Project Description

Biopantograph is a collection of python modules and programs for the reconstruction, curation and validation of metabolic models. It reads and writes SBML files.

Installation

The recommended installation method is:

pip install biopantograph

Pantograph requires libsbml, but pip will take care of that requirement. If you don’t have permissions to install at the system level, try: pip install biopantograph --user. You can also clone and contribute from the BitBucket repository.

Tools

The basic script you need to know is pantograph, which will help you to reconstruct a metabolic model for your target species. pantograph takes as input an existing SBML model as a template, orthology data between your template and your target genes (from Inparanoid and/or OrthoMCL) and other optional data. Invoke pantograph as follows:

$ pantograph -x scaffold.xml -i inparanoid.data -m orthomcl.data -s org1 -t org2 -o out.xml -l out.log

Where `scaffold.txt` is an existing, well-curated SBML metabolic model, used as a template for the reconstruction; inparanoid.data is the output from Inparanoid, comparing the genes from the template and the reconstructed model; orthomcl.data is the output from OrthoMCL (where org1 is the template model id and org2 is the reconstructed model id); out.xml is the SBML reconstructed model and out.log is the reconstruction log. You can reconstruct a model using any of the two orthology methods (Inparanoid or OrthoMCL), although better results are obtained using both.

The biopantograph package includes many other tools that can be useful for your reconstruction. Try them with the parameter --help to obtain usage information.

Tool Description
pantograph Create a new model, from a template model and orthology files
ptg_addbiggreactions Add reactions from a list of BiGG ids, to a model
ptg_projector Create a new model, using an existing one as template
ptg_curateSBML Add new species/reactions to a model, from a CSV
ptg_inparanoid2rel Parses Inparanoid output for ptg_projector
ptg_omcl2rel Parses OrthoMCL output for ptg_projector

The modules provided can be used to develop your own applications:

Module Description
pathtastictools Algorithms to reconstruct metabolic models from a template
SBMLeditor High-level modifications to SBML models
BiGG Module to handle calls to the BiGG Web API
BiGG2SBML Add elements from BiGG API to a SBML file
SBMLutils High-level utilities

Biopantograph has been tested under Linux and OS X. For more information, please visit the official Pantograph website: http://pathtastic.gforge.inria.fr. More documentation coming soon!
