Hi FSL experts,
Following T1 segmentation in FSL using the tool FAST I got files for the segmented white matter, gray matter and ventricles.
In addition I generated map for the bias field.
In order to calculate white matter volume I used the following command line:
fslstats structural_bet_pve_2 -M -V | awk '{ print $1 * $3 }'
What is the exact usage of the bias field map. Do I need to correct the white matter volume using the bias field map?
Thanks
Jon
