[Freesurfer] incongruent coordinates in freeview and *sig.cluster.summary

2014-04-26 Thread charujing123
Hi all, I have done group analysis and see it in freeview. Also I can see my sig.cluster.summary file to find clusters those survived. As I know, the MNIX MNIY MNIZ in the cluster summary file is coordinates for the maximum. The coordinate system is MNI305. Also I input the vertex number at the

[Freesurfer] converting volume-based mask into surface-based fsaverage

2014-04-26 Thread charujing123
Hi FS experts and users I created a rIPL mask by other tools and I want to make it surface-based mask. I ran this command: mri_vol2surf --hemi rh --reg register.dat --mov ./rIPL.nii.gz --o ./rIPL_afni.mgh --trgsubject fsaverage And it echo this output, that is to say, it cannot find the

Thanks, Doug! I looked at the examples on the wiki, and the Paired Analysis wiki page as well. You mentioned I should include the categorical and continuous variables in the fsgd file for the mri_glmfit. It seems that one of my analyses includes few subjects, and then one of the class end up

[Freesurfer] Question about visualization on the surface

2014-04-26 Thread Kaveh Kohan
Dear All, This probably a newbie question, so I apologize if it is a naive one, please bear with me. I have on value for each ROI on the surface of brain and one value for each sub-cortical structures. Those ROIs and sub-cortical structures correspond to freesurfer atlas. I have three

[Freesurfer] MNI -- freesurfer coordinate conversion

2014-04-26 Thread Kaveh Kohan
Hi Everyone, I was wondering if there is anyway to convert MNI coordinate to freesurfer coordinates? Let me explain a bit more: I have a set of points with their coordinates in the MNI atlas, I would like to find the closest ROI's (or better rank ROIs) with respect to their distance to those
