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: test_dccnpath.m
    path of file: ./repos/fieldtrip/test
    
    the code of the file until where you have to start completion: function test_dccnpath

% MEM 1gb

    
function test_dccnpath

% MEM 1gb
% WALLTIME 00:10:00
% DEPENDENCY dccnpath
% DATA public

global ft_default
ft_default.dccnpath = [];

% remember the original directory
origdir = pwd;

hostname = gethostname();
if startsWith(hostname, 'DCCN') || startsWith(hostname, 'dccn')

  %% Alternative0: Finds the right path for users with access to DCCN storage, either on the compute cluster or on DCCN desktops

  filename = dccnpath('/home/common/matlab/fieldtrip/data/ftp/test/edf/testAlphaIR20170321-0.edf');
  if ispc
    if ~strcmp(filename, 'H:\common\matlab\fieldtrip\data\ftp\test\edf\testAlphaIR20170321-0.edf')
      error('dccnpath() does not find the right DCCN path')
    end
