The Script DAT runs a script each time the DAT cooks and can build/modify the output table based in the optional input tables. The Script DAT is created with a docked (attached) DAT that contains three Python methods:
cook method is run each time the Script DAT cooks. The
setupParameters method is run whenever the Setup Parameter button on the Script page is pressed. The
onPulse method is run whenever a custom pulse parameter is pushed.
Refer to Help -> Python Examples, and Help -> Operator Snippets.
Note: Because the Script DAT can get data from anywhere, it's difficult to determine what it procedurally depends on. So every time that any Script OP runs it will add to a list of operators, parameters, nodes etc that it depends upon, and when they change, the Script OP will re-cook. The list is reset when a

Info CHOP Channels
Extra Information for the Script DAT can be accessed via an Info CHOP.
Common DAT Info Channels
- num_rows - Number of rows in this DAT.
- num_cols - Number of columns in this DAT.
Common Operator Info Channels
- total_cooks - Number of times the operator has cooked since the process started.
- cook_time - Duration of the last cook in milliseconds.
- cook_frame - Frame number when this operator was last cooked relative to the component timeline.
- cook_abs_frame - Frame number when this operator was last cooked relative to the absolute time.
- cook_start_time - Time in milliseconds at which the operator started cooking in the frame it was cooked.
- cook_end_time - Time in milliseconds at which the operator finished cooking in the frame it was cooked.
- cooked_this_frame - 1 if operator was cooked this frame.
- warnings - Number of warnings in this operator if any.
