Re: [HCP-Users] Question about unprocessed fMRI data
Hi Ben, Yes, the CMRR multiband sequence incorporates "dynamic off-resonance in k-space” (DORK)” method as in Pfeuffer et al., MRM 2002, which has already been implemented in the Siemens product EPI sequence ICE recon.

[HCP-Users] Question about unprocessed fMRI data
Dear HCP experts, I am trying to better understand the unprocessed fMRI data. Does the online reconstruction include corrections for spatial shifts due to B0 fluctuations? There is a note about this in Ugurbil et al 2013 but I am wondering if this applies to the final HCP acquisition protocol. Thank you!
