Hi Aga, are you using nifti? If analyze, that could be the problem. Do your functionals and anatomicals have a different sign to their determinants (you can check with mri_info). In principle, reg-feat2anat should handle this but in some cases it does not. The 5.1 version will handle it properly. If they do have the same sign, then look through the log file and find the flirt command. Run that command by itself (you may need to run reg-feat2anat with --nocleanup to keep it from deleting the files). If that fails, then contact the FSL people
