classdef KTUEAMapFile

% UEAMAPFILE -- Defines a class that contains information on a UEA
% electrode array using CMP files provided by Blackrock Microsystems.
%
% To load a CMP file type 'MapName = UEAMapFile' where MapName is the name
% of the variable that will be created and will contain the map class.
%
% Example: myArrayMap = UEAMapFile;
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% METHODS:
%
% There are several available methods for mapfiles. Here's a list and a
% description of what they perform.
%
% Electrode2Channel(Electrode): 
%   Will return the Channel number corresponding to a passed Electrode.
%
% Channel2Electrode(Channel):   
%   Will return the Electrode number corresponding to a passed Channel.
%
% GetChannelBankID(Channel):
%   Returns the BankID for a passed Channel.
%
% GetChannelPin(Channel):
%   Returns the Pin for a passed Channel.
%
% GetChannelLabel(Channel):
%   Returns the Label for a passed Channel.
%
% GenerateChannelSubplot(Channel):
%   Returns a subplot handle for the passed Channel to be used in plotting
%   UEA-like maps.
%
% GenerateChannelSubplotNames(Channel):
%   Plots the names of channels and electrodes on the subplot corresponding
%   to the passed Channel.
%
% GetChannelColumnRow(Channel):
%   Returns the Column and Row positions of the passed number that is used
%   to plot UEA-like maps.
%
% PlotCMP:
%   Will plot a map of the CMP Map with all the electrode and channel
%   names.
