The Error DAT lists the most recent TouchDesigner errors in its FIFO (first in/first out) table.
You can filter our messages using pattern matching on some of the columns like Severity, Type and path of the node containing the error. One column contains the absolute frame (
absTime.frame) in which the error occurred.
Parameters - Error Page
active - Inhibits and allows message to be added to log.
severity - Filter pattern for the output.
type - Filter pattern for the output.
source - Filter pattern for the output.
message - Filter pattern for the output.

Any of the procedural data operators. OPs do all the work in TouchDesigner. They "cook" and output data to other OPs, which ultimately result in new images, data and audio being generated. See .
