Dear Jackie,

You may want to use the soft segmentations; you can obtain them by setting the environment variable WRITE_POSTERIORS to 1 before running the code, see:

https://surfer.nmr.mgh.harvard.edu/fswiki/BrainstemSubstructures

Also: you can obtain the voxel size with:

mri_info brainstemSsLabels.v10.mgz

Cheers,

/E

To whom it may concern

 

I used the freesufer brainstem segmentation, and I want to calculate the area of the segmented brainstem by slices. Would you like to let me know the pixel value of all three directions.  I used the result in brainstemSsLabels.v10.mgz. Many Thanks!

 

Best 

 

Jackie
