scala-smfsb

Scala library for stochastic kinetic modelling, biochemical network simulation, and parameter inference, associated with the 3rd edition of the textbook Stochastic Modelling for Systems Biology

• The current stable version of this library is "0.6"
• The current unstable snapshot release of this library is "0.7-SNAPSHOT"

Binaries are published to Sonatype, cross-built for Scala 2.11.x and 2.12.x.

Quickstart

• To use this software library, you should first install a recent JDK and Sbt.
• Run sbt from an empty/temp directory
• At the sbt prompt, enter:

set libraryDependencies += "com.github.darrenjw" %% "scala-smfsb" % "0.6"
set libraryDependencies += "org.scalanlp" %% "breeze-viz" % "0.13.2"
set scalaVersion := "2.12.6"
console

• You should now have a Scala REPL with a dependency on this library. At the Scala REPL, enter the following:

import smfsb._
import breeze.linalg._
val model = SpnModels.lv[IntState]()
val step = Step.gillespie(model)
val ts = Sim.ts(DenseVector(50, 40), 0.0, 20.0, 0.1, step)
Sim.plotTs(ts)

• This should simulate a trajectory from a Lotka-Volterra model and plot the result in a window on the console which looks a little bit like the following:

To get the most out of this library, it will be helpful if you are already familiar with the R package smfsb associated with the (2nd or) 3rd edition of the textbook Stochastic modelling for systems biology, and have a basic familiarity with Scala and Breeze. For those new to Scala, my course on Scala for statistical computing is a good place to start.

Documentation

• An introduction to scala-smfsb - a "taster" blog post
• Tutorial - walk through of basic functionality
• There are more interesting examples in the examples directory. To run them, download or clone the repo, and do sbt run from inside the examples directory.
• A blog post looking at stochastic reaction-diffusion modelling using the library
• Latest API docs

Using the library in your own Scala projects

giter8 template:

To create a new Scala sbt project template, just use:

sbt new darrenjw/scala-smfsb.g8

This will create a new project including a dependence on the stable version of the library.

Stable:

Just add:

"com.github.darrenjw" %% "scala-smfsb" % "0.6"

to your Sbt dependencies. You might also need to add an explicit dependence on breeze-viz:

"org.scalanlp" %% "breeze-viz" % "0.13.2"

Snapshot:

Just add something like:

libraryDependencies += "com.github.darrenjw" %% "scala-smfsb" % "0.7-SNAPSHOT"
resolvers += "Sonatype Snapshots" at
    "https://oss.sonatype.org/content/repositories/snapshots/"

to your Sbt build file.

Building from source

Download or clone the repo and do:

sbt clean compile test doc package

from the top-level directory.
