Re: [Freesurfer] Discrepancy in volume calculated for thalamic nuclei in FreeSurfer

Hi Corinna, this is probably due to partial volume correction. The thalamic seg does not just count up voxels. The underlying model is a tetrehdra mesh, and that is used to compute partial volume. doug On 6/29/2020 6:06 PM, Corinna Bauer wrote: External Email - Use Caution Hello al

Not sure. One thing that is suspicious is that they all died within minutes of each other. That, and because there is no actual error message, makes me think that something went wrong on the computer around 7:20AM on June 22. How many CPUs do you have on caladan? It only has 250G of memory, so

External Email - Use Caution Hi everyone! Quick question. For my specific analysis, I’m most interested in the values given in the aseg.stats file. I’m comparing gray matter volumes from specific ROIs between patients and healthy controls. Thus, the outcome measures I will be r

External Email - Use Caution Dear Doug, Thanks for your quick response. I am now able to get roifile (i.e., Volume_Subcortical) from asegstats2table, which shows cortical volume values of all the subcortical regions. Next when I run: mri_glmfit --table Volume_Subcortical --fsgd
