Hi i am trying to transform/morph a tract created with tracula into my cvs template subject space, using v.5.0 i am thinking the bb register transformation i am using is not the correct one, but it seems the logical choice, but obviously not working good as forceps minor ends up wraped around t

sandra, the two fsaverage's that you are using are the same. you can change one of the links to point at the other if you prefer, or continue to use it as-is. it will not affect the results. n. On Tue, 2012-01-10 at 15:10 -0500, swood...@nmr.mgh.harvard.edu wrote: > Hi all, > > We are trying

Hi all, We are trying to run exactly the same analysis, particularly the recon-all command, from two different directories. We've found that both directories have '/fsaverage' but that they are sourcing two different links/paths. Why is this and is there a difference in how analysis will be run/

Hi Zonglei, you should contact the FSL list as to exactly what there requirements are and how to get your data to that point. doug Zhen Zonglei wrote: > > I use FEAT from FSL to do the fMRI analysis. But the data were > unpacked with the Freesurfer unpacksdcmdir. > > > Zonglei Zhen > > > > On

Thanks to both Donald and Michael for catching my mistake about recommending sample-size weighting within the contrast (both responses are below). Depending upon the hypothesis being tested it is ok, but you're probably not going to be in a situation in which you will want to. doug --

malcolm, i attempted to add openmp support a few years ago but couldnt get it working across the build. in principle it would be great to get it working with freesurfer, but in practice threading issues and validity of results will consume an order of magnitude more time than that to get openmp t

malcolm, running 'make check' is one way to check the build. we run that nightly on our three build platforms (linux 32b, 64b and mac leopard). a goal of our linux centos build is to have it run on as many linux variants as possible without people having to modify their local install, and to tha

Hi all, I'm posting a follow-up to my thread from November regarding "anterior temporal lobe problems", so that it can be captured in the FS archives. Based on a suggestion from Bruce, we tried re-running (from scratch) using the -mprage flag in recon-all (since ours were MPRAGE acquisitions) as

Hi Bruce, Thank you for your quick reply. I installed v5.1.0 from the website and that name is what comes up when I open a terminal window. However, I tried typing recon-all -version and got $Id: recon-all,v 1.379.2.17 2011/05/20 22:48:18 nicks Exp $. So I'm not sure if that means the versio
