OMERO.tables

OMERO.tables provide a way to efficiently store large, tabular results within OMERO. If you would like to find out more about the use of the OMERO.tables API, see OMERO.analysis

Requirements

If you would like to help test the Tables API, you will need the following installed:

• HDF5
• NumPy points to downloads at http://sourceforge.net/projects/numpy/
• PyTables (Some packages include HDF5)

Unix

PyTables is likely available from the package repository of your Unix-flavor. This includes Mac OS X (homebrew), Debian and Ubuntu (apt-get), CentOS (yum), and SuSE (yast). Here we’ve shown manual instructions using virtualenv.

Manually

$ virtualenv $HOME/virtualenv
$ uname -o -p
unknown GNU/Linux
$ gcc --version
gcc-4.8.real (Debian 4.8.1-9) 4.8.1

$ wget "http://www.hdfgroup.org/ftp/HDF5/current/src/hdf5-1.8.11.tar.gz"
$ tar xzf hdf5-1.8.11.tar.gz
$ cd hdf5-1.8.11
$ ./configure --prefix=$HOME/virtualenv
$ make
$ make install
$ export LD_LIBRARY_PATH=$HOME/virtualenv/lib
$ . $HOME/virtualenv/bin/activate
$ easy_install tables

Checking that it works

After that, the following should succeed:

% python

[GCC 4.8.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.

Once the required Python libraries are installed, starting OMERO will automatically start up the OMERO.tables service; there should be no need for further configuration or interaction.
