REML
OLSQ
¥ Very little difference between OLSQ and REML, even at so low a threshold
¥ Data is markedly less correlated in time (UNM Siemens 1.5 T), as shown by maps of REML-estimated r1
¥ Similar data from U Iowa GE 1.5 T has similarly low temporal correlation
¥ BWH & MGH 3 T data has higher temporal correlation than FBIRN 1.5 T, but lower than NIH 3 T —— ???
