Dear Consortium Members and Affiliates,
And we're off. September is at its end and the pace has quickened around the Harvard campus. Here at SBGrid there's lots of new going on - the launch of our new website, a new version of our laptop installation script, new grant funding - along with our usual items of note: webinar updates, a glimpse into Doug Daniels's lab at the Broad Institute, six new SBGrid citations, several software updates, and three new members.
The new SBGrid website was launched a few days ago. We're still working out a few kinks, but are excited to have a new layout with improved functionality. Please take a moment to browse around and let us know what you think.
In conjunction with the new website, SBGrid also set up a new support forum where you can find quick answers to commonly asked questions. We encourage you to join or start a new discussion thread on any topic relevant to structural biologists. You can access the forum here or from the /Get Help/Support Forum link on our website.
We've recently finished a new version of our laptop installation script, which, true to it's name, will allow you to install a subset of the SBGrid software collection on your laptop. Follow these instructions to get started and contact us at firstname.lastname@example.org with any questions.
New grant funding just came our way from the NSF that will allow us to build some new tools for members and contributing developers. Our bibliography builder will make the chore of software citation as simple as a few clicks. Using our web interface, authors will be able to select the software titles used in their work and receive a complete list of relevant citations. With new software tracking scripts we also aim to provide developers with much needed information on how their applications are used. We'll keep you posted on the development of these new tools.
In webinar news, we just finished a two-parter featuring Christian Olsen, who demonstrated sequence analysis and molecular cloning functionality in the Geneious application. Part I of his webinar has already been posted to the SBGrid YouTube channel under the "Other Tools" playlist, and Part II will soon be added. While visiting be sure to take a look at some of the 40+ other videos we've posted, including the popular PyMOL (3100 views) and SAXS (2176 views) presentations.
In this month's SBGrid Tale we talked to Doug Daniels at the Broad Institute. Daniels has spent the last two years building a new protein science group at the Broad, focused on discovering new drugs for targets previously thought undruggable.
Citations for SBGrid's eLife paper recently appeared in publications from several member labs, including those of Titus Boggon (Yale), Catherine Drennan (MIT), Christopher Fromme (Cornell), Thomas Schwartz (MIT), Holger Sondermann (Cornell), and Navtej Toor (UC San Diego). Our special highlight for September goes to Navtej Toor for his Nature publication "Crystal structure of a eukaryotic group II intron lariat". A list of these and a selection of publications from other members are included below.
We just pushed out several software updates, including new versions of BUSTER, CCP4, EMAN2, Gromacs, MODELLER, PyMOL, and Schrodinger. Additional details are included in the software changes section below.
Three new members joined SBGrid during the month of September: Sebastian Klinge joined a growing group from Rockefeller University, Genaro Ramirez Correa became our fourth member at Johns Hopkins University School of Medicine, and we have one new institute to add to our member map, with the addition of Ramachandran Murali from Cedars-Sinai. Welcome to our new members!
With the release of version 3.4.2, 2dx has had it's first upgrade in two years. This version includes many new features, including support for OSX 10.9 and 2d difference mapping, and goes after bugs, fixing many and creating a new tool to track them down.
BUSTER version 2.10.2 was pushed out this month. This update includes many improvements and fixes along with several new tools: Rhofit, buster-report, and Pipedream.
CCP4 6.4.0 was updated to include patches 20 and 21, which correct an OMP problem, allow an update to the new MrBUMP, and fix a maddening XDS-Pointless assertion error bug.
The latest from EMAN2, now at version 2.1, brings big improvements in stability and the addition of e2refine_easy, a primary single particle refinement program. Other enhancements include a new 3-D viewer and conversion options for Relion or Frealign for comparative refinement.
MODELLER version 9.14 fixes a number of bugs and most notably adds support for the new PDB format.
PyMOL was updated to version 184.108.40.206, which fixes an issue with volume carving.
Schrodinger 2014-3 includes improvements to the Maestro GUI and new tight core constraints for Glide -ligand and -induced fit docking.
Included below is a selection of publications that have appeared from Consortium member laboratories over the past 30 days. For the full list of publications please visit the Member Publications page on the SBGrid website.
