Dear FreeSurfer experts, I'm attempting to make cortical surfaces for a macaque brain, and am having trouble getting mri_fill to work. The command has worked without any errors for a different macaque dataset in the past, and I can't seem to figure out why it isn't working this time.
I am using v. 5.3 for Mac Snow Leopard, and I used the command (I have confirmed on tkmedit that the CC and pons seed coordinates are correct): *mri_fill -CV 125 119 147 -PV 125 103 65 wm.mgz fill.mgz* The log from running the command is as follows: -------------------------------------------------------------------------------------------------------- using voxel position (125, 119, 147) as corpus callosum seed point using voxel position (125, 103, 65) as pons seed point reading input volume...done. searching for cutting planes...INFO: volume does not have linear_transform set nor lta is given by option.-xform.
