[Freesurfer] Video card/linux distro for 3D dual monitors: Recommendations?

2005-12-05 Thread Graham Wideman
Folks: Having developed high blood pressure due to the incredible time waste involved in trying to get anything other than lowest-common-denominator video running on linux... I thought I'd ask you all for recommendations that you know *do* work. So I'm looking for some combination of video c

Hmmm, when you say it looks "splotch" do you mean that it just looks pixelated? or that there are wholes in it? I would expect that the ribbon would fill in all the space between the two surfaces with some voxels jutting out beyond the surface. Your interpretation of delta is correct doug

Hi Doug, I tried lowering delta to really low values, eg., .001, but it doesn't seem change things much. Under ideal circumstances, would I expect the space between the white and pial surfaces to be completely filled? Also, I noted the -help states that delta is relative to the thickness at

>From --help on mri_label2vol: --proj type start stop delta Project the label along the surface normal. type can be abs or frac. abs means that the start, stop, and delta are measured in mm. frac means that start, stop, and delta are relative to the thickness at each vertex. The label defin

Jane, This is an unusual error, since tkmedit and tksurfer do not use the ITK library. To figure out how libitk3.2.so is being referenced, can you send me the output of this command: ldd `which tkmedit` I suspect there is some conflict between the FSL setup and Freesurfer, as FSL does use ITK

Hi Martin, the control points won't hurt the aseg unless you actually put them in the basal ganglia or thalamus. As long as they are clearly in wm you should be fine. Bruce On Mon, 5 Dec 2005, Martin Ystad wrote: Hi, I'm using a lot of control-points (typically 200-500) to compensate for

[Freesurfer] Control-points

2005-12-05 Thread Martin Ystad
Hi, I'm using a lot of control-points (typically 200-500) to compensate for intensity inhomogeneities in my images. This tends to create a rather uniformly looking white matter without any clearly discernible anatomical landmarks, such as the basal ganglia, etc. Does this mean that the subcortic
