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: bfImport.m
    path of file: ./repos/u-shape3D/software
    
    the code of the file until where you have to start completion: function MD = bfImport(dataPath,varargin)
% BFIMPORT imports movie files into MovieData objects using Bioformats
%
% MD = bfimport(dataPath)
% MD = bfimport(dataPath, false)
% MD = bfim
    
function movieArgs = getMovieMetadata(r, iSeries)

import ome.units.UNITS.*;

% Create movie metadata cell array using read metadata
movieArgs={};
metadataStore = r.getMetadataStore();

% Retrieve pixel size along the X-axis
pixelSize = [];
pixelSizeX = metadataStore.getPixelsPhysicalSizeX(iSeries);
if ~isempty(pixelSizeX)
    pixelSize = pixelSizeX.value(ome.units.UNITS.NM).doubleValue();
end
