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,
