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: ica_fuse_setup_analysis.m
    path of file: ./repos/fit/FITv2.0e/ica_fuse
    
    the code of the file until where you have to start completion: function fusionFile = ica_fuse_setup_analysis(inputFile, fusionFile)
% function for setting up parameters required for data fusion analysis
% parameters required are:
% 1. output directory
% 2. prefix for output files
% 3. data - of structure format
% 4. mask - mask for fmri data
% 5. Estimating
    
function maskFiles = getMaskFiles(featureNames, modalities, dataInfo)
% Get mask for each feature if possible

[maskFiles] = ica_fuse_selectMask(featureNames, modalities, dataInfo);


function typePCACallback(hObject, event_data, handles)
% Type of PCA callback

getStr = get(hObject, 'string');
getVal = get(hObject, 'value');

handles_data = get(handles, 'userdata');
inputFile = handles_data.inputFile;
if ~isfield(handles_data.fusionInfo.setup_analysis, 'dataInfo')
    error('Please select the data before selecting PCA type');
end
