Re: [Freesurfer] PET/MRI registration failed with bbregister or mri_coreg

you need to go back to the source data. At some point someone set or changed the voxel size to the wrong thing. This can sometimes happen in PET as reconstruction into volumes is not all that standardizeed On 10/12/2016 06:12 PM, Matthieu Vanhoutte wrote: > > Thank you for your diagnosis

Thank you for your diagnosis Douglas. How could I get the voxel sizes right from input nifti pet and mri data ? Best regards, Matthieu Le 12 oct. 2016 10:05 PM, "Douglas N Greve" a écrit : > The problem appears to be that the PET or the MRI (or both) have > incorrect

Re: [Freesurfer] PET/MRI registration failed with bbregister or mri_coreg

The problem appears to be that the PET or the MRI (or both) have incorrect voxel sizes (about 15%). You need to fix the problem. You can get a decent registration using something like mri_coreg --mov BS7_PET.lps.nii.gz --s 207118_FS_Filedrop --reg dof9.wb.lta --dof 9 --no-ref-mask --ref

Can you tar up the FS anat analysis and BS7_PET.lps.nii.gz and send it to me on our filedrop? On 10/3/16 6:55 AM, Matthieu Vanhoutte wrote: Hi Douglas, Please find below the mri_coreg terminal output : / / /$Id: mri_coreg.c,v 1.27 2016/04/30 15:11:49 greve Exp $/ /cwd
