6.3.6. FragmentTimestamps Method

Variable.FragmentTimestamps Method

For continuous variable, returns the fragment timestamp values in seconds. This method is valid only

for continuous variables.

In general, a continuous variable may contain several fragments of data. Each fragment may be of a

different length. NeuroExplorer does not store the timestamps for all the A/D values since they would

use too much space. Instead, for each fragment, it stores the timestamp of the first A/D value in the

fragment and the index of the first data point in the fragment. The timestamps of the first A/D value in

each fragment are returned by this method.

Syntax

SAFEARRAY(double) FragmentTimestamps()

Parameters

None.

Usage

Matlab

nex = actxserver('NeuroExplorer.Application');

doc = nex.OpenDocument('C:\Data\TestDataFile.nex');

% get the first continuous variable

cont1= doc.Continuous(1);

% get all the fragment timestamps

cont1FragmentTs = cont1.FragmentTimestamps();
