5.5.3.12. NewContVar Function

NewContVar Function

Creates a new continuous variable.

Syntax

variableReference NewContVar(doc, frequency, mVmin, mVmax)

Parameters

Parameter Type Description

doc documentReference Reference to the document.

frequency double Specifies the sampling frequency of the new

variable (in Hz).

mVmin double Minimum of the values of the new variable (in

milliVolts).

mVmax double Maximum of the values of the new variable (in

milliVolts).

Returns

Returns a reference to the new variable.

Comments

NeuroExplorer stores the values of continuous variables as scaled 2-byte integers. Specifying

minimum and maximum of the variable values helps to determine the correct scaling factor for the

new variable.

Usage

NexScript

doc = GetActiveDocument()

freq = 1000.

% create new variable in the file

doc.Temp1 = NewContVar(doc, 1000., -500.,500.)

% add the values to the new variable

for i = 1 to 10000

% timestamp

ts = i/freq

% value

value = 500.*sin(ts)

AddContValue(doc.Temp1, ts, value)

end
