Re: [ccp4bb] Off-topic - Crystallisation in anaerobic glove box
Thanks for all of the responses, there seems to be no real consensus, but I have discovered: 1 There are several small incubators supplied by - Molecular Dimensions, Revsci, Centeo 2 Good air conditioning may negate the need for an incubator. 3 A Glove box may not even be necessary depending on the samples sensitivity to oxygen. Certainly plenty for me to think about before I commit to buying a glove box. Yet again the bulletin board proves to be a great source of information for all things crystallographic!

Re: [ccp4bb] Refinement of Iron-sulphur clusters
Dear Matthew, Robbie Hans and Oliver, Thanks for the advice, it seems that it is simply the geometry definitions in the dictionaries distributed with CCP4 6.4 are different to those calculated from the atomic coordinates. For example, the chiral volume definitions in the for the 4Fe4S cluster are the opposite sign to those in my protein. So swapping the atom names has sorted that, I am still working on the other clusters, but progress is being made. Since I solved the structure by MR using coordinates downloaded from the pdb, I assumed the atom names would agree with the geometry definitions in Refmac (since the search model was also refined with refmac). Have the cif dictionaries been modified/updated recently? thanks again, Steve Dr Stephen Carr Research Complex at Harwell (RCaH) Rutherford Appleton Laboratory Harwell Oxford Didcot Oxon OX11 0FA United Kingdom Email stephen.c...@rc-harwell.ac.uk tel 01235 567717 From: Oliver Smart [osm...@smartsci.uk] Sent: 13 October 2014 12:09 To: ccp4bb Subject: Re: [ccp4bb] Refinement of Iron-sulphur clusters Stephen, Robbie advice is 100% correct. Be careful about the naming of the sulphur atoms (is S1 opposite S4 or next to it). I recall that the distributed CCP4 dictionaries have different atom naming than the PDB chemical components dictionary. If this is the problem is that the naming is different this should result in large restraint violations that should be appear in the REFMAC output (others can tell you where). In general diffraction from Fe S clusters is so strong that the atom positions are pretty much determined from the electron density. But in case it helps I did some work data mining restraints for Fe2S2 and Fe4S4 from CSD structures (this has to be done manually). Please find attached the resulting FES.cif and SF4.cif restraint dictionaries (distributed with BUSTER).

One of the clusters (3fe 4s) seems to behave resonably and the refined electron density looks very nice. The atoms in the others clusters (4Fe4S and 4Fe3S), however, migrate towards the centre of the cluster producing Fo-Fc difference maps with strong negative density at the centre surrounded by blobs of positive density where the atoms should be. I have checkedthe refmac dictionaries and there are entries for each of the clusters, so I shouldn't have to explicitly include a cif file for the clusters as an input right? In fact, when I did try to include a dictionary file for one of the clusters refmac gave a warning message in the log about duplicate monomers dictionaries and it made no difference to the refinement/maps anyway. On checking the refmac log file there is no specific mention that there are hetero-groups in the pdb file and no explicit mention that it is using any dictionaries during the refinement. How can I tell if refmac is reading/using the dictionaries? Also bonds within the clusters are flagged up as outliers and deviating by more than 10 sigma from ideal suggesting that they are not getting read? I realise that something chemically odd could be going on at the centres, but if I omit them from the model and calculate maps very strong density comes back around where the atoms sat before refinement, so I am pretty confident that they are in the right place to start with. Any help with this problem would be greatly appreciated, I'm sure there is something obvious that I am missing but can't see what that is at the moment. It is particularly confusing since one cluster apparently behaves while the others do not.

[ccp4bb] xia2 error
Dear all, I have come across an error when trying to run xia2 (version 0.3.3.1) via the ccp4 gui see below, #CCP4I TERMINATION STATUS 0 Error from script /home/applications/CCP4-6.2.0/ccp4-6.2.0/ccp4i/scripts/xia2.script: no files matched glob pattern *.log #CCP4I TERMINATION TIME 17 Feb 2012 12:49:21 #CCP4I TERMINATION OUTPUT_FILES /home/tfr35668/Diamond_I02_17012011/Steve/process/xia2_21 #CCP4I MESSAGE Task failed The error occurs before the program tries to read any image files and it seems to be complaining about a lack of log files before it has had a chance to write them. Any thoughts as to how to fix this would be greatly appreciated. I am running version 6.2.0 and performed a standard installation. best wishes, Steve Dr Stephen Carr Research Complex at Harwell (RCaH) Rutherford Appleton Laboratory Harwell Oxford Didcot Oxon OX11 0FA United Kingdom Email stephen.c...@rc-harwell.ac.uk tel 01235 567717
[ccp4bb] cTruncate failure after data scaling
Dear CCP4, I have encountered the following error message when scaling a recently collected data set. The program run with command: /home/applications/CCP4-6.1.13/ccp4-6.1.13/bin/ctruncate -hklin /tmp/tfr35668/Diamond270211_21_2_mtz.tmp -hklout /tmp/tfr35668/Diamond270211_21_4_mtz_S-SAD1_P43212.tmp -colin /*/*/\[IMEAN,SIGIMEAN\] -colano /*/*/\[I(+),SIGI(+),I(-),SIGI(-)\] -colout S-SAD1_P43212 has failed with error message CCP4MTZfile - internal error terminate called after throwing an instance of 'clipper::Message_fatal' The data have been integrated in imosflm with no apparent problems and Scala scales the data. The problem seems to be that ctruncate then falls over when trying to output the data (I specified the ctruncate run from within the scala window in the CCP4i gui). Searching for this error message doesn't bring up anything useful so could anyone suggest what might be going wrong?

Dear CCP4BB, I have installed the latest version of the ccp4 suite on a linux box (Centos 5.4) and mostly this has gone according to plan, however, when I try and run imosflm I get the error message cannot execute ccp4iwish:no such file or directory. A quick google search revealed that this was a problem on the pre-release of the OSX version of the suite so i tried the workaround suggested, but with no luck. Any thoughts on how to proceed would be gratefully received.
