External Email - Use Caution Dear freesurfer experts,
I want to create an equivolumetric surfaces (using the tool from: https://secure-web.cisco.com/1RxQBNBh7QLlgBP46WWIONAGLCrtuooPBalXpNMTOlsF1eoOQXja0KaogvHBx39bkqpnP1Qnz5FuZhT-DTLRXZLIQWp64WXTSgyrwspQMNHWCVzQPv1cqguMDF7AiGzYh01WxTW7m8FHiaJUhjGnV4OUOHBvBdP7TEBNSTE-wITBcBhQio6M-0BWoLcRMIE8ov3uosoZa-RneDMp9tALUDf97709r5pZLfXcySduo0v7WZYNjE9grdo_LK1JjVuAC/https%3A%2F%2Fgithub.com%2Fkwagstyl%2Fsurface_tools <https://secure-web.cisco.com/1RxQBNBh7QLlgBP46WWIONAGLCrtuooPBalXpNMTOlsF1eoOQXja0KaogvHBx39bkqpnP1Qnz5FuZhT-DTLRXZLIQWp64WXTSgyrwspQMNHWCVzQPv1cqguMDF7AiGzYh01WxTW7m8FHiaJUhjGnV4OUOHBvBdP7TEBNSTE-wITBcBhQio6M-0BWoLcRMIE8ov3uosoZa-RneDMp9tALUDf97709r5pZLfXcySduo0v7WZYNjE9grdo_LK1JjVuAC/https%3A%2F%2Fgithub.com%2Fkwagstyl%2Fsurface_tools>) and to sample the intensities of the T1wDividedByT2w volume at all the depths. I created the surfaces and after running the mri_vol2surf command I faced the error below. I don’t know why the path to the surface is not correct. I tried it in different devices with different versions of freesurfer but the results were the same. Any idea what I did wrong?
