Hi

I want to do partial volume effect (PVE) correction for arterial spin labelling (ASL) data, because ASL data is low resolution: 3.5x3.5x4mm voxel. I need to correct PVE by using 3DT1 (1x1x1mm).
Now, I have spatially normalized 3DT1 and ASL data in MNI space.

There are several reproted ways to do partial volume effect correction.
At least, we need to have GM, WM and CSF probality map from 3DT1 data.

For example. the following paper reported the way to correct PVE.

Magn Reson Med. 2013 Feb;69(2):531-7. doi: 10.1002/mrm.24279. Epub 2012 Apr 23.
Improved partial volume correction for single inversion time arterial spin labeling data.
Liang X1, Connelly A, Calamante F.

Is there any way to correct PVE by using AFNI?

Thank you.
