How to use MultiMalModPy

This page provides an overview of the process steps

Define a simulation

  1. Open setup_sim.py and modify parameters as needed (visit building scenarios for details).

Running a simulation

  1. Open a terminal and navigate to the repository: 
cd ~/MultiMalModPy
  1. Run the Python script to define and launch the simulation: 
python launch_sim.py

This executes a test run using the default settings specified in the script and parse_launch_args (see helper.py).

  1. Wait for simulations to finish: Once the simulations complete, analyzer scripts and default plots will automatically be generated.

Example submission lines

  • Testrun: Run a quick test with predefined settings:

  • python launch_sim.py --models EMOD MalSim OpenMalaria --test

  • Baseline run: Run simulations with default settings or modified defaults from the Python file:

  • python launch_sim.py --models EMOD MalSim OpenMalaria

  • python launch_sim.py --models EMOD MalSim OpenMalaria --rownum 0 --csv baseline_eirsweep_noCM

  • Custom run: Run a simulation with specific interventions and test settings:

  • python launch_sim.py --models EMOD MalSim OpenMalaria --intervention cc_step --test --emodstep burnin
  • python launch_sim.py --models EMOD MalSim OpenMalaria --rownum 0 --csv cc_step_test

Example outputs

Time-series:

  • mmmpy_yr.csv: Age-bin specific key malaria outcomes* over time aggregated by year
  • mmmpy_mth.csv: Age-bin specific key malaria outcomes* over time aggregated by month-year
  • mmmpy_5day.csv: Age-bin specific key malaria outcomes* over time aggregated by 5days-year

Aggregated times for relationship and seasonality trends:

  • mmmpy_timeavrg.csv: Age-group specific key malaria outcomes and transmission outcomes*, aggregated over whole monitoring period

Additional output files:

  • EIR.csv, EIR_yr.csv, EIR_mth.csv and EIR_daily.csv: All age simulated EIR (added to benchmark output csvs)

Standardized output measures

Column Description EMOD malariasimulation OpenMalaria
index unique identifier (scenario * seed) Assigned as tag in the simulations Assigned to csv scenario file name Assigned to xml scenario input file names
(input)
date Simulation time converted to calendar dates Simulation start date + days that passed in the simulation Simulation start date + days that passed in the simulation days = survey * 5
date = year & month & ‘1’ for monthly aggregation)
month = days/365.0001/12
year = days/365.0001
year Simulation time to calendar year daily timesteps/365 daily timesteps/365 73 5-day timesteps
ageGroup Age of human host population Additional age aggregation performed for custom broader age groups specified by user Age groups to write out specified in reporter,
can be different from the agebins defined to specify demography		 Rendering of age groups need to be specified for each outcome,
can be different from the agebins defined to specify demography		 Age groups that are written out are the same as defined age bins in the demography section.
nHost human host population Input population size is used as scaling factor for population size defined in the demography file
‘Average Population by Age Bin’		 Input population size is written into corresponding R parameter Population is written out per index and age group n Input population size is written out per index and age group
measure 0-‘nHost‘
prevalence Proportion of individuals with patent infections Based on microscopy with defined diagnostic threshold, written out per index, time, age bin
‘PfPR by Age Bin’		 Calculated from n_detect/ nHost per index, time, age bin secondary outcome Calculated from nPatent / nHost per index, time, age bin secondary outcome
prevalence_2to10 Proportion of individuals with patent infections in 2-10 year olds As above, written out for age 2 to 10 (separate outcome in model)
PfPR_2to10		 Rendered separately for age 2 to 10 (separate outcome in model) (?) As above, calculated mean across prevalence of individuals aged 2 to 10 years
clinical_incidence Number of clinical cases per person per year (ppy) Written out per index, time, age bin
Annual Clinical Incidence by Age Bin		 Calculated from n_inc_clinical, nHost and reporting interval
secondary outcome		 Calculated from nUncomp, nHost and reporting interval
secondary outcome
severe_incidence Number of severe cases per person per year (ppy) Written out per index, time, age bin
Annual Severe Incidence by Age Bin		 Calculated from n_inc_severe, nHost and reporting interval
secondary outcome		 Calculated from nSevere nHost and reporting interval
secondary outcome
Simulated EIR Simulated EIR - Time unit corresponds to the same as of the output file (daily, monthly, yearly)
n_infectious_mos Number of infectious mosquitoes
n_total_mos_pop Number of host-seeking mosquitoes

Customize figures

Each existing plotting script allows users to define how outcomes are displayed, including colors, columns, and axes.
To customize figures, modify the respective plotting scripts directly.

Adding new figures

Users can add custom plotting scripts to the plotter subdirectory.

⚠️NOTE: Use filenames that start with `plot_` for consistency and easier integration into the framework.

Example usage:

python plotter/plot_custom1.py  --models EMOD malariasimulation OpenMalaria
