In article http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/SkullStripFix, it is mentioned that talairach_with_skull_2.lta is created during autorecon2, and that it can be useful when troubleshooting skull-strips, however I do not find talairach_with_skull_2.lta in the mri/transforms directory of any of my subjects.  Has the processing been altered since the creation of this article or is my data incomplete? If incomplete, why?
