Just a note that there is resting-state data in a subset of subjects acquired at 7T, but the structural scans were not reacquired at 7T (since you were asking specifically about the myelin maps initially).
cheers,

I saw that Dr. Glasser et al.'s paper mentioned that the residual bias field of HCP Skyra data was caused by "the positioning of the head is ~ 5cm above isocenter and because of the smaller (customized 56 cm) body transmit coil making it more difficult to
achieve the kind of B1 transmit homogeneity found in other whole body scanners". 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]>

It’s in the PostFreeSurfer/scripts/CreateMyelinMaps.sh script.
Look for the stuff related to “MyelinMap_BC”.
cheers,

Could I find the shell or MATLAB script used for performing residual bias field correction on myelin maps somewhere online? 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. Thank you. _______________________________________________
