One more question. Is it necessary to also do residual bias field correction for resting-state data? Thank you.

Are there any subjects from HCP 900 Subjects release scanned using other whole body scanners instead of this 3T Skyra system, which may not need this mandatory residual bias field correction? Thank you. ________________________________ From: Harms, Michael <[email protected]<mailto:[email protected]>> Sent: Sunday, August 28, 2016 1:52 PM To: Aaron C; [email protected]<mailto:[email protected]> Subject: Re: [HCP-Users] HCP script used for residual bias field correction on myelin maps Hi, It's in the PostFreeSurfer/scripts/CreateMyelinMaps.sh script.

It's described in Fig 18 of Dr. Glasser's 2013 paper "The minimal preprocessing pipelines for the Human Connectome Project", but I cannot find the actual script from HCP pipeline scripts.
