[Freesurfer] Error in preproc-sess in ver. 5

Hi all,

While attempting to pre-process data for a retinotopy analysis with the following command:

preproc-sess -surface song lhrh -fwhm 5 -sf sessid

I get the following error when motion correction is started:

Logfile is /Users/andershougaard/Programmer/freesurfer/retinotopy/log/mc-sess01-bold.log ------------------------------------------- /Users/andershougaard/Programmer/freesurfer/retinotopy/sess01 RunList: 001 002 ------- ************************** ----------- ------- Motion Correcting Run 001 ----------- ------- ************************** ----------- sess = sess01 Lør 2 Jul 2011 11:59:31 CEST mc-afni2 --i 001/f.nii --t 001/template.nii --o 001/fmcpr.nii --mcdat 001/fmcpr.mcdat ERROR: cannot find AFNI command 3dvolreg

Any suggestions?

Regards,

Anders
