4. Bistim Subclass

The bistim.m class which is a subclass of magstim.m, is used to control BiStim^2 Magstim stimulators. This subclass inherits all the methods from its parent class, magstim.m, while also overwriting a few (i.e, getParameters) as well as adding some more commands for dealing with a Bistim device.

Inherited methods include Initialising, Connecting, Disconnecting, Enabling/Disabling Remote Control, Enabling and Disabling the device, Sending Single Trigger, Setting Amplitude of coil A power, and Getting Coil Temperature.

Setting Amplitude for Coil B:

This function allows you to set the power of coil B in the Bistim stimulator to the desired value.

magstimObject.setAmplitudeB(power);

• power {int}: is the desired power amplitude for stimulator B.

Setting Inter Pulse Interval:

By calling this function, you will be empowered to set the IPI value to the desired value.

magstimObject.setPulseInterval(ipi,checkWarning);

• ipi {double}: is the desired interpulse interval which is the interval between each paired pulse.
• checkWarning {bool}: is a boolean determining whether to check for potential warnings in the ipi boundaries.

Enabling/Disabling High-Resolution Mode:

To enable or disable the high-resolution mode on your device, you can call this function.

magstimObject.highResolutionMode(enable);

• enable {boolean}: is a boolean that can be True(1) to enable and False(0) to disable the High-Resolution time setting mode.

This subcalss will hold this information as a private property to later use it when trying to determine different parameters' boundaries according to the time setting mode of the Bistim device.

Getting Bistim Parameters:

This function overwrites the same method in its parent class and provides you with all the available information about the current instrument status and its various parameters.
