Dear,

I encountered a problem when going from pmod to freesurfer.

I made Vt images in pmod using the logan plot, then I used the following commands to convert them to freesurfer space:

#flirt -noresample -in /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/VT/VT/${word}_Vt.nii -ref /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/$word/mri/T1-2mm_skullstripped.nii.gz -applyxfm -init /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/$word/mri/SUVR/SUV.lrrev_lin_T1.mat -out /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/VT/VT/${word}_Vt.fsl.nii

#3dresample -master /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/$word/mri/occipital.nii.gz -inset /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/VT/VT/${word}_Vt.nii -prefix /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/VT/VT/${word}_Vt.fsl.nii

Then I did partial volume correction using this command:

#mri_gtmpvc --i /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/VT/VT/${word}_Vt.fsl.nii --reg Vt.reg.lta --psf 5 --seg /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/$word/mri/gtmseg.mgz --default-seg-merge --auto-mask 5 0.01 --rbv --o /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/VT/VT/${word}gtmpvc.output.spmreg --no-rescale --threads 8

Then I did surface projection:

#mri_vol2surf --mov /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/VT/VT/${word}gtmpvc.output.spmreg/rbv.nii.gz --reg /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/VT/VT/${word}gtmpvc.output.spmreg/aux/rbv2anat.lta --hemi lh --projfrac 0.5 --o /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/VT/VT/${word}gtmpvc.output.spmreg/lh.mgx.ctxgm.fsaverage.pvc.VT.sm00.proj-0.5.nii.gz --cortex --trgsubject fsaverage

#mri_vol2surf --mov /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/VT/VT/${word}gtmpvc.output.spmreg/rbv.nii.gz --reg /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/VT/VT/${word}gtmpvc.output.spmreg/aux/rbv2anat.lta --hemi rh --projfrac 0.5 --o /autofs/cluster/atassigp/Users/Donatienne/Analyses_freesurfer/recon_flair/VT/VT/${word}gtmpvc.output.spmreg/rh.mgx.ctxgm.fsaverage.pvc.VT.sm00.proj-0.5.nii.gz --cortex --trgsubject fsaverage

followed by smoothing, concatening and then a group comparison. However then I obtained the following error:

ERROR: cannot find /usr/local/freesurfer/stable6_0_0/average/mult-comp-cor/fsaverage/lh/cortex/fwhm37/pos/th13/mc-z.csd

Kind regards
