Re: [ccp4bb] Off-topic - Crystallisation in anaerobic glove box

2015-03-11 Thread Stephen Carr
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!

Best wishes,

Subject: [ccp4bb] Off-topic - Crystallisation in anaerobic glove box

Dear CCP4BBer's

Apologies for the off-topic post, but the CCP4BB seems to be the best place to 
ask about crystallisation.

I am looking to set up crystallisation in an anaerobic glove box and wondered 
how other people did this, specifically the crystallisation stage.  My initial 
thoughts were to place a small crystallisation incubator inside the box, 
however the smallest I have come across so far (~27L) is still rather large.  
Has anyone come across smaller incubators?  Alternatively are incubators even 
neccessary if the glove box is placed in a room with good air conditioning and 
stable temperature control?

Any recommendations would be very helpful.

Thanks in advance,

Re: [ccp4bb] Refinement of Iron-sulphur clusters

2014-10-13 Thread Stephen Carr
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,

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).

Good luck,

Oliver

 Dear Stephen,

 The dictionary is very specific about atom names. If you have them swapped
 (as many PDB entries do). The angle and chiral volume restraints will
wreck
 your cluster. You also need to make sure to provide LINK records to attach
 the cluster to the surrounding cysteines.

 Onderwerp: [ccp4bb] Refinement of Iron-sulphur clusters

 Dear CCP4 BBers,

 I am currently refining a model of a protein containing three iron sulphur
 clusters using Refmac (v5.8.0078) and am getting some unusual results.
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.  I could, of course, try phenix or buster, but I
 would like to get to the bottom of the problem with refmac if possible.

 Thanks very much in advance,

 Steve

Thanks for the help, the old version of truncate did the trick.  Interestingly 
running the old version of truncate in either of the data reduction pipelines 
(with aimless or scala) produced mtz files containing no F's but the stand 
alone version produced an mtz with all the f's prsent.

ctruncate and truncate and also automatically as part of the scaling/merging 
pipelines.  The data were processed with imosflm, scaled with aimless with 
neither flagging any errors with the data.  I am running CCP4 6.4.0 on a linux 
box (Centos 6) and have installed the latest updates. Any suggestions as to 
what the fault might be and how to get around it would be greatly appreciated.

best wishes,

Re: [ccp4bb] Phaser Fatal runtime error.

2012-06-28 Thread Stephen Carr
Dear all,

Thanks for the many of responses, the data from Crysalis is scaled, but 
unmerged so needed to be fed through scala/truncate before running Phaser.  
Phaser is now running with no problems and I am looking at some nice maps.

Bestr wishes and thanks again for your help,

Steve

We have an in-house Agilent (Oxford) system and routinely use data with CCP4. 
You will need to run sortmtz, scala (w/constant scale), and truncate to prep 
the data properly. This can be done via batch file or GUI.You may also have to 
reset/reassign the space group for some space groups due to an apparent bug in 
the CrysalisPro MTZ conversion routine. You can find details at 
capsicum.colgate.edu/chwikihttp://capsicum.colgate.edu/chwiki in our 
crystallography pages.

Dear CCP4bb

I have collected a data-set using the supernova x-ray generator from Agilent 
and taken the mtz file generated by the data processing software in crysalis 
pro forward for structure solution.  The data collection was straight forward 
and the software seemingly processed the data successfully - space-group P2221, 
overall Rmerge 9%, I/sigmaI 11, redundancy 4.5 etc.  Truncate converted the 
intensities to structure factors with no problems, but when I tried to use the 
data for molecular replacement with Phaser it produced the following error:

FATAL RUNTIME ERROR: Reflections are not a unique set by symmetry

I'm not sure how to proceed from here as other programs in the suite do not 
seem to detect this problem.  Also when this error has been mentioned in the 
past on the bb it was with a data set collected on a Bruker home source and the 
data processed with Denzo/scalepack, and the suggested solution was to use the 
Bruker software to process the data.

I am currently attempting to reprocess the data with mosflm, but that is likely 
to be the subject of another post!

Any suggestions will be gratefully received.

Best wishes,

Steve

[ccp4bb] xia2 error

2012-02-17 Thread Stephen Carr
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

[ccp4bb] cTruncate failure after data scaling

2011-03-29 Thread Stephen Carr
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?

Thanks very much,

Steve

[ccp4bb] Problems launching imosflm from ccp4i

2010-03-05 Thread Stephen Carr Please Unsubscribe stephen.c...@diamond.ac.uk As This Address Is No Longer Active
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.

Best regards,

Steve
