thanks!

Arul
