Table 2.

List of meta-data provided by a FocusStack object (continued from Table 1).

Meta-data parameter name	Contents
FRAME-RELATED META-DATA
vtGlobalTime	The time in seconds since the first frame in the stack. (FSI)
vnBlockIndex	The index of the block (data file) the associated frame falls within. (FSI)
vnFrameInBlock	The index of the associated frame within the block, with the first frame given index 1. (FSI)
vtTimeInBlock	The time in seconds since the first frame in the block. (FSI)
vnStimulusSeqID	The stimulus sequence ID associated with each frame. (FSI)
vtTimeInStim Presentation	The time in seconds of the associated frame since the onset of the stimulus in which the frame falls. (FSI)
vnPresentationIndex	The index of the current stimulus presentation in the entire stack. The first stimulus is given index 1. (FSI)
vbUseFrame	A boolean value associated with each frame, indicating whether that frame should be used for analysis. (FSI)
tfBlankMean, tfBlankStd	Mean and standard deviation distribution of the baseline distribution assigned to a stack. Obtained by referencing a stack using fs.BlankFrames(<stack reference>) or by using the FocusStack/GetCorresponding BlankFrames class method
	The baseline distribution is assigned using the FocusStack/AssignBlankFrame class method (see Section 3.1.2 and Listing 1)

Parameters listed that specify “FSI” for access are obtained using the FocusStack/FrameStimulusInfo class method, and are computed from the parameters given in Table 1.
