That code snippet is what we use. There is an adjustment for the average surface because it has much less surface area than an individual. doug > Hi Lars, > > I think the formula is: > > fwhm = (2.3*sqrt(niter*2/pi)); > > Doug's in Florence, so may not reply right away. I think there's also a >

Yes, I did implement Moo's smoother. The problem was that it was impossible to comute the final fwhm based on the number of iterations, so it was not very useful. doug > thanks Don, > > one warning: Doug implemented Moo Chung's smoothing and we didn't find > quite the same results he reported. T

[Freesurfer] Resuming recon-all

Hi, some of my subjects crash due to memory-failure way into the recon-all stream. Is there any way I can resume the processing stream from where it crashed without having to write all the individual commands for the rest of the stream? For example, if my subject crashed during autorecon2 -cal

Martin, There isn't one command to do this, but sometimes it is easier to run things piece-wise using the -no flags. To rerun something starting at -calabel you could use: Recon-all -autorecon2 -nogcareg -nocanorm -nocareg -nocareginv -normneck -noskull-lta -s Jenni -Original Message-

[Freesurfer] resuming autorecon2

I'm running autorecon2 and i forgot to turn off the setting on my computer that automatically stalls any processes that are going at the time and asks for a log-in password when the computer sits idle for a while. I logged back in and it appears autorecon2 has stalled because of this. The comman

there are options to recon-all to run any set of individual steps, but this seems more trouble than it's worth. Just rerun it would be my advice. Bruce On Tue, 13 Jun 2006 [EMAIL PROTECTED] wrote: I'm running autorecon2 and i forgot to turn off the setting on my computer that automatically st

Thank you, Don. However, I try your code and matlab tells me 'Undefined function or variable 'fs_fread3''. Could you post other matlab function which are used by your 'fs_read_surf.m' and  ' fs_find_neighbors.m'? RonDon Hagler <[EMAIL PROTECTED]> wrote: >From: "R. Chen" >To: freesurfer@nmr.mgh.ha

Nam, Are you using Linux Fedora Core and an NVidia graphics card? If so, then I have seen a problem where just a snippet of a surface is displayed in tksurfer. The solution is to upgrade the nvidia driver. You will have to go to the nvidia web site to get that driver. Nick > Hi all, > > I've

that's the (not very informative) output of the nonlinear volume morph. It can take a day depending on your hardware, so expect it to go on for a while. I'll try to make the output a bit more interesting. On Tue, 13 Jun 2006 [EMAIL PROTECTED] wrote: my terminal screen has been sitting on th

This is normal. mri_ca_register can take 10 hours. To see if it is still running, open another terminal and type top, you should see all the running processes. Check http://surfer.nmr.mgh.harvard.edu/fswiki/recon_2dall to see approximate run times for each step. Mike [EMAIL PROTECTED] wrote:

Hi Ron, "fs_fread3" is actually just what I renamed the fread3.m found in $FREESURFER_HOME/matlab. I actually made no changes; just wanted my own self-contained set of matlab scripts. Anyway, here it is: % function [retval] = fs_fread3(fid) % [retval] = fd3(fid) %
