You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: export_channel_atlas.m
    path of file: ./repos/brainstorm3/toolbox/io
    
    the code of the file until where you have to start completion: function TsvFile = export_channel_atlas(ChannelFile, Modality, TsvFile, Radius, isProba, isInteractive)
% EXPORT_CHANNEL_ATLAS: Compute anatomical labels for SEEG/ECOG contacts from volume and surface parcellations
%
% USAGE:  TsvFile = export_channel_atlas(ChannelFile, Modality='ECOG+SEEG', TsvFile=[ask], Radius=[ask], isProba=[ask], isInteractive=1)
%         TsvFile = export_channel_atlas(ChannelFile, iChannels,            TsvFile=[ask], Radius=[ask], isProba=[ask], isInteractive=1)

% INPUT: 
%     - ChannelFile   : Path to Brainstorm channel file to be processed
%     - Modality      : String, export only the channel with the selected modality
%     - iChannels     : Array of integers, export only the selected channel indices
%     - TsvFile       : Output text file (tab-separated values)
%     - Radius        : Size in millimeters of the neighborhood to consider around each contact
%     - IsInteractive : If 1, display the output table at the end
