Most microarray analysis software packages all do the same tasks, they find the most
differentiated genes between two categories, make cluster
dendrograms, etc, etc.
Some of them even allow you to use knowledge resources like the Gene
Ontology to drill down deeper into the biological meaning of
your analytical results.
All this is valuable -- but ArrayGenius is different!
When microarray data is loaded into
ArrayGenius, the first thing it does is compare your data to
its internal ontologies -- built based on the Gene Ontology
and proteomic databases -- and create an enhanced
dataset. The enhanced dataset tells you the degree to
which various biological processes and protein families are
expressed in your dataset. ArrayGenius uses the
enhanced dataset along with the original one, in all its
subsequent analyses.
You can make cluster dendrograms -- both
the familiar kind where you see which genes cluster together
in the dataset, and a new kind, where you get to observe
which biological processes cluster together in the dataset.
And then things get really interesting....
A common situation is where microarray data samples can be divided into two or more
categories. These categories may be Case vs. Control,
they may represent different time points, etc. In this
sort of situation, you can ask ArrayGenius to learn
classification models -- mathematical rules that predict
whether a sample belongs to one category or another, using
the gene expression values in the sample and also the
inferred expression values of biological processes and
protein families in the sample. In many cases it finds
extremely accurate rules -- our studies show that, after a
bit of experimentation with parameter values, it generally
beats the best algorithms from the academic
literature. Sometimes these rules are surprisingly
simple, other times they're more complex.
Generally ArrayGenius will learn a lot of
classification models for a dataset, not just one or two --
and it can then study which genes, processes and families
occur most often across all its models. This is a
novel way of detecting which genes, processes or families
are most important to the biological phenomenon being
studied in the dataset. The most important features,
in this sense, will often not be the ones most
differentiated in expression between the categories of
interest. That's because ArrayGenius is figuring out
which genes, processes and families are most important, not
in terms of their solitary activity, but in terms of their
interactions with other genes, processes and families.
And once you've gotten your results, you
can interpret them via following hyperlinks into the Gene
Ontology database, into PubMed, into various other online
resources -- and into the BiomindDB, our own integrative
data resource that provides useful functions like finding
the research articles that focus on particular combinations
of genes and processes.
ArrayGenius's novel approach
provides a lot of information that more traditional
microarray analysis doesn't:
-
Ontological data integrated into the
analytical process, so that classification rules and
clusters involve biological processes and structures and
families, not just raw gene expression
values.
-
A sophisticated understanding of which
biological processes are important to the phenomena
under analysis
-
Extremely accurate classification
rules, useful for diagnostics and other purposes
New kinds of knowledge, indicating
biological relationships and research directions that would
otherwise go unnoticed. A smarter way to analyze
microarray data.
So you want to put the power of ArrayGenius
to work on your data -- what's the next step?
ArrayGenius is an enterprise product,
running on a small network of powerful Linux servers -- and
with a 100% Web-based user interface, accessible through any
Web browser.
If you want a dedicated ArrayGenius all for
yourself, we also offer a "Managed Hosting"
plan. This means we host, in our server farm, a secure
ArrayGenius installation that is entirely dedicated to your
data, firewalled off from other machines. This gives
you total privacy and dedicated processing 24-7, 365 days a
year. Again: no software installation required.
Each individual in your organization can make an account,
and log onto the site to upload or analyze data. It's
like having your own dedicated ArrayGenius OnDemand.
Finally, if you want to install ArrayGenius
in-house, we offer two options: purchasing the software and
installing it on your own Linux network, or purchasing a set
of machines with Linux and ArrayGenius preinstalled.
If you're interested in managed hosting or
an in-house installation, please email sales@biomind.com and one of our representatives will get back to you
promptly.
