The general purpose `diffuStats`

R package offers a collection of seven network propagation scores and five graph kernels.
Those find application in ubiquitous computational biology applications, being one representative example the propagation of genetic information (e.g. disease-associated genes) in a gene-gene or a protein-protein interaction network.
A distinctive feature of `diffuStats`

is the implementation of statistically normalised scores, which address the recurrent question of how would the propagation of a randomised input look.
It offers parametric, exact z-scores as well as permutation-based empirical probabilities.

The `diffuStats`

software was published in:

Picart-Armada, S., Thompson, W. K., Buil, A., & Perera-Lluna, A. (2018). diffuStats: an R package to compute diffusion-based scores on biological networks. Bioinformatics, 34(3), 533-534.

General guidelines on how to choose the scores, along with mathematical properties of the normalised and unnormalised scores, were published in:

Picart-Armada, S., Thompson, W. K., Buil, A., & Perera-Lluna, A. (2020). The effect of statistical normalisation on network propagation scores. Bioinformatics, btaa896.

From versions 1.10.2/1.11.2 onwards, `diffuStats`

provides functions to export the exact statistical moments (means and variances), see `?moments`

.
Now the users can characterise the systematic biases in the diffusion scores in their domain of application.

`diffuStats`

is part of Bioconductor, and can be installed using

```
BiocManager::install("diffuStats")
```

For the development version, you can also install the package through `R CMD INSTALL`

or through `devtools::install_github("b2slab/diffuStats")`

, which points to its GitHub repository.

`diffuStats`

is suitable for medium-sized networks (thousands of nodes) and is conceived to be used in biological networks.
Its limitations come from the kernel formalism: networks exceeding 20k nodes will start requiring large kernel matrices in memory.

Get started by looking at the package vignettes (`intro`

for a quickstart, `diffuStats`

for a complete documentation) or its help

```
?diffuStats
