dear FS community： now i have many subjects may should rerun in FS6.0 so i thought could i use gpu for accelerating, and through searching in the mailing list i got some messages: 1. cuda was no longer supported 2. new features in cpu version were not add in gpu version as those above, is following example correct? in FS6.0 reconall_table i got this: mri_ca_registerhttps://surfer.nmr.mgh.harvard.edu/fswiki/mri_ca_register -align-after -nobigventricles -mask brainmask.mgz -T transforms/talairach.lta norm.mgz $FREESURFER_HOME/average/RB_all_2016-05-10.vc700.gca transforms/talairach.m3z obviously it is new and different from mri_ca_register in FS5.3, so if i run mri_ca_register_cuda, it cannot get RB_all_2016-05-10.... and then may shutdown or run with the older version. the right gpu now was not setted so i cannot run a test, while i read a letter https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2017-February/049923.h..., that Dr Chris Adamson said gpu version ran sucessfully, which made me confused, dose gpu run the real FS6.0 with so many new features? hope some one can help best regards to you all! weiwei west china hospital ________________________________ weiqi77777@live.com
