That means that geometry information (ie, what is left and right, anterior or posterior) is not part of the nifti file. Without that information, the anatomical analysis cannot be done. You will either have to fix it yourself (ie, imbed that info into the file) or, better, recreate the file wit

Dear Experts, according to the log, Vasudev is using version 5.3-HCP. Therefore I expect that he is running FreeSurfer inside HCP pipeline scripts.  The problem is that the use of 6.0 version with HCP pipeline scripts is not currently recommended. see http://www.mail-archive.com/freesurfer@nmr.
