Release of libsoc (0.6) with ability to reference PharmML files

posted Jan 13, 2018, 5:33 AM by Maciek J Swat

We are happy to announce that a new version of libsoc (0.6), the R package for reading and writing SO files, has been released to CRAN, provided by Rikard Nordgren from Uppsala University.

The most important addition is functions to use a referenced PharmML to get information on types of parameters, i.e. if a parameter is structural, connected to residual variability or parameter variability, if a parameter is a correlation and which random variable (ETA) a variability parameter is connected to. Read examples in the new vignette (see link below). The latest version of nmoutput2so (4.7.12) has  an option (-generate_pharmml) to generate a minimal PharmML with information on the parameter model to be used by libsoc.

First release of pharmmlutils (pharmmltool)

posted Aug 22, 2017, 7:01 AM by Maciek J Swat   [ updated Aug 22, 2017, 7:02 AM ]

We are happy do announce the first release of pharmmlutils by Rikard Nordgren (Uppsala University), that currently contain pharmmltool. pharmmltool is a utility to validate PharmML 0.8.1 and 0.9, convert from PharmML 0.6 to 0.8.1 or 0.9 and 0.8.1 to 0.9.
It can also strip spaces, add indentation and print the version of a PharmML file. See the README for more details.

Packages for Linux, Mac and Windows can be found at https://github.com/rikardn/libpharmmlcpp/releases

An application note on ProbOnto 1.0 has been accepted for publication in Bioinformatics!

ProbOnto stands for 'Ontology and Knowledge Base of Probability Distributions' and has following features:
  1. Over 80 uni- and multivariate distributions and alternative parameterisations.
  2. Probability density or mass functions and where available cumulative distribution, hazard and survival functions.
  3. Supports encoding of univariate mixture distributions.
  4. Over 130 relationships and re-parameterisation formulas.
  5. Related quantities such as mean, median, mode, variance.
  6. Parameter and support/range definitions and distribution type.
  7. Latex and R code for mathematical functions.
ProbOnto has been in use in PharmML since version 0.7.1.

PharmML - Europe's 'top' markup language

On Thursday, September 10th, PharmML logo was spotted on Mont Blanc, 4810 m, see 'Home' page. We had temperatures about -12C but otherwise great weather which made it possible. Back to the office now and working on the next release.
