Hello, I would really like to use a freesurfer surface to display non-human primate data that I have already put into a standard space and segmented, but I am having trouble finding information on how to skip many of the initial steps to this point. Also, I have seen references to a "-monkey" opt

Keith, You will need to install the Compatibility standard C++ libraries for Fedora Core 4. You can get the rpm's here: http://rpmfind.net/linux/rpm2html/search.php?query=libstdc%2B%2B.so.5 look for Fedora Core 4. Nick On Fri, 2007-08-03 at 16:06 -0400, Keith Sudheimer wrote: > I am runnin

Thanks! This sounds very promising and we will try that time using the code you sent. As for the current mc data from mri_glmfit, does anyone know if Freesurfer can give cluster sizes as a function of corrected p-value like AFNI does? Thanks, Rob Don Hagler wrote: There is no reason why yo

hmmm, not sure i understand. You can visualize any scalar field in the volume, so yes. As for the volume, I guess you could create a functional volume with the value in each voxel the slice # that it is in and just paint that onto the surface as normal. cheers, Bruce On Fri, 3 Aug 2007, Paul

[Freesurfer] questions

Hello All, I have 2 questions I hope someone can help me with. 1) Is it possible to plot on a surface a set of arbitrary points in the coordinate frame of an anatomical volume? In other words if I have a set of x,y, and z points (not voxel indices: e.g. sub-voxel coordinates) can I plot the

RE: [Freesurfer] determining sizes of clusters at given CWP cutoff

2007-08-03 Thread Don Hagler
There is no reason why you shouldn't be able to get the cut-off size from monte carlo simulations. It just depends on the program you use to do it. For example, AFNI's AlphaSim gives cluster sizes as a function of corrected p-value. By the way, monte carlo simulations are a waste of time.

[Freesurfer] determining sizes of clusters at given CWP cutoff

Hi, I was trying to figure out if there is any way to determine the exact size at which clusters becomes significant given a specified significance, and it appeared from the mc-corrected overlay that in this overlay the clusters do not continously change in size but appear discretely at a giv

[Freesurfer] possible bug found in mri_surfcluster

2007-08-03 Thread Robert Levy
Hello, I found a possible bug in mri_surfcluster, but it may be linked specifically to average7 and no other srcsubjects (but I haven't checked that). When I run mri_surfcluster with cluster simulation data, the size is reported at a seemingly arbitrary number, based on the fact that the #of

Hello, We're designing a task that has two pairs of events (4 events total). Each pair of events has a pair of allowable null intervals associated with it. Is it possible to use optseq2 to create such a paradigm? Is it appropriate to use optseq2 in this case at all given these constraints? ___
