There is a online version of VECTRI - Note!!! This is a very old release of the code v1.2.4, and is recommended for demonstration use only.

This development by the University of Cologne, which they refer to as the "Multi-Agency-System", allows the user to integrate the model for a single point location without the need to set it up on a local computer or desktop. The system has a number of pre-defined datasets for locations in west Africa, or if you have daily temperature and rainfall data for a location you wish to study, you may upload this to the site.

The interface allows the user to set all the available model parameters, and there is also a version of the Liverpool dynamical malaria model (LMM), to enable the user to make model intercomparisons.

You will need to click the link below to go to the site. Under "Multi Agency System", click "HEWS", and then you can choose VECTRI or LMM. Please refer all questions regarding this site to

Download VECTRI

VECTRI is a open-source model written in FORTRAN that is released under an open-source license. The system requirements are

  1. A PC with linux OS or a MAC with OSX
  2. GIT (to clone the software)
  3. GFORTRAN (to compile the software)
  4. NETCDF libraries (sudo apt-get install libnetcdf-dev)

  5. On linux: sudo apt-get install git gfortran libnetcdf-dev libnetcdff-dev

    On MAC with macports: sudo port install git gfortran libnetcdf-dev libnetcdff-dev

It is free to use and modify for non-commercial, scientific and educational purposes, but may not be distributed to third parties. Instead we kindly ask you to direct colleagues to this site so we can keep a record of who is using the code.
VECTRI is released with the usual disclaimer that the model is a research tool and comes with no support or guarentees and the authors bear no responsibility whatsoever for any loss, financial or otherwise, that may occur through its use.

All that the authors ask is that:

  1. You state the origin of the model in any work you publicize.
  2. You reference the Tompkins and Ermert 2013 manuscript in any article that uses the model, even in a modified form.
  3. That a copy of any article using the model is sent to the authors after (or preferably before) submission to add to the database here.
  4. If you are thinking to use the model in an international grant proposal that you consider inviting ICTP to collaborate if the grant conditions allow (VECTRI development speed relies on external funding opportunities).
  5. You have no objections to your institute being listed on the above maps of VECTRI users.

These simple requests are to justify to the funding agencies that support the ICTP institution and the EU that supports much of the project research that the model development is useful to the wider community.

If you wish to make further code developments and require the full source code, please fill out the form below, and I will send you instructions on how to clone the model. Please note I do not store any email addresses unless you wish to be added to the VECTRI newsletter mailing list (Only one or two emails per year!) - and I will never pass on your details to any third party.

VECTRI under windows

We frequently get asked if VECTRI is available to run under windows. To date, the model has only been used in a Linux environment. If you wish to install the model under windows, we suggest you try the following software installation procedure (click point text for links to relevant pages):
  1. Install CYGWIN, ensuring to tick options such as a text editor (e.g. EMACS) and useful plotting software such as R and python
  2. Install netcdf libraries
  3. Install GFORTRAN
Another possibility would be to install a Virtual Machine with mint or ubuntu under windows so you can run a direct form of linux without wiping windows. Here is a simple guide to installing a VM under windows
Please note we are presently not able to offer further advice or support concerning the operation of the model under windows.


Version 1.4.0 has now been released (May 2016) which corrects some minor errors to improve model behaviour at temperatures cooler than 20C and also includes a simple treatment of blocking and clinical immunity. The model now has a diagnostic of clinical cases per 1000 people.
