Re: [ccp4bb] To scale or not to scale: XDS_ASCII.HKL input to POINTLESS/AIMLESS

2014-11-17 Thread Graeme Winter
Dear Nukri, The following is my opinion which I think is worth discussion, and are based on my understanding of what XDS does in the CORRECT step. Firstly, I tend to find the global refinement in the CORRECT step useful for getting a good unit cell recycling the orientation matrix etc. for

Not very easily without more information.. The conversion does two steps - the first is scalepack2mtz which is meant to generate an mtz file ( /tmp/gouri/tvpsat_akg_1_1_mtz.tmp). Can you see if that ran correctly? Ekleanor Dodson On 17 November 2014 07:10, rohit kumar rohit...@gmail.com wrote:

Actually Pointless knows that the INTEGRATE file is corrected for an unpolarised beam and recorrects for a synchrotron unless the wavelength is one of the home source ones. See docs. You can specify explicitly I think Phil Sent from my iPhone On 17 Nov 2014, at 09:44, Graeme Winter

HI Phil, Yep: I was not clear perhaps but I did say this: Pointless will also do this but assumes unless given a correct value that the beam is quite polarized. Mostly: care needs to be taken, particularly if using a wavelength which may be confused with a lab source... For others: if you do

[ccp4bb] Dyes for DNA crystals

2014-11-17 Thread Rafal Dolot
Dear All, Sorry for non-CCP4 question. I'm looking for some dyes, like Hampton IZIT, suitable for DNA crystals and, of course safe for crystals. Is IZIT useful for that application? As I read, it is recommended for macromolecular crystals. What about Jena Bioscences dyes? Thank you for some

Re: [ccp4bb] How to run CCP4 without source command

2014-11-17 Thread David Waterman
Hi all, Folmer's advice is exactly right. However, just for the curious I'd like to point out a way to run CCP4 programs without having to explicitly source a setup script. For example (and for demonstration purposes, ignoring the fact that $CCP4 is only defined when the environment is sourced)

[ccp4bb] A Moleman alternative?

Dear all, I have no access to Moleman now but I need to compile a statistics table for a structure, more specifically, for its atom numbers (protein/ligand/water), B factors, RMS deviations etc. Is there an alternative program for that in the CCP4 suite? Thank you in advance for your help, -yong

[ccp4bb] B-factor blurring

Dear all can anyone help me with literatures references to B-factor blurring as a technique to reveal low resolution features in an electron density map? I have seen the poster from Andrea Thorn at http://shelx.uni-ac.gwdg.de/~athorn/pdf/thorn_iucr2014_poster.pdf but was wondering if there
