We don't have tools to do this. I guess you could use BV to do the correction and feed the output into recon-all. For 7T, we often run SPM VBM or segmentation to get a bias corrected output, then feed that into recon-all

Dear all,

1. BV have a tool:

https://www.brainvoyager.com/bv/doc/UsersGuide/HighResDataAnalysis/UsingPDScansForInhomogeneityCorrection.html

Is freesurfer have something similar for MPRAGE (i use recon-all)

2.Is PD is suitable also to correct MP2RAGE on 7T?

My resolution 1mm, I use recon-all.v6.hires (freesurfer/6.0.0-patch/hcp/)

Still, the segmentation in the inferior temporal and frontal pole are very bad...

Is it make sense to use PD in MP2RAGE sequence?
