Hello!
IŽd have a question about running BET on 4D EPI-volumes in the
preprocessing stage. I have done it in two different ways;
1) run BET on the noise-reducted 4D EPI-volume (resulting in
my_experiment_susan_brain.hdr) before entering it to FEAT and then
select "no BET" in the pre-stats options
or
2) feed my_experiment_susan.hdr to FEAT and select BET in the pre-stats
options
At least with my data way 1) seems to be more effective in skull stripping
than way 2) but I`m worried whether there a danger of loosing also brain
voxels by "betting" the 4D volume separately prior to FEAT analysis?
Thanks to you and your xtremely useful website!
