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: pspm_cfg_glm_rp_e.m
    path of file: ./repos/PsPM/src/pspm_cfg
    
    the code of the file until where you have to start completion: function [glm_rp_e] = pspm_cfg_glm_rp_e
% GLM RP E

% $Id$
% $Rev$

% Initialise
global settings
if isempty(settings), pspm_init; end;

% set variables

vars = struct();
vars.modality = 'RPR';
vars.modspec = 'rp_e';
vars.glmref = {['Bach, Gerster, Tzovara, & Castegnetti (2016) ', ...
    'Psychophysiology (Development of the GLM evoked RPR)']};
vars.glmhelp = '';

% load default settings
glm_rp_e = pspm_cfg_glm(vars);

% set correct name
glm_rp_e.name = 'GLM for RP (evoked)';
glm_rp_e.tag = 'glm_rp_e';
