1. Debian Med in 2011
Steffen Möller
for the
Debian Med Community
Bioinformatics Open Source Conference
Vienna, 2011
2. The Challenge – a technical view
● Increasing specialisation of tools and databases
● Access to larger number of resources
● Frequent external updates
● Increase in local administrative work
● Project-specific installations
● Differential or Meta-analyses
● Increasing platform diversity
● Local vs cloud
● Local vs mobile
3. The Challenge – a community
perspective
● Work sharing
● Somebody somewhere has installed what you are about to install
● Packaging is tremendously helpful even when you do it just for yourself
● The distribution of such packages allows other researchers profit from your effort
● Skill sharing
● Not everyone knows how to install everything correctly
● Tutorials / Mailing list discussions shall refer to identically installed packages
● Collaborative Outreach
● Computational biologists get instant access to software packages
– Working out of the box
– Compiling out of the box
● Debian Med has professional non-scientists sending patches to the researchers
4. Science and the role of a Linux
Distribution
● Publication of findings
● World-wide distribution of methods
● Authorships and publications are forwarded in package
descriptions
● Collaboration
● Software packages “meet” in the distribution
● Availability of source code as invitation to contribute
● Education
● Reach out to students at every level
● No black boxes
5. “What is special about Debian (Med)?”
● We are not special
● active support of downstream distributions, e.g. Ubuntu
● the converse
● Debian can be you!
● open to everyone
● training “on the job” to get your packages in
● finding volunteers to maintain packages for you
● Med Community support
● shared package maintenance via subversion / git
● portal to bug reports, biological packages
● “ontology-like” tagging of packages
6. What happened since BOSC 2010
● Many new packages
NGS (qiime), Ensembl, Blast+, gbrowse
● Many updates
Autodocktools, BALLView, Bio*
● Many new contributors
● Many new users
● Bio Cloud environments using Debian
● GSoC project for “Cluster in Cloud” worked with Torque
● Basic cloud images with Debian/Ubuntu became a commodity
● Debian Med Sprint on Bioinformatics (January)
● Closed loop for packaging with NERC Bio-Linux
● Close ties with Taverna and Eagle Genomics
7. Steady increase in new users
● Showing Debian graphs from popcon.debian.org, for
Ubuntu multiply by 8
● An average package is installed more frequently than
there are participants at BOSC+ISMB together
● Separate listing of recent installations / recent use
R/qtl ~700
clustalw ~240
mafft ~240
8. Inter-institutional team building
● Maintenance by active contributor to source code
● true interest in bug reports
● barrier free talking to providers of external libraries
● immediate feedback on incompatibilities
● Community
● influx of skills with every package supported
● volunteers address the details in packaging work
– Translations
– Format changes ...
● fluent transition between power user and developer
● appeal to volunteers
– Packages can be immediately modified and rebuilt
– Students at all levels and non-scientists may contribute
9. Ongoing development
● Packaging of classical Java developments
● Taverna's build dependencies still are not all in Debian – not in the right
version, this means
● similarly for Jalview – Java is difficult because of jar files shipping with
source code
● Establishment of complete workflows
● closing gaps on tutorials
● packages missing for
– In silico docking
– Automated genome assembly and annotation
● Data management
● BioMaj – very nice GUI application
● getData – may be first to link data with Debian packages
10. “Not even source” packages
● Some tools like VMD or Rosetta are surprisingly not in Debian, even
though they allow the download of source code
● But they don't allow to redistribute anything, which is sad since these
tools are not straight-forward to compile
– Compiler version likely to be newer than expected
– Libraries like BOOST may have deprecated a function
– Source code may require patches that are only found in discussion forums
● Debian Med hence hosts only the automated build instructions
● Ironically, this “not even source” concept was first adopted by CERN,
where they have Debian packages for their particle analysis tools - in
reaction to the BOSC abstract
11. What's next
● We need those problem solving workflows running
smoothly
● Hoping to bring the Medical and Biological parts of
Debian Med closer together
● Ontologies (nothing in Debian yet, again it's Java) and
reasoning
● Phenotyping of individuals and respective data
management
● Finding more bioinformatics groups already using
Debian (or its derivatives) to help reducing
redundancies and work with us all
