Re: [ccp4bb] How many twinned crystals?

Crystals with messy spots smeared out in one direction with sometimes more than one maximum are probably better described as split crystals rather than twins, but if the splitting of the spots is clear enough the same procedures can be used to integrate them. George Prof. George M. Sheldrick

[ccp4bb] ESRF Rolling access beamtime

Dear all, The ESRF is pleased to remind you about the procedure for applying for rolling access beamtime on its MX beamlines. The rolling access procedure is designed to improve access to ESRF MX beam-lines and encourage the use of ESRF facilities by smaller groups working in the MX field.

[ccp4bb] xplot84driver problems

Hi, I've installed CCP4 on an Intel Mac running Mac OS X 10.4.10 using the binary installer from the automatic download page. Everything works fine and dandy except xplot84driver. This currently means I have to convert every plot file on the command line using pltdev then use Preview to

[ccp4bb] glycosidic bonds for refmac library

Hello everyone, I have a couple of structures which contain oligomeric sugars in different conformations. Is there any general way of defining a glycosidic bond for the refmac library - instead of creating .cif files for every single ligand-structure ? Thank you very much in advance Eike

Re: [ccp4bb] xplot84driver problems

Did you make your plt file on the intel mac? I've noticed that ones I made on ppc give that error on my otherwise functional xplot84driver (in the fink package). I tried byte-swapping with dd but to no avail. I guess this is still the cutting edge of 1984 software? Bill On Thu, 6 Sep 2007

Re: [ccp4bb] xplot84driver problems

The file format is definitely machine byte order dependent. (see $CDOC/plot84.doc) A few years ago I was toying with the idea of making library code deal with swapping if need be... Never did it though William Scott wrote: Did you make your plt file on the intel mac? I've noticed that

Re: [ccp4bb] xplot84driver problems

Hi, Yes, I made the files on the Intel Mac. I've sent one to Charles Ballard for testing. They do also work wih pltdev. I agree about the antediluvial origins of xplot84driver, but for lack of anything better... Derek On Sep 6, 2007, at 17:15, [EMAIL PROTECTED] wrote: Did you make

[ccp4bb] just how bad can phases be and still help

general question - perhaps the fundamental question - for anyone who had weak/poor/bad phases from some source, that were later actually used to solve a structure when combined w/ another source - HOW bad were the worst phases on their own, in terms of resolution, FOM, CC, e-density, (any

Re: [ccp4bb] just how bad can phases be and still help

Hi Bryan: I think the question is hard to answer because the idea of bad phases is not particularly well-understood (at least by me). Good phases give you a nice map. Weak phases give you a map that is weakly interpretable, but often can be improved by solvent flattening, NCS averaging, and so
