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: icatb_parBackReconstruct_cluster.m
    path of file: ./repos/gift/GroupICAT/icatb/icatb_parallel_files
    
    the code of the file until where you have to start completion: function varargout = icatb_parBackReconstruct_cluster(sesInfo, dataSetsToRun, verbose)
%% Back-reconstruct components in paral
    
function
    data = icatb_preproc_data(data, preproc_type, verbose);
    
    drawnow;
    
    if (~useTemporalICA)
        
        if (strcmpi(backReconType, 'spatial-temporal regression'))
            %% STR
            if (numOfSub*numOfSess ~= 1)
                
                % Dual regression
                [tc, spatial_maps] = icatb_dual_regress(data, icasig);
                
            else
                
                %% For single subject ICA temporal regression is avoided
                tc = pinv(icatb_remove_mean(icasig))*icatb_remove_mean(data);
                spatial_maps = icasig';
                
            end
