[ccp4bb] Postdoc position: structural biology of microtubule dynamics

2013-02-12 Thread Luke Rice
A postdoctoral position is available immediately in Luke Rice’s lab at the University of Texas Southwestern Medical Center in Dallas, TX. The Rice lab is broadly interested in questions relating to the molecular mechanisms of microtubule polymerization dynamics and the mode of action of regulato

You can do much the same with Aimless but I'm not sure about ctruncate. No access to documentation at present If the Is came from Fs by squaring them in Pointless then it is important not to truncate them, just square root them Phil Sent from my iPhone On 12 Feb 2013, at 19:46, Clemens Vonr

Hello, I have been looking for a tool to measure the "Protein accessible surface area", which could be defined exactly as the solvent ASA except with a probe of larger radius. Most tools that calculate ASA however do not work with a probe radius of a size equal to 10 or 50 Angstroms. Plus, ideall

Ah I'm not sure about that. It may be possible to tell ctruncate not to do this. Actually if you started with Fs you don't want to truncate the data. Maybe use old truncate with the notruncate option Phil Sent from my iPad On 12 Feb 2013, at 18:48, Ethan Merritt wrote: > On Tuesday, February

"Scale constant" in Aimless or Scala should do it. I should probably make that automatic. I should probably also add a CIF reader to Pointless. Is there a good (easy) C++ one out there? Phil Sent from my iPad On 12 Feb 2013, at 08:08, Jens Kaiser wrote: > Ethan, > The last time I attempt
