Hi Mark,
The mask is already registered to ref image. I changed the config file as you
said and I am running the fnirt command using it. But it takes more than 15
hours to be run. I used to use --subsample 4, 4, 2, 2 before to decrease the
run time. But, in the new config file when I want to change the subsample line
to speed up fnirt, it seems that I should also change the miter line. I couldn't
change it because I don't know its relation to miter parameter. If there is a
setting for speed it up, please let me know.
