 **fScan Reference Manual, Chapter 2 (CmdLineOptions:Expr): tsmooth**
 ===== tsmooth -- Temporal smoothing filter =====
- **usage:  -expr tsmooth npts [flag]**\\
+ **usage:  -expr tsmooth twin [flag]**\\
 TSMOOTH uses sliding window averaging across time to smooth each voxel time series.
-NPTS is how many contiguous time points to average together in the sliding window.
+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:\\
+FLAG (combine options by addition):\\
-  * 1 - subtract mean of each time course after smoothing
+  * 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
