Dear Consortium Members and Affiliates,
We've been busy digging out the past couple of days and now, with the obligatory blizzard behind us, have some January news to pass along. We have a date for the February iMosflm webinar, a story on Martin Jinek from the University of Zurich, a software push that includes several updates and one new application, a note about CCP4 and Coot, and 6 new members to welcome.
In webinar news, we just posted Pawel Penczek's webinar on the challenges of single particle EM structure determination to our YouTube channel. Next in line is a presentation by Dr. Harry Powell from the MRC Laboratory of Molecular Biology, on iMosflm - a tool for data reduction.
Our January webtale features Martin Jinek, Assistant Professor from the University of Zurich. While his lab has a strong focus on the development of CRISPR technology, Jinek emphasizes his roots and continuing studies in basic science: the "chemical basis of life still fascinates me and drives my career.” Read the full story here.
January's software push includes new releases for Biopython, CCP4, EMAN2, Jalview, NMRPipe, and VMD and we have added iPython Notebook to our collection. More details are included in the Software Changes section below.
A note about Coot: Coot is now rolled into the default CCP4 installation, which means that users will now access the version of Coot (currently 0.8.1) available in the CCP4 package. If you wish to access a different version of Coot, please email email@example.com for instructions.
We have six new members to welcome for the month of January. Brian Kelch has become our fifth member from the University of Massachusetts Medical School, Janice Robinson our seventh from the University of Iowa, Andrew McCarthy and Stephen Cusack have joined from EMBL Grenoble, and we have our first members representing India: Ramaswamy Subramanian and Arati Ramesh from the National Centre for Biological Sciences, Bangalore. Welcome to our new members!
Biopython was updated to version 1.64. This version includes Bio.CodonAlign, a new experimental module that facilitates building codon alignment, new tree construction and consensus modules for Bio.Phylo, automatic downloads of NCBI DTD files for XML parsing in Bio.Entrez, support for Python 2.6, 2.7, 3.3, and 3.4, and a number of other improvements.
CCP4 had a big update to version 6.5. This release includes numerous updates and several new programs, including Privateer-validate, Feckless, chemoinformatics support for Refmac in the form of Acedrg v90 and LibG, Blend v0.5.10, and Crank-2.
In EMAN2's latest -- version 2.1 -- the developers proclaim no more BDB! and note improvements in ease-of-use, better infrastructure for single particle tomography, and gold-standard resolution for refinements with automatic filtration. They also note that version 2.1 files are not backwards compatible and that 2.0x files will need conversion.
iPython Notebook was added as a stand-alone application. iPython notebook is a web-based interactive computational environment that allows you to combine code execution, text, mathematics, plots, and rich media into a single document.
Jalview version 2.8.2 is now part of our default installation. This update includes an option to color RNA and protein secondary structures, improvements to pairwise alignment, new options for RNA pseudoknot annotation, along with many other improvements and bug fixes.
NMRPipe is now at version 20140803. No additional information is available.
VMD was updated to version 1.9.2, which includes a new built-in TachyonL-OptiX GPU-accelerated ray tracing engine, support for off-screen OpenGL rendering, and improvements to QuickSurf.
