Trial¶

Description¶

A container paradigm component.

The execution order and number of repetitions of a trial’s sub-components are determined by selection, nsamples, and sampling_method.

Signature¶

trial

Optional Parameters¶

interruptible¶

Default:: YES

If NO, then any request to pause or stop the experiment while this component is executing will be deferred until said execution completes. This behavior is inherited by the component’s children, making them non-interruptible as well.

selection¶

Options:: sequential

sequential_ascending

sequential_descending

random_without_replacement

random_with_replacement
Default:: sequential

Order in which to draw selections

nsamples¶

Default:: 1

Number of samples to allow before Reset Selections is required

sampling_method¶

Options:: cycles

samples
Default:: cycles

Controls the interpretation of nsamples. If set to cycles, all possible selections must be made to complete one sample. If set to samples, each individual selection counts as a sample.
