WindowBackgroundColor

The window's background color, given as an RGB value. For convenience, RGB values may be entered in hexadecimal notation, e.g. 0xff0000 for red.

PreRunDuration

The duration of the pause preceding the first sequence. Given in sample blocks, or in time units when immediately followed with 's', 'ms', or similar.

PostRunDuration

Duration of the pause following last sequence. For the StimulusPresentationTask, classification announcement ("The result was...") and classification result will be played back during this period. Given in sample blocks, or in time units when immediately followed with 's', 'ms', or similar.

PreSequenceDuration

Duration of the pause preceding sequences (or sets of intensifications). Given in sample blocks, or in time units when immediately followed with 's', 'ms', or similar.

PostSequenceDuration

Duration of the pause following sequences (or sets of intensifications). Given in sample blocks, or in time units when immediately followed with 's', 'ms', or similar.

StimulusDuration

For visual stimuli, the duration of stimulus presentation. For auditory stimuli, the maximum duration, i.e. playback of audio extending above the specified duration will be muted. Given in sample blocks, or in time units when immediately followed with 's', 'ms', or similar.

ISIMinDuration, ISIMaxDuration

Minimum and maximum duration of the inter-stimulus interval. During the inter-stimulus interval, the screen is blank, and audio is muted.

Actual inter-stimulus intervals vary randomly between minimum and maximum value, with uniform probability for all intermediate values. Given in sample blocks, or in time units when immediately followed with 's', 'ms', or similar. Note that temporal resolution is limited to a single data block.

InterpretMode

An enumerated value selecting on-line classification of evoked responses:

  • 0: no target is announced "attended", and no classification is performed;
  • 1: online or free mode: Classification is performed, but no target is announced;
  • 2: copy mode: pre-defined targets are announced, classification is performed.

DisplayResults

Switches result display of copy/free spelling on or off.
