Dear experts,

I am following  PetSurfer steps (https://surfer.nmr.mgh.harvard.edu/fswiki/PetSurfer).

Something was wrong using mri_coreg function  because when  I checked the registration with tkregisterfv this error was shown in the terminal:

Warning: Transformation can only apply to volumes for now. If your data includes ROI/Surface/Way Points, please do not use this feature yet.

MatrixAsciiReadFrom: could not scanf parms

Source temporarily unavailable

LTAchangeType: src geometry must be valid

Can you help me? 

*I use these commands:*

dcm2niix s_001_PET_dicom (to convert dicom PET files to nii)
gtmseg --s s_001
mri_coreg --s s_001 --mov s_001_PET.nii --reg s_001.reg.lta
tkregisterfv --mov s_001_PET.nii --reg s_001.reg.lta –surfs

And it happens with all the subjects.

Thank you in advance.
Best regards,
Marina.
