Hi John,

I think 'Reset' will abort all transformations applied to the images.
Is there any way to abort the last transformation only?

For example, I coregistered a MRI to a mean PET image after rotating the MRI with Display (rotation and change of origin).
I wonder if one can abort only coregistration.

Thank you,

Buyean

You can't revert back to the original orientation from the DICOM headers, but 

you can reset the orientations via the Display button.  Display one of your 

images, and click the Reset button in the graphics window.  Then select all 

the images that you want to have reset.



The ``Reset...'' button is for setting the orientation of images back to 

transverse.  It retains the current voxel sizes, but sets the origin of the 

images to be the centre of the volumes and all rotations back to zero.



Best regards,

-John
