External Email - Use Caution
It is group level, result of 2nd-level analysis. I preprocessed data of 50 subjects with FSFAST and SPM respectively, then I used SPM to do the 1st- and 2nd-level modelling. The version of FS now I use is 6.0 I think: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c.

External Email - Use CautionDear Freesurfer experts,
Now I am using both FSFAST and SPM to preprocessed my functional image data. In FSFAST, I replaced the subcortical template with the whole brain in the folder "mri.2mm", to get the whole brain volumetric data. I have also diluted the whole brain template in FSFAST. However, as showed in attached files, the resampled data in FSFAST seems smaller than that of SPM. May I ask if it is normal? Would the mask creation step in FSFAST caused this difference? I read from a previous PPT which said "FSL BET run on the template" in mask creation. As far as I know, the default parameter in BET may strip some part of prefrontal lobe sometime. If FSFAST apply BET or similar algorithm to strip skull, may I ask how could I change the parameter? Looking forward to your kind suggestions.
Thanks and best wishes,
Lizhi
