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: aas_delete_doneflag.m
    path of file: ./repos/automaticanalysis/aa_engine
    
    the code of the file until where you have to start completion: %%==============================
% Delete done flags
% function aas_delete_doneflag(aap,stage,inpi,inpj)


    
function aas_delete_doneflag(aap,stage,inpi,inpj)

function aap=aas_delete_doneflag(aap,stage,inpi,inpj)

% allow full path of module to be provided
[stagepath stagename]=fileparts(aap.tasklist.main.module(stage).name);
index=aap.tasklist.main.module(stage).index;
% retrieve description from module
description=aap.schema.tasksettings.(stagename)(index).ATTRIBUTE.desc;
% find out whether this module needs to be executed once per study, subject or session
domain=aap.schema.tasksettings.(stagename)(index).ATTRIBUTE.domain;

if (~exist('inpi','var'))
    boti=1;
    topi=length(aap.acq_details.subjects);
else
    boti=inpi;
    topi=inpi;
end
