One way to do it is with mri_binarize: mri_binarize --i aseg.mgz --min 1.5 --max 2.5 --o wm-lh.mask.nii This will find all the voxels whose value is between 1.5 and 2.5 and set them to 1 in the output. In this case, it will make a binary mask of the left cerebral white matter as that has a cod

It depends on how you get your images in the first place. If you use mri_convert to convert from dicom files, then it uses information in the dicom header. I'm attaching the rules that mri_convert uses. If you get your data from somewhere else, then mri_convert will try to find the orientatio

Can you send the recon-all.log file? I can examine it for error messages. Also, do the input files contain orientation info? run this on your subject input volume: mri_info 001.mgz and send me the output. On Mon, 2006-07-17 at 13:58 -0700, Jake Freimer wrote: > I have run several instances

Hi Joe, You may want to try realvnc (www.realvnc.com). We have been trying their enterprise edition and it works really well. The typical vnc server that's installed does not support OpenGL. I do know that more recent editions of realvnc do support the GLX extension. Cheers, Satra -Origina

Joe, Does tkmedit work directly on the RH3 box? If so, then it is the windows box that does not have the GLX extensions built into its OpenGL driver. GLX allows running X windows apps (like tkmedit) to run using the OpenGL calls locally on a machine (for performance). I don't have experience ru

Hi Isabel, if dura is left around you are *much* better off than if brain is stripped. In the latter case we will never recover, while if there is some dura we generally can avoid including it in the surfaces. Note that in the screenshots you attached that the dura was labeled as cortex by the
