Trim windowing
A windowing policy of type trim trims the temporal interval of a trial, both from the start and from the end of a specified temporal amount (e.g., 3 seconds).
The trim windowing has the following structure:
type
string
{trim}
TRUE
the type of windowing strategy
trim
array of strings
The length of the array should be two.
Valid values should have the form of a whole number followed by either "s", "m", or "h"
TRUE
How to trim the temporal interval of a trial to get the window. ["0s", "10m"] means trim 0 seconds from the start of the interval, 10 minutes from the end. ["0s", "1h"] means trim 0 seconds from the start, 1 hour from the end
task
string
The name of a task of the workflow associated with the study
FALSE
If the field is specified, the trim offset calculation for the window will be applied from the start time of the assigned task. Otherwise, it will be calculated from the start time of the trial.
In case a windowing policy is not specified, the default windowing corresponding to trim[0s,0s] is considered.
Example
The following fragment shows a windowing strategy of type "trim" where the time window is specified to start 10s after the beginning of the trial and to end immediately before the end of the trial:
