External Email - Use Caution
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
