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: bspm_slicetime.m
    path of file: ./repos/bspm/prepoc
    
    the code of the file until where you have to start completion: function matlabbatch = bspm_slicetime(in, dcmfile, opt)
% BSPM_SLICETIME
%
%   USAGE: matlabbatch = bspm_slicetime(in, dcmfile, opt)
%
%   opt:    1 = enter as slice order
%           2 = enter as slice times (e.g., for multi-band acquisitions)
