[Freesurfer] Resolution information

2014-02-24 Thread
Hi all, I got a few copies of freesurfer data from some data base. Is it possible to know the resolution of the MRI images, for example, the brainmask.mgz file, in freesurfer? Thanks,Yue___ Freesurfer mailing list

[Freesurfer] volume to surface

2013-12-19 Thread
Hi All, I would like to use "mri_vol2surf" to overlay a volume onto a surface. The synopsis is mri_vol2surf [] --src inputfile --out outpufile --srcreg registrationfile --hemi hemisphere.But I don't know how to generate the registrationfile. Could someone help me with that? Thanks a lot! Yue

Hi Bruce, Thanks for the information. The surface works for me. These histograms generated from the surfaces, if I understand correctly, are based on the intensities along the boundaries of one region. Can I also generate histograms including the whole region? Like Pick putamen or caudate and g

Hi All, I have T1-weighted MPRAGE images and I run recon-all to generate surfaces and labels in freesurfer. Then I would like to do statistical analysis in the regions I am interested in. For example, I would like to generate a histogram of intensities in frontal cortex or in occipital. I can di
