-**fScan Reference Manual, Chapter 2 (CmdLineOptions:Expr): censor** 
-===== censor -- ===== 
- **usage:  -expr censor [timeref] [flag]**\\ 
- -expr censor [ref] [flag [fillindex] [fillimages]]  
- 
- 
-CENSOR replaces flagged time points with new values. By default, time points are flagged using the data set's "ACTIVE" reference timeline (0/1 value for each image).  Alternatively, time points can be flagged by explicitly specifying a reference time course (TIMEREF). 
- 
-All voxels in images with a 0 reference value will be replaced according the the FLAG argument, as:\\ 
-FLAG:\\ 
-  * 0 - replace with linear interpolation of surrounding time points (default) 
-  * 1 - replace with spline interpolation of surrounding time points 
-  * 2 - replace with zeros 
-  * 3 - excise the value (result is fewer time points) 
- 
-Other FLAG values can be combined with the above byb addition:\\ 
-  * 4 - adjust values after 0 reference values to have similar means to earlier values (matches means of 3 values before and after) 
-  * 8 - The TIMEREF is a list of time point indices to censor (default is TIMEREF is 0/1 flag for every timepoint) 
-  *   adjust values after censored values to have similar means to earlier values (matches means of 3 values before and after) 
- 
- /* val:  0 - (default) replace with linear interpolation; or 
-              same as VAL=8 if VAL2 is non-zero 
- 1 - replace with spline interpolation 
- 2 - replace with 0's 
- 3 - excise 
- 4 - match post-mean to pre-mean 
- 8 - replace with value at 1st censored timept at or after timept VAL2 
- 9 - replace with value at 1st uncensored timept at or after VAL2 
- 10 - replace with value at timept VAL2 
- 16 - active is t-index; otherwise is 0/1 flag
