Hi Serena It means you don't have write permissions in the directory. You should invoke pico like sudo pico /Applications/freesurfer/.license ..it'll ask for your password and save successfully, provided you have permissions. -Krish On Aug 1, 2010, at 8:32 AM, sere f wrote: Hi All,

Re: [Freesurfer] Error when doing Talairach transformation

Hi Feng, have you looked at the talairach transform (talairach.xfm) to see if it is indeed incorrect? If so, you should correct it manually using tkregister2 (there is a tutorial for this on our wiki) cheers Bruce On Mon, 2 Aug 2010, Xue, Feng wrote: Dear Freesurfer experts, I'm

Re: [Freesurfer] Non-linear correlations

2010-08-02 Thread Douglas N Greve
There is nothing to fit nonlinear parameters. You can do some simpling things. Eg, if you believe that thickness is changing exponentially with time, th = exp(-a/t), then you can take the log of the thickness so that log(th) = -a/t, then fit for a. doug mmoayedi wrote: Hi Everyone, I was

This is with FSFAST? You can run isxconcat-sess on both analyses. For version4.X, this will create output files like lh.ces.mgh. If you keep the subject order the same for both analyses, then you can use mris_calc to take the difference between them (ie, a paired analysis). You will then have

The freesurfer results are going to be in the anatomical space (256^3, 1mm^3). Your functional results will be in a different space (eg, 64x64x30 or whatever), so you'll need to put the functionals into the anatomical space or the other way around. You'll need a registration matrix between the

If you're going to continue to use stable3 then you will need to have an old version of FSL (the ip program is an FSL program from several versions ago). Can you start using the new version of FSFAST? doug swood...@nmr.mgh.harvard.edu wrote: Additional info: FREESURFER_HOME:
