Bio-y (pronounced "bio-ee") The adjective form of the noun "Bio"

Some functions require the following python packages:
And other require external programs, including:
To install bioy and python dependencies, run setup.py or pip from the project directory::
% cd bioy % python setup.py install
% pip install -U .
If you don't want to install the dependencies (numpy and pandas take a while to compile), use::
% pip install --no-deps -U .
Numpy and pandas require many dependencies to compile (and you'll likely need to compile them because versions in package managers are typically out of date). Fortunately, these can pretty easily be installed on Ubuntu 12.04 by running::
% sudo apt-get build-dep python-numpy python-pandas
A virtualenv containing a complete python execution environment can be
created using dev/bootstrap.sh::
% dev/bootstrap.sh -h Create a virtualenv and install all pipeline dependencies Options: --venv - path of virtualenv [bioy-env] --python - path to the python interpreter [/usr/local/bin/python] --wheelstreet - path to directory containing python wheels; wheel files will be in a subdirectory named according to the python interpreter version; uses WHEELSTREET if defined. (a suggested location is ~/wheelstreet) [] --requirements - a file listing python packages to install [requirements.txt]
The bioy script provides the user interface, and uses standard
UNIX command line syntax. Note that for development, it is convenient
to run bioy from within the project directory by specifying the
relative path to the script::
% ./bioy
Commands are constructed as follows. Every command starts with the
name of the script, followed by an "action" followed by a series of
required or optional "arguments". The name of the script, the action,
and options and their arguments are entered on the command line
separated by spaces. Help text is available for both the bioy
script and individual actions using the -h or --help options::
usage: bioy [-h] [-V] [-v] [-q]

We use abbrevited git sha hashes to identify the software version::
% ./bioy --version 0128.9790c13
The version information is saved in bioy_pkg/data when setup.py
is run (on installation, or even by executing python setup.py -h).
Unit tests are implemented using the unittest module in the Python
standard library. The tests subdirectory is itself a Python
package that imports the local version (ie, the version in the project
directory, not the version installed to the system) of the
package. All unit tests can be run like this::
% ./testall

Ran 11 tests in 0.059s
OKA single unit test can be run by referring to a specific module,
class, or method within the tests package using dot notation::
% ./testone -v tests.test_utilsTo build the Sphinx docs::
(cd docs && make html)
And to publish to GitHub pages::
ghp-import -p docs/_build/html
(ghp-import and Sphinx are both included in the requirements.txt)
