-big_move function

Hello,

I would like to incorporate the -big_move function to help align my epi and anat data better, though I am not sure where I should include this option in my script. Any help is appreciated!

Thank you,
Tamara

It can go most places in the script. I usually put it near the volreg_* steps and before the blur_size. You’ll want to tell the script that it’s an add-on to the align_epi_anat.py by giving it the -align_opts_aea flag first. Example below.


-align_opts_aea -giant_move
