Hello All,
I am trying to recalculate the 'brain percentage' value calculated by sienax as reported in the
*.sienax file using the volumes created by sienax.
for example, i have these values in my *.sienax file:
Class: CSF tissue 1 tissue 2 brain percentage
Volumes: 316748.7 516990.9 384503.5 0.739996
i was hoping to get the same volumes using avwstats++ on the PVE volumes but do not:
% avwstats++ 20071129_13_1_stdmaskbrain_pve_0 -l 0.50 -V
370841 297463.903287
% avwstats++ 20071129_13_1_stdmaskbrain_pve_1 -l 0.50 -V
665191 533571.830762
% avwstats++ 20071129_13_1_stdmaskbrain_pve_2 -l 0.50 -V
482694 387184.915728
i tried using the 'seg' volume but do not:
% avwstats++ 20071129_13_1_stdmaskbrain_seg -l 0.99 -u 1.01 -V
428073 343371.594489
% avwstats++ 20071129_13_1_stdmaskbrain_seg -l 1.99 -u 2.01 -V
641821 514825.976286
% avwstats++ 20071129_13_1_stdmaskbrain_seg -l 2.99 -u 3.01 -V
448832 360023.079002
How might I go about recalculating the 'brain percentage' value reported by sienax?
Happy New Year,
