usage: -expr censor [timeref] [flag]

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)
