Hi Miguel

no, -qcache shouldn't change anything. It just runs some additional steps to map various measures to the fsaverage space (and smooth them at preset levels)

cheers

        External Email - Use Caution        


Hi FreeSurfer devs,

Is there any difference bet

I ran the recon-all several participants (using the command recon-all -subjid 
-all) and I want to
out an external analysis using the volume, area and thickness measures of the 
Destrieux and
Desikan-Killiany atlas. Do these measures suffer any change if I add the qcache 
flag to the command
(i.e recon-all -subjid -all -qcache) or by contrary this flag is only necessary 
when the analysis is
made using QDEC?

I have this doubt because I saw that when I used the -qcache flag, Freesurfer 
make a smoothing of
the images using a FWHM filter of 5,10,12.


Thanks in advance,

Cheers,
