[Freesurfer] Labels to MNI152, SPM compatible

2016-08-02 Thread Matyáš Kuhn
Hi Freesurfer experts, I just started to use Freesurfer and I was wondering how can I convert images from MNI305 which uses Freesurfer to MNI152 which is used by SPM. We would like to get MNI152 template of Yeo parcelation (http://surfer.nmr.mgh.harvard.edu/fswiki/CorticalParcellation_Yeo2011)

From the names, it looks like both the seg vol and the template vol are both in mni152. Where did Yeo2011_17Networks_MNI152_FreeSurferConformed1mm_LiberalMask.nii.gz come from? One thing you can try is to invert the registration by adding --invertmtx to the command line. On 8/2/16 8:18 AM, M

The Yeo2011_17Networks_MNI152_FreeSurferConformed1mm_LiberalMask.nii.gz comes from http://surfer.nmr.mgh.harvard.edu/fswiki/CorticalParcellation_Yeo2011, and the description says it is the FSL MNI152 1mm template interpolated and intensity normalized into a 256 x 256 x 256 1mm-isotropic volume

[Freesurfer] DTI of frontostriatal tracts

2016-08-02 Thread Ritobrato Datta
Hello All, We are studying adolescents with HIV and are interested in frontostriatal tracts (anything from frontal cortex to caudate/putamen/nucleus accumbens) and tracts connected to the amygdala. Is anyone aware of DTI based atlases where these tracts are defined in MNI or some other standa

2016-08-02 Thread Douglas N Greve
I have been doing simulations similar to #1 (Eklund) using surface-based analysis on both thickness and fMRI. I'll prepare a report of the results, but the early indications are that the same effect is in play, though it does not look like the effects are as bad as in Eklund. For thickness ana

The voxel size and dimensions of all three volumes are the same: 256^3 and 1mm^3. Why do you think they are not? On 08/02/2016 09:17 AM, Isabelle Deschamps wrote: > Yes, of course. The upload is now active. > > Thank you again for your help, > > Isabelle > On 2 Aug 2016, at 08:55, freesurfer-req

Hello, I am trying to perform between-subject statistics on cortical DTI data in certain ROIs. I can do this by overlaying the DTI data on the surfaces on tksurfer, load and mask the label with the ROI, and then go to File -> Save Overlay. After doing this for all subjects I can perform statistic

By default they are in talairach. But you can get mni305 by adding --nofixmni to the surfcluster command line On 08/02/2016 03:36 PM, Sabin Khadka wrote: > Hi Doug, Thanks. Are these coordinates in talairach or MNI space? From > previous post you mentioned these are in mni305 space but if I look
