Re: [Freesurfer] Problem running recon-all with option -qcache

2011-02-07 Thread Ed Gronenschild
Hi Doug, Indeed, you are right, I forgot to run recon-all -autorecon3. It is not well documented that after running -autorecon2-wm one should also run -autorecon3. I had the impression that this portion was executed automatically by -autorecon2-wm. Ed On 2 Feb 2011, at 18:03, Douglas N Greve wr

Re: [Freesurfer] reg-feat2anat: a problem!

2011-02-07 Thread Douglas N Greve
Hi Aga, are you using nifti? If analyze, that could be the problem. Do your functionals and anatomicals have a different sign to their determinants (you can check with mri_info). In principle, reg-feat2anat should handle this but in some cases it does not. The 5.1 version will handle it properl

I get this behavior with --out_orientation, but not with --in_orientation. Are you sure it happens with both? And are you sure you want to be changing the orientation? If you have a volume from a person in the scanner head-first supine, then the answer is almost surely no. doug Reza Farivar w

Dear Doug, Thank you a lot! Our feat data is always nifti, but anatomical FSL data is sometimes in the analyze format. Is this already a problem? I will now check the rest. Thank you, cheers, Aga On 2/7/11 4:35 PM, "Douglas N Greve" wrote: > Hi Aga, are you using nifti? If analyze, that could

Hello, We are trying to set up the analysis for a periodic design alternating between 30s rest and 30s active condition. Because abblocked doesn't require a paradigm file, how do we specify which condition comes first (rest or active)? We understand that abblocked expects that the conditions wil

The contrasts are going to be created automatically. These will be: fund - stands for "fundamental" - this is the F-test of the sine and cosine components, probably what you want fund-sin -- t-test of the sine component (this may also be useful) fund-cos -- t-test of the cosine component (think of

Hi Doug, For some reason, our mkanalysis-sess command only created an analysis.info file and not a .cfg file, so we can't run the abblocked analysis using sfa-sess. Do you know what might cause this? We are using: freesurfer v5 our subjects directory: /cluster/manoach/milton/subjects command
