PtCut -- Compute Tropical Prevarieties of Polynomial Systems
Copyright 2017-2019 Christoph Lders


This archive contains the source files of PtCut, a program to calculate the
tropical prevariety or equilibration of a system of polynomial equations. It
is freely available under the GNU Lesser General Public License (Version 3),
see COPYING.txt and COPYING.LESSER.txt.

PtCut is written for Python 2.7 & 3.x. It requires PPLpy to run, but works
also with SageMath, a free computer algebra system. Pre-compiled wheels of
PPLpy are also provided, see http://www.wrogn.com/ptcut.


Files:

ptcut.py -- the main program.

ptcut.pdf -- So far, there is not really a documentation.  Some parameters are
described here.  The rest must be clawed from the source code.

CHANGES.txt -- a list of recent changed.

db\* -- subdirectory with some parsed models from the BioModels database.
Here you can add your own models as well.
