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: CBIG_ICCW_KRR_example_wrapper.m
    path of file: ./repos/CBIG/stable_projects/predict_phenotypes/ChenOoi2023_ICCW/examples
    
    the code of the file until where you have to start completion: function CBIG_ICCW_KRR_example_wrapper(out_dir)

% CBIG_ICCW_KRR_example_wrapper(out_dir)
%
% This function generates
    
function
CBIG_KRR_workflow_LITE( fullfile(param.outdir, 'setup.mat') )

%% STEP 2: run interpretation
% load results
load(fullfile(param.outdir, 'final_result_2cog.mat'))

% extract lower triangle of FC
FC_vec = zeros(780,50);
lt = logical(tril(ones(40,40),-1));
for subs = 1:size(corr_mat,3)
    FC_tmp = corr_mat(:,:,subs);
    FC_vec(:,subs) = FC_tmp(lt);
end
