Can someone tell me about the kind of data representation that
OpenBiomind has to handle? I am interested in extending OpenBiomind to
support 1-2 different types of neural networks but my concern is about
special encoding requirements needed to present input to the network.
I understand the standard techniques for converting data to numerical
values (when needed) and performing normalization but does biological
data have any special requirements?

OpenBiomind has its own particular data format, which is described in
the OpenBiomind online docs, but there's nothing super-special about
it. Lucio could fill you in on the details.

Normalizing and "de-noising" biological data is often a **big deal**
-- a "black art" as they say -- and is particular to each type of data
...

For instance, if you want to apply OpenBiomind to MEG data, a lot of
the work will be figuring out the right preliminary transformations to
perform on the MEG data before feeding it into OpenBiomind...

We spent a lot of time playing with approaches to microarray data
normalization...
