This repository provides access to the materials (code-data), software-environments (NetLogo, Rstudio, Docker containers), and the steps for reproducing the results from the publication: Modeling spatiotemporal domestic wastewater variability: Implications to measure sanitation efficiency.

The information below guides you to execute two NetLogo simulations. One represents a non-calibrated model, and the other is a calibrated and evaluated model. The main outputs are the figures and tables representing the results assessment of the mentioned publication.

Note: If you found this repository useful and would like to support reproducibility and open science, I would appreciate a star for this repository. You can also send an email if you could replicate the results. Your reaction is relevant for monitoring and maintaining this material.

Getting Started

Pre-requirements

Used computational environment:

Platform: x86_64-w64-mingw32/x64 (64-bit) 
Running under: Windows 11 x64 (build 22631)
Processor:  Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz   2.59 GHz
Logical processors: 12 
Installed RAM   32.0 GB (31.6 GB usable)
System type 64-bit operating system, x64-based processor

Docker Desktop v.4.16.3

R version 4.3.1 (2023-06-16 ucrt)
RStudio 2023.12.1

NetLogo 6.1.1
  1. Data:
  • Download or copy this repository to a local folder .
  1. Open-source software:

Quick reproducibility (requires NetLogo/Rstudio experience):

Long-term reproducibility (requires some familiarity with Docker):

  • Install and run Git Bash. See: https://gitforwindows.org/
  • Install and run Docker Desktop. See: https://www.docker.com/products/docker-desktop/
  • NetLogo note: Before building and running NetLogo images and containers in Docker Desktop consider that you can run the NetLogo models once you install NetLogo 6.1.1. Running NetLogo in Docker Desktop can take a couple of hours. Running NetLogo with your own NetLogo 6.1.1 installation can take around 25 minutes.
  1. Libraries and extensions:
  • NetLogo: The first time running the Netlogo file, you will get a windows to install the time extension. Follow the instructions to install it.
  • Rstudio: The first time that you open the R project execute the renv::restore() in the R console to load the required libraries. You can explore the library requirements in the renv.lock file.

Quick reproducibility

This section is for Windows users familiar with NetLogo, Rstudio, and Git bash. Mac or Linux users can also try to reproduce results. Jump to the long-term reproducibility (usage) section, which uses Docker to reproduce results as the alternative for non-experienced users.

Steps for a quick reproduction:

  1. In a new folder, execute the following commands in git bash:
git clone https://github.com/delapazruiz/domestic.wastewater.variability.git
. ./code/newfiles.txt
  1. Open the NetLogo (v. 6.1.1) files and run the experiments. In Tools/BehaviorSpace, change to 25 runs and select processors to run each experiment. (time: around 25 min each)
dw.sms.abm.snt.2020.cal.val.1.nlogo
dw.sms.abm.snt.2020.no.cal.val.1.nlogo
  1. Open the Rstudio project file and verify the library requirements.

R Project file:

domestic.wastewater.variability.Rproj

Make sure that 'renv' is installed and loaded.

install.packages("renv")

Load the 'renv' library.

library(renv)

Run the following in the R console to install the required libraries.

renv::restore()
  1. Open the R markdown file and knit it to generate the report: (time: around 25 min)
DW_ABM_before_after_calibration_and_validation.Rmd

Long term reproducibility

  • Open Git Bash in the folder path of the repository.

  • Execute the following command in Git Bash to set up new files to run NetLogo:

. ./code/newfiles.txt

Build NetLogo images

  • Open Docker Desktop and verify the engine is running (green icon at the left-bottom corner).

  • Execute the below commands in Git Bash to create NetLogo Docker images. Note that the two models must be created and run:

    • Model not calibrated, and model calibrated:
docker build -f DockerfileNetlogoNocalibration --build-arg MODEL_NAME=dw.sms.abm.snt.2020.no.cal.val.1.nlogo --build-arg NETLOGO_VERSION=6.1.1 -t dwsmsabmsntnocalibration .
docker build -f DockerfileNetlogo --build-arg MODEL_NAME=dw.sms.abm.snt.2020.cal.val.1.nlogo --build-arg NETLOGO_VERSION=6.1.1 -t dwsmsabmsntresults .
  • Verify that the following images were created. Go to Docker Desktop/images: dwsmsabmsntnocalibration & dwsmsabmsntresults.

Run NetLogo containers

  • Execute the below command in Git Bash to run the XPRA X11 tool.
docker run -d --name x11-bridge -e MODE="tcp" -e XPRA_HTML="yes" -e DISPLAY=:14 -e XPRA_PASSWORD=111 -p 10000:10000 jare/x11-bridge
  • Go to Docker Desktop/containers to verify that the container x11-bridge is running.

  • Run the calibrated and no calibrated models with the following steps:

Note that in the two commands bellow (1,7) you have to replace the 'my/directory/path/to/results' to your working directory. For example: 'my/directory/path/to/results' = C:/Mydocker.dwvariability/results.

  1. Execute the below command in Git Bash to run the container dwsmsabmsntnocalibration.
docker run -it -d -m 20024M -d --name dwnetlogonocalibration --volumes-from x11-bridge -v 'my/directory/path/to/results':/home/results dwsmsabmsntnocalibration
  1. Once the Docker container is running, open your web browser (e.g.B Chrome, Firefox) and paste the following URL in the search bar: http://localhost:10000/index.html?encoding=rgb32&password=111

You should see the NetLogo model.

  1. Press ctrl+shift+B to open the Behavior space menu and you should see the experiment: cal.val.1 (50 runs).

  2. Press Run. In Simultaneous runs in parallel type 2 or 3 processors and deselect all Run options.

Note: If you get the message running out of memory, go to containers in Docker Desktop. Stop and start again the container named dwsmsabmsntnocalibration to run again NetLogo and try 1 processor.

  1. Make sure that the NetLogo window Running Experiment: with a timer appears. Move the bar of normal speed to the right until showing fast. Processing time depends on the number of processors and computer features. For example, with 3 processors the simulation should take around 1:30 hrs.

  2. In Docker Desktop go to containers. Stop the dwsmsabmsntnocalibration container.

  3. To execute the following model container: dwsmsabmsntresults go to Git Bash and run the command:

docker run -it --cpus=12 -d -m 20024M -d --name dwnetlogoresults --volumes-from x11-bridge -v 'my/directory/path/to/results':/home/results dwsmsabmsntresults
  1. For the dwsmsabmsntresults container, repeat steps from 2 to 6.

You can refer to the following tutorial which shows a video to run NetLogo images in Docker:

Build RStudio image

  • In Git Bash execute the following command to create the Rstudio image in Docker Desktop.
docker build -f DockerfileRstudioDWresults -t dwsmsabmsnt2020rproj .
  • Verify that the following image was created. Go to Docker Desktop/images: dwsmsabmsnt2020rproj.

Run RStudio container

  • Execute the below command in Git Bash to run RStudio. Do not forget to replace your own working directory. For example: 'my/directory/path/to/results' = C:/Mydocker.dwvariability/results/calibration.snt
docker run -d --name dwrstudio -p 8787:8787 -e PASSWORD=mypassword -v 'my/directory/path/to/results':/home/rstudio/results/calibration.snt dwsmsabmsnt2020rproj
  • Go to Docker Desktop/containers to verify that the container dwrstudio is running. Open the following link in a web browser:

http://localhost:8787

  • Type the following credentials:
    username: rstudio
    mypassword: mypassword

  • In the RStudio user interface, go to files and open the R project file:

domestic.wastewater.variability.Rproj
  • Make sure that 'renv' is installed and loaded. Execute in the R console:
install.packages("renv")
  • Load renv:
library(renv)
  • Run the following in the R console to install and load the required libraries.
renv::restore()
  • In Files, Home, open the R markdown file and Press the Knit icon to generate the report: (processing time: around 5 min). Click 'Yes' to any 'Install or Update' emergent message.
DW_ABM_before_after_calibration_and_validation.Rmd
  • The viewer panel shows the results.

Expected results

Download the repository and open the file: DW_ABM_before_after_calibration_and_validation.html to see expected results after pressing Knit in RStudio.
