Organisational Principles in Living Organisms

This Python package provides data structures to model and simulate the organisation at (unicellular) system scale.

  • Genetic regulation (pyorganism.regulation)
    • Analog and digital control (cf. [1])
    • Transcriptional regulatory network (TRN): directed transcription factor-gene interaction network
    • Gene regulatory network (GRN): directed gene-gene interaction network (projection of the TRN)
    • Gene proximity network (GPN): undirected gene-gene proximity network
    • Couplons (intersection between sigma factor's and nucleoid associated proteins' targets)
    • Functional clusters (GO)
    • Metabolic control (cf. [2])
    • Continuous control (cf. [3])
  • Metabolism (pyorganism.metabolism)
    • Metabolic systems
    • Network representations
    • Flux balance analysis (FBA)

Requirements

  • future for Python2/3 compatiblity
  • Cython
  • networkx
  • numpy
  • pandas
  • reading/writing SBML files requires libsbml or the PyPi package
  • FBA requires either:
    • Gurobi (currently the only working interface),
    • GLPK,
    • MOSEK,
    • or any other linear programming solver that you are willing to provide the Python interface for (like gurobipy or cvxopt).
  • KEGG interface requires SOAPpy
  • (pytables for HDF5 storage can be replaced by pickling of numpy objects)
