I’m currently using the ‘fat_proc_imit2w_from_t1w’ function to convert T1ws to imitation T2ws for DIFFPREP structural registration. Reading AFNI helpfile for the function explains:
NB: if you use a volume made this way as a reference in TORTOISE, then at least for ~adult-human-like (imitation) t2w volumes, at present it seems like you should use the option: --enforce_deformation_antisymmetry 1 This seems to improve registration.
However, when I try to run the command with this option…
fat_proc_imit2w_from_t1w -inset T1_proc/anat.nii.gz -mask T1_proc/anat_brain.nii.gz -prefix T1_proc/anat_t2w --enforce_deformation_antisymmetry 1
I get the following error:
** unexpected option #7 = '--enforce_deformation_antisymmetry'
As of this moment (5:30pm on 2017-10-06), I have the most up-to-date binaries. Any ideas for why this option is unexpected?
