Hi! I am processing a resting state data set, which I would like to low pass filter to get rid of some artifacts. The sample will be very small, so I won't run a RFX GLM, but an FFX GLM and/or single subject analyses. Since the low pass filter introduces high autocorrelations, it does not make sense to whiten the data before the GLM. However, in order not to violate the assumptions of the OLS, I would like to use the precoloring approach described in Worsley & Friston 1995. Is that by any chance implemented in FSFAST, and if not, where would be the right place to add it? Thanks in advance, Caspar
