Re: [Freesurfer] Putting results from probabilistic tractography on the surface

Hi Sara no worries. The units are mm, and use -avg averages the values and max takes the max over them (which is a somewhat dicey thing to do if you are going to do stats afterwards). cheers Bruce On Wed, 11 Jul 2018, Sims, Sara A wrote: External Email - Use Caution Bruce, The help

Re: [Freesurfer] Putting results from probabilistic tractography on the surface

External Email - Use Caution Bruce, The help file and wiki don't explain the units of the min, max, and del. I still can't get the data to sample onto the surface correctly and so I'm wondering if it has something to do with my assumptions about how this command flag is working.

I think it is short for "delta" - how far about the samples are On Mon, 9 Jul 2018, Sims, Sara A wrote: External Email - Use Caution Bruce, What does "del" mean in the --projdist-avg flag? Sara Sims Graduate Research Fellow University of Alabama at Birmingham Department of Psychology

Hi Sara check out the help (with --help). For example you could use: --projdist-avg min max del : average along normal cheers Bruce On Tue, 26 Jun 2018, Sims, Sara A wrote: External Email - Use Caution Bruce, Thanks! So if I set it to say 4mm would it sample from 0-4mm or just fro

Re: [Freesurfer] Putting results from probabilistic tractography on the surface

External Email - Use Caution Bruce, Thanks! So if I set it to say 4mm would it sample from 0-4mm or just from exactly 4mm and ignore things slightly closer to the surface? My problem would be somethings could be 2mm or 3mm etc. and it's not exactly the same all the way around th

[Freesurfer] Putting results from probabilistic tractography on the surface

External Email - Use Caution Hello, I have outputs from FSL probtrackx that I would like to display on Freesurfer surfaces. If I put the volume into freesurfer space how can I get it to sample onto a surface when the values are in white matter and not grey matter? To rephrase, h
