Dear HCP experts, I have two questions:
1) I understand that the reconstruction algorithm for fMRI changed with the Q3 data release. I believe there are three main GRAPPA reconstruction approaches for multiband imaging: SENSE/GRAPPA from Blaimer et al (2006); Slice-GRAPPA from Setsompop et al (2012); and Split-Slice-GRAPPA from Cauley et al (2014). Do the HCP reconstruction algorithms correspond to these methods? From my reading of Ugurbil et al 2013, p. 89, I thought the change was from SENSE/GRAPPA to Slice-GRAPPA, but I now see that the overview document http://www.cmrr.umn.edu/multiband/Multi-Band_C2P_Instructions_R013a.pdf includes a citation to Cauley. 2) I ultimately want to simulate data generated by coil sensitivities similar to the HCP scanners and head coils. Are single-band calibration data for each coil available?
