fScan Reference Manual, Chapter 2 (CmdLineOptions:Expr): tsmooth

tsmooth -- Temporal smoothing filter

usage: -expr tsmooth twin [flag]

TSMOOTH uses sliding window averaging across time to smooth each voxel time series.

TWIN indicates how many contiguous time points to average together in the sliding window.
By default TWIN is the number of time points, but if FLAG&1 (odd value) then TWIN is in seconds.

FLAG (combine options by addition):

  • 1 - TWIN is the smoothing window in seconds (default is number of time points)
  • 2 - subtract mean of original time course from smoothed time course
  • 4 - subtract smoothed time course from original time course
