Agent-based metabolic modelling of microbial communities in time and continuous µ-meter-scale space
Eutropia is a R-package for cell agent-based metabolic modelling of microbial communities. It allows dynamic simulations of two-dimensional surface-attached cell communities. A few features of Eutropia, that you might find interesting:
- Complex polygons (also non-convex) as growth environment
- Extracellular enzymes
- Nutrient regimes
- Chemotaxis (attracting and repelling)
- Direct calculations of community assortment and segregation (see e.g. Yanni et al. (2015) Current Biology)
Eutropia is in its development phase. The current development version can be installed using:
# install.packages("devtools")
devtools::install_github("Waschina/Eutropia")If you have not installed devtools yet, just uncomment the first line.
For an example simulation, please have a look at the package's vignette.
For the individual Flux-Balance-Analysis steps, Eutropia requires a LP-solver. Ideally, the GLPK (GNU Linear Programming Kit) together with the R-interface-package glpkAPI should work. If you like to speed up the simulations, you could consider installing IBM's ILOG CPLEX Optimization Studio along with the R-interface-package cplexAPI. If you are in academia, make sure to check out IBM's academic initiative. Installing the R-package cplexAPI can sometimes be a bit tricky, so we'd suggest to get the latest version here and following the install instructions.
