External Email - Use Caution Hello Freesurfer experts,
I am attempting to register a ROI (.nii) to the surface of fsaverage to get the statistical output on the cortical thickness. I followed your instructions on https://secure-web.cisco.com/1vMR3HBqveQVdV1izVoGaJ5VcRtbR7HBn6ADoe1ai7ok5utz9wmCB_PLEjDtsOmyziziVBQRSmBgczrdyk56eX0vaBWBNP1iIevBdxOho3o-JJ64DuVK1J6XpzIFNVqqzBDHDrU6O2cYjWTNnglb4Ow4OIdXr5Qq28eboicyUSvLl2KmB0P0lQY9abQIfjX6hs_1Q1FvwX1Tx7YnGwsbJIgqcpDRG0dkvqZc0pgeiBQbnNjLadwozbHME2Ale8Kt0-V-I2Urmgq5zbEhzlAPvCA/https%3A%2F%2Fsurfer.nmr.mgh.harvard.edu%2Ffswiki%2FVolumeRoiCorticalThickness <https://secure-web.cisco.com/1vMR3HBqveQVdV1izVoGaJ5VcRtbR7HBn6ADoe1ai7ok5utz9wmCB_PLEjDtsOmyziziVBQRSmBgczrdyk56eX0vaBWBNP1iIevBdxOho3o-JJ64DuVK1J6XpzIFNVqqzBDHDrU6O2cYjWTNnglb4Ow4OIdXr5Qq28eboicyUSvLl2KmB0P0lQY9abQIfjX6hs_1Q1FvwX1Tx7YnGwsbJIgqcpDRG0dkvqZc0pgeiBQbnNjLadwozbHME2Ale8Kt0-V-I2Urmgq5zbEhzlAPvCA/https%3A%2F%2Fsurfer.nmr.mgh.harvard.edu%2Ffswiki%2FVolumeRoiCorticalThickness> but after mri_vol2surf I get this message, I can’t visualize the ROI on the surface. I I’m using Freesurfer 7.0.1. How can I solve this?
