- | ===== censor -- replace or remove selected images from time series ===== | ||
- | | ||
- | |||
- | CENSOR replaces flagged with new values, or it can completely remove images. Which images to censor is controlled by a reference time series. By default, the reference time series is the data set's " | ||
- | |||
- | Usually the reference series should have at least as many values as their are images, in which case the images to be censored are those for which the corresponding reference value is less than or equal to zero (any positive reference value means keep that image). | ||
- | |||
- | Alternatively, | ||
- | |||
- | What happens to censored images depends on the values of the FLAG and FILLOPTION arguments. | ||
- | |||
- | FLAG - censoring operation: | ||
- | * 0 - (default) | ||
- | ** if FILLIMAGES | ||
- | * 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) | ||
- | * | ||
- | |||
- | /* val: 0 - (default) replace with linear interpolation; | ||
- | 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 | ||
