Some of the custom protocols available at the CIS are documented here.
Also known as simultaneous multislice. Acquires two or more slices simultaneously in each volume to dramatically reduce TR.
Acquires two or more acquisitions with different echo times in each volume. Helps differentiate BOLD and non-BOLD signal in T2* scans. Great introduction available here and one of the original papers here.
Processing multi-echo data is generally done with Multi-Echo Independent Components Analysis (ME-ICA). There is an AFNI program and a Bitbucket repository for performing ME-ICA.
