Package: xbob.db.mobio
This package contains the access API and descriptions for theMOBIO
Database. The actual raw data for
the database should be downloaded from the original URL. This package only
contains theBobaccessor methods to use
the DB directly from python, with our certified protocols.You would normally not install this package unless you are maintaining it. What
you would do instead is to tie it in at the package you need touseit.
There are a few ways to achieve this:You can add this package as a requirement at thesetup.pyfor your ownsatellite packageor to your Buildout.cfgfile, if you prefer it that way. With this
method, this package gets automatically downloaded and installed on your
working environment, orYou can manually download and install this package using commands likeeasy_installorpip.The package is available in two different distribution formats:You can download it fromPyPI, orYou can download it in its source form fromits git repository. When you download the
version at the git repository, you will need to run a command to recreate
the backend SQLite file required for its operation. This means that the
database raw files must be installed somewhere in this case. With optionayou can run indummymode and only download the raw data files for
the database once you are happy with your setup.You can mix and match points 1/2 and a/b above based on your requirements. Here
are some examples:Modify your setup.py and download from PyPIThat is the easiest. Edit yoursetup.pyin your satellite package and add
the following entry in theinstall_requiressection (note:...meanswhatever extra stuff you may have in-between, don’t put that on your
script):install_requires=[
  ...
  "xbob.db.mobio",
],Proceed normally with yourboostrap/buildoutsteps and you should be all
set. That means you can now import thexbob.db.mobionamespace into your scripts.Modify your buildout.cfg and download from gitYou will need to add a dependence tomr.developerto be able to install from our
git repositories. Yourbuildout.cfgfile should contain the following
lines:[buildout]
...
extensions = mr.developer
auto-checkout = *
eggs = bob
       ...
       xbob.db.mobio

...MOBIO protocolsThere were initially two protocols defined on the Phase 2 of the database,
which were called ‘female’ and ‘male’. Later on, the number of protocols
has increased, considering the additional data recorded using laptops, which
has led to 8 protocols.The two initial protocols ‘female’ and ‘male’ now correspond to the protocols
called ‘mobile0-female’ and ‘mobile0-male’, respectively. The training,
development and evaluation sets are indeed identical.However, if you want to use the same ZT score normalization files as in this
