To provide freely available, open-source software technology that broadly enables network assembly, analysis, visualization and network-based biomedical discovery for NIH-funded researchers.
These tools are enabling researchers to assemble large-scale biological data into models of networks and pathways and to use these networks to better understand how biological systems operate under normal conditions and how they fail in disease.

Technology Projects
Questions:
How are we doing? Strengths and weakness?
Where would you want to see these projects in several years?
Are there key network tools that we should be developing yet are not?
Are there network tools we are developing which are not so exciting?

Dynamic management of TRDsTRD projects•These projects should present compelling research and development opportunities for NRNB. • TRDs should be coupled to new or existing DBPs. • They should represent significant improvements to critical tools and resources for the research community. • We would provide (or fund) developer time to develop or enhance a novel tool or resource, defining a 2-5 year TRD project. • They should be assessed competitively each cycle with other new proposals and proposals for continuation of ongoing TRD projects.

Functional Overview
• Milestone 2 release just completed.• All core plugins except "Advanced Network Merge" have
been ported.• Cytoscape 3 is functional, but there are lots of bugs and the
code hasn't been tuned for performance.
![Page 27: NRNB EAC Report 2011](https://reader033.vdocuments.site/reader033/viewer/2022052410/554e798ab4c905f66a8b4fdb/html5/thumbnails/27.jpg)
Why we needed to redesign the API!
![Page 28: NRNB EAC Report 2011](https://reader033.vdocuments.site/reader033/viewer/2022052410/554e798ab4c905f66a8b4fdb/html5/thumbnails/28.jpg)

Architecture Status
• Still using OSGi for modularity.• Still using Spring-DM to configure modules.• Still using Maven to build and pull everything together.
• We now have a "simplified" plugin API. o You only need to know basic Java.o Just like in 2.X, you extend a single abstract class.
• So far, everything is behaving as planned.o The application starts correctly, services get registered,
APIs are public, implementation is hidden, plugins start, etc..
![Page 30: NRNB EAC Report 2011](https://reader033.vdocuments.site/reader033/viewer/2022052410/554e798ab4c905f66a8b4fdb/html5/thumbnails/30.jpg)
Documentation Status
• Lots of documentation written on the Wiki:o Overview of the Architectureo Overview of the APIo Plugin Developer's Guideo Plugin Porting Hints
• A Plugin Developer's tutorial has been added to OpenTutorials
![Page 31: NRNB EAC Report 2011](https://reader033.vdocuments.site/reader033/viewer/2022052410/554e798ab4c905f66a8b4fdb/html5/thumbnails/31.jpg)
Next Steps
• Fix known bugs.• Add missing features.• Analyze and address performance bottlenecks.• Re-evaluate API.• Ensure that proper OSGi metadata is being published.
• Refactor build system to that development code - compile - test cycle is faster.
• Refactor build system so that release generation is easier.
• Help plugin developers port plugins.

Collaboration and Training
• Collaboration and training• Win win: collaborators learn network and pathway
analysis, we learn about community needs
• 37 Collaborations and service projects (CSP)• Project management
– Services e.g. training, dissemination– Target # of CSPs?
• Balance of R&D and collaborations

Services NRNB should provide to select CSPsOrganizational
• Impact: Measure impact of project - e.g. track relevant publications and collaborations
• Interface: identify related resources, project and programs; facilitate new collaborations; hold joint conferences
• Host: link to project download, documentation and tutorial pages from nrnb.org• Advisory: provide recommendations and proposals to project leads regarding
technical development aims and organizational opportunitiesTraining
• Tutorials: prioritize, produce and promote tutorial materials; organize events • Feedback: collect and organize feedback from training events to share with
developersCommunity
• Events: organize, promote and staff lectures, tutorials and workshops• News: highlight news items related to the project and project leads• Communication: coordinate discussion lists, help desk, Facebook, Twitter, etc• GSoC: support project ideas, mentors and students in annual Summer of Code
program sponsored by Google• Retreat: organizing the annual retreat for project in conjunction with Cytoscape and
NRNB

Dynamic management of TRDs and CSPsCSP projects• The NRNB should continually engage in new Collaborative and Service projects which should be highly relevant to network biology and represent the “best in class.” • They should have demonstrated stability and a designated point-person for NRNB collaboration. • There should be obvious and direct synergy with existing NRNB projects. • We should take on such projects as a long-term commitment. • We will commit to providing a set of services to the user and development communities, ranging from organizational to training to communications.

Training and Outreach
1. Launched new NRNB website
2. Redesigned Cytoscape website
3. Launched new tutorial system, Open Tutorials
4. Out training events, presentations and GSoC
![Page 41: NRNB EAC Report 2011](https://reader033.vdocuments.site/reader033/viewer/2022052410/554e798ab4c905f66a8b4fdb/html5/thumbnails/41.jpg)
4. Handling requests for external training events
What to do with requests for external training support? We send staff, our “Roving Engineer” We provide tutorial materials through OpenTutorials,
(including customizable online content, slideshows, and handouts)
Proposal: Sponsor travel and accommodations for a number of external personnel to attend the annual Cytoscape Retreat. We would use the opportunity to “train the trainers” and thereby multiply our outreach capability with efficient investment of resources.
