RE: [Freesurfer] remote batch job?

2007-08-16 Thread Don Hagler
There is a renderoffscreen flag that can be used from a tcl script. Unfortunately, this feature was broken when a particular section of the tksurfer code was commented out. The problem was that the tclscriptflag used to determine whether to open a window was not getting set to true. Look for

Hi Avram, the colin brain is around several places, but in general it's usually pretty misleading to present average data on an individual anatomy. It gives you the illusion of precision in localization that isn't present. That said, it's done all the time. Bruce On Thu, 16 Aug 2007, Avram

[Freesurfer] better looking structural for function display

2007-08-16 Thread Avram Holmes
All, I have a quick question. I would like to present some volume data on a detailed Talairach structural (the fsaverage talairach template is quite blurry). In SPM I can use the high resolution Collins brain. Does anyone know if that structural is available somewhere in the FreeSurfer system?

Dear FreeSurfers, I have completed individual and group level functional analyses using FS-FAST, and would like to correlate individual differences in self-report measures against the betas for several of my 13 conditions (I used -gammafit in mkanalysis). My questions are: 1) Where are the beta

[Freesurfer] procedural question about FDR correction

2007-08-16 Thread Dara Manoach
Hi, FDR correction for multiple comparisons gives you different p-values for the left and right hemispheres. It seems really weird to report in a paper: a) that you've corrected for the right and left hemispheres separately and b) that the p-value that gave rise to a corrected probability o

can you give us the details of the protocols? And are you talking about 2 different acquisitions on the same subject, or two groups of subjects with different acquisitions? If the latter then your groups must be balanced in terms of # of subjects for each acquisition type. On Thu, 16 Aug 2007
