Pathwave

About PathWave

PathWave enables the identification of disease specific regulation patterns by combining gene expression data and network topology. PathWave is preferable to classical enrichment tests as it offers a much higher sensitivity for detecting such functionally related regulation patterns. Additionally, it is more precise to a permutation based enrichment method (Schramm et al 2010).

CITING PATHWAVE: please cite Piro et al (2014) for PathWave version 2.1, Schramm et al (2010) for PathWave version 1.0, and both papers (Schramm et al 2010; Piro et al 2014) for PathWave in general.

PathWave version 2.1 (Piro et al. 2014):

The R package does already include all necessary data for BiGG/Human recon 1 (H. sapiens) and KEGG (H. sapiens, M. musculus, D. melanogaster, C. elegans, D. rerio, E. coli)

Additional software for PathWave version 2.1:

The following software is needed only to preprocess further pathway data sets from KEGG (KGML) or BiGG (SBML), not for applying PathWave to already available, preprocessed pathway data. Note: GridArranger is also included as external code in the PathWave 2.1 R package. We provide it here as an independent package because it may be useful for other purposes.

  • GridArranger v1.0 - used to arrange pathways into compact 2D lattice grids (see Schramm et al 2010; Oswald et al., 2012; Piro et al 2014).
  • GridArranger v1.0 README - basic information on installation and usage.
  • ABACUS v2.4-alpha - required by GridArranger; this package is provided with kind permission of the original authors at the University of Cologne, Germany, because newer versions of ABACUS (available at the ABACUS webiste) are not compatible with GridArranger.

PathWave version 1.0 (Schramm et al. 2010):
