| 3 | +PySCeSToolbox |
| 4 | +============= |
| 5 | + |
| 6 | +This is a set of metabolic model analysis tools for PySCeS. |
| 7 | + |
| 8 | +PySCeSToolbox currently provides tools for: |
| 9 | + |
| 10 | +- Generalised supply-demand analysis. |
| 11 | +- Symbolic metabolic control analysis and control pattern analysis. |
| 12 | +- Generating model schemas from metabolic models. |
| 13 | +- Distinguishing between thermodynamic and kinetic contributions |
| 14 | + towards reaction rate. |
| 15 | +- Interactive plotting |
| 16 | + |
| 17 | +PySCeSToolbox was designed to be used within the Jupyter notebook, but |
| 18 | +most of the core features should work in a normal Python script. |
| 19 | + |
| 20 | +Documentation can be found at http://pyscestoolbox.readthedocs.org. |
| 21 | +While all major tools have been documented, the documentation is still a |
| 22 | +work in progress. |

| 36 | + |
| 37 | +An abbreviated list of requirements is given below. Python dependencies |
| 38 | +will be installed automatically when installing PySCeSToolbox via pip. |
| 39 | +For detailed operating system specific instructions on installing the |
| 40 | +requirements see the documentation at |

| 52 | +Required packages should automatically download and install when using |
| 53 | +the commands specified under `Installation <#installation>`__ below. |
| 54 | + |
| 55 | +Maxima is only a requirement for SymCA. |
| 56 | + |

| 59 | + |
| 60 | +The latest release of PySCeSToolbox can be installed from PyPi by |
| 61 | +running the following commands in the terminal (or Windows equivalent): |
| 62 | + |
| 63 | +.. code:: bash |
| 64 | +
|
| 65 | + pip install pyscestoolbox |
| 66 | +
|
| 67 | +The latest development version can be installed from GitHub with: |
| 68 | + |
| 69 | +.. code:: bash |
| 70 | +
|
| 71 | + pip install git+https://github.com/exe0cdc/ipython-d3networkx.git |
| 72 | + pip install git+https://github.com/PySCeS/PySCeSToolbox.git |
| 73 | +
|
| 74 | +For the pre-2015-11-11 version: |
| 75 | + |
| 76 | +.. code:: bash |
| 77 | +
|
| 78 | + pip install git+https://github.com/exe0cdc/ipython-d3networkx.git |
| 79 | + pip install git+https://github.com/PySCeS/PySCeSToolbox.git@f63b5ab660f103105750159885608a5f48de1551 |
| 80 | +
|
| 81 | +Basic usage |
| 82 | +----------- |
| 83 | + |
| 84 | +To start a PySCeSToolbox session in a Jupyter notebook: |
| 85 | + |
| 86 | +1. Start up the Jupyter Notebook using the ``jupyter notebook`` command |
| 87 | + in the terminal |
| 88 | +2. Create a new notebook by clicking the ``New`` button on the top right |
| 89 | + of the window and selecting ``Python 2`` |
| 90 | +3. Run the following three commands in the first cell: |
| 91 | + |
| 92 | +.. code:: python |
| 93 | +
|
| 94 | + %matplotlib inline |
| 95 | + import pysces |
| 96 | + import psctb |
| 97 | +
|
| 98 | +Model files must be placed in ``~/Pysces/psc/`` if using Linux or |
| 99 | +``C:\Pysces\psc\`` for Windows. |
| 100 | + |
| 101 | +Important notices |
| 102 | +----------------- |
| 103 | + |
| 104 | +For readers of "Tracing regulatory routes in metabolism using generalised supply-demand analysis" published in BMC Systems Biology on 03/12/2015: |
| 105 | +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 106 | + |
| 107 | +To use the IPython notebook file included as "Additional file 5" in the |
| 108 | +paper, please install the **latest version** of PySCeSToolbox specified |
| 109 | +under `Installation <#installation>`__. |
| 110 | + |
| 111 | +The two PySCeS MDL model files included as "Addition file 1" and |
| 112 | +"Addition file 2" are required to run the notebook. They should be |
| 113 | +renamed to "Hoefnagel\_moiety\_ratio.psc" and "Curien.psc", |
| 114 | +respectively. Further instructions are included within the notebook and |
| 115 | +on this page. |
| 116 | + |
| 117 | +Firefox users should download these files using a different browser or |
| 118 | +switch to the new beta version of the BMC Systems Biology website. |
| 119 | + |
| 120 | +Changes: |
| 121 | +~~~~~~~~ |
| 122 | + |
| 123 | +Because this project is still in its infancy, future changes might break |
| 124 | +older scripts. These types of changes will be kept to a minimum and will |
| 125 | +be documented here. |
| 126 | + |
| 127 | +Changes on 2017-02-09: Full cross compatibility |
| 128 | +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| 129 | + |
| 130 | +On 2017-02-09 Symca support via Maxima has been added to PySCeSToolbox |
| 131 | +on Windows. A configuration file located at |
| 132 | +``C:\Pysces\psctb_config.ini`` can be used to specify the path to |
| 133 | +``maxima.bat``. By default, however, PySCeSToolbox should detect the |
| 134 | +path to ``maxima.bat`` automatically if it has been installed using the |
| 135 | +default options. This change should have no impact on any older scripts |
| 136 | +save for making them platform independent. |
| 137 | + |
| 138 | +Changes on 2017-02-02: Dropped IPython Notebook 3.x.x support |
| 139 | +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| 140 | + |
| 141 | +As of 2017-02-02 IPython Notebook 3.x.x support has been dropped in |
| 142 | +favour of Jupyter 4.x.x. This should not affect the functioning of |
| 143 | +scripts (save for those based on versions before that of 2015-11-11). |
| 144 | +PySCeSToolbox will however require the Jupyter Notebook as of this date |
| 145 | +in order to use its interactive features. Note that ``ipywidgets`` (an |
| 146 | +automatically installed requirement for the Jupyter notebook) needs you |
| 147 | +to run the command |
| 148 | +"``jupyter nbextension enable --py --sys-prefix widgetsnbextension``" |
| 149 | +before enabling widgets in the notebook. |
| 150 | + |
| 151 | +Changes on 2015-11-11: API changes |
| 152 | +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| 153 | + |
| 154 | +Major changes were made on 2015-11-11 that might break scripts coded |
| 155 | +before this date. These changes are related to the naming of methods and |
| 156 | +fields. For scripts older than 2015-11-11 we recommend using an older |
| 157 | +version of PySCeSToolbox (noted under `Installation <#installation>`__). |
| 158 | +Manual porting of scripts is also possible with details of necessary |
| 159 | +changes outlined under `Porting scripts to latest |
| 160 | +version <#porting-scripts-to-latest-version>`__. |
| 161 | + |
| 162 | +Porting scripts to latest version |
| 163 | +--------------------------------- |
| 164 | + |
| 165 | +Method and variable names and the analysis objects they belong to that |
| 166 | +were changed on 2015-11-11 are documented in the tables below. To port |
| 167 | +any older script simply change the old name of any method/variable to |
| 168 | +the new name. |
