 **fScan Reference Manual, Chapter 2 (CmdLineOptions:Expr): tsmooth**
-===== tsmooth -- =====
+===== tsmooth -- Temporal smoothing filter =====
- **usage:  -expr tsmooth **\\
+ **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
