Internally, samseg uses partial volume to compute a more accurate
volume. They should still be very close though.

Hi freesurfer team
I use samseg for lesion segmentation. In the result of .stats i see
the lesions volume. But when i extract lesions seprately as a new file
we know that it uses the label 99 for extraction. But when i calculate
the volume of this extracted lesions which i created it seprately. The
volume of these two results are not the same.
The volume of extracted lesions seprately is higher than what samseg
automatically calculated in .stats file.
Why is this happened? Why the volumes are not the same. And how can i
calculate the lesions volume from extracted file that i created which
is a flair that i masked with label 99? How can i recalculate the
lesions volume from just exracted lesions filr without using samseg?
Thanks a lot for your help
