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: xASL_wrp_DCM2NII_Subject.m
    path of file: ./repos/ExploreASL/Modules/SubModule_Import
    
    the code of the file until where you have to start completion: function [x, PrintDICOMFields, dcm2niiCatchedErrors] = xASL_wrp_DCM2NII_Subject(x, matches, dcm2niiCatchedErrors)
%xASL_wrp_DCM2NII_Subject Run DCM2NII for one individual subject.

function subjectExport = xASL_imp_SubjectName(subjectID)

    % If a subject ID has a `_` or a `-` or something else, we need to get
    % rid of it in the directory name for BIDS, for the import of the
    % sourcedata we should still know about that though, which is why we
    % use a new variable for the subject ID directory export.
    
    subjectExport = xASL_adm_CorrectName(subjectID, 2);
    
    if ~strcmp(subjectID,subjectExport)
        fprintf(2,'Special characters in subject ID, changing %s to %s\n',subjectID,subjectExport);
