A robust method for correcting partial volume effect in ASL data
(1) Reading and writing images in nifti format;
(2) Implementing Modified least trimmed squares method (mLTS)
(3) Applying mLTS to ASL data for correcting partial volume effect
(3) Computing CBF maps for both GM and WM.
The method is described in the following paper:
