Nameeta,

The problem is that SPM's Talairach is not quite Talairach, call it 'MNI system' for now. For a detailed exposition of this issue look at : [www.mrc-cbu.cam.ac.uk] . If you used the SPM template for normalization, the "Where am i" function will work poorly in some areas.

The templates being distributed with AFNI have been modified from the 'MNI system' to conform with the original Talairach system.

You don't need to rerun the normalization and reprocess all your data as long as you realize what space you are operating in. AFNI does allow you some flexibility in dealing with MNI coordinates (for example: 'Jump To' works with MNI coords) but for full compatibility with things like the Talairach Daemon database (Lancaster, Woldorff et al. 2000) included with AFNI it is best you stick to the Talairach, not the MNI system.

Not my fault, I swear.
