Hello,
My freesurfer version is freesurfer-Linux-centos4_x86_64-stable-pub-v4.3.0
I noticed that the aparc+aseg.mgz label map is resampled to 1mm x 1mm
x 1mm voxels,
eventhough the .mgz grayscale mri image file remains as per the
original voxel size and is not 1x1x1. mri_convert .nii to .mgz
translates the grayscale image down the y direction in the horizontal
plane transverse/axial slices.
I noticed that the aseg.stats files list the number of voxels and the
volume, and these numbers match because the voxel size is 1 x 1 x 1.
My question is whether freesurfer 4.3 can be invoked to perform
partial volume error corrections, and if so how do you invoke this
feature?
My interests lie in segmentations of the lateral ventricles including
their posterior and inferior horns.
thank you,
john
