External Email - Use Caution Hello FreeSurfer developers,
I'm having trouble running the command mri_surf2surf, and I haven't been able to find a fix in the message archives (a similar question has been asked, but I couldn't find the answer). I am trying to convert the pial and white matter surfaces for a series of subjects back to the anatomical space. I have computed the registration matrix to transform the surfaces, but am having trouble with the mri_surf2surf syntax. This is the command I am trying to run: mri_surf2surf --hemi lh --sval-xyz pial --reg register.native.dat rawavg.mgz --tval lh.pial.native --tval-xyz --s <subjectID> and I get an error saying that --tval-xyz requires an input volume. (The syntax described on the website (https://surfer.nmr.mgh.harvard.edu/fswiki/FsAnat-to-NativeAnat) is out of date.) I have tried to use rawavg.mgz as the input volume, but then I get an output that can only be read as a scalar overlay, and I need an actual surface. When I try to use a surface as the input, I get an error saying that the file type cannot identified. Do you have any suggestions for what I am doing wrong? Thank you, Kathleen Larson Department of Biomedical Engineering Vanderbilt University 304 Featheringill-Jacobs Hall (425)-894-2005
