Problem with two-pass normalisation

The standard aa normalisation routine ([http://imaging.mrc-cbu.cam.ac.uk/imaging/AutomaticAnalysisVersions#head-20f22d73e91b461dcf6bf69e792269bdce21ecf4 Automatic Analysis normalisation with segment]) may fail in certain cases. The example below illustrates it: at the bottom, the normalised brain on the left is smaller and has not been reoriented correctly.

In order to allow monitoring of such occurrences, please mail to imagerstech@mrc-cbu.cam.ac.uk if you notice this problem.

Our solution: For this participant, we used the SPM normalize procedure instead of the aamod_norm_noss and rewrite modules.
