From a practical point of view,  a solution for documenting grouped
occupancy refinement should at minimum allow

(a) easy  automatic harvesting from the respective refinement log
files, and 

(b)   equally easy extraction from the PDB/cif format to replicate the same
refinement

(c)not mess up legacy code/format or use undocumented 'features'

How this is best implemented is probably not trivial (except the REMARK
kludge) 

and needs the data base/integrity/validation experts.

Hello,

 

A solution exists also for PDB records:

 

As a consequence of a discussion with George which took place  years ago, I
have taken the liberty to extend the PDB record length of 80 characters  and
use additional characters to specify the group ID and their members list
number and provided an interface to manipulate them.  Thereby the PDB
limitations were extended to adopt the SHELX philosophy of treating combined
groups of any composition.

 

ATOM  1  N   GLY A   1 -31.334 -24.247  23.250  0.54 34.05  1A
N   1   0

ATOM   2477  N   GLY A   1 -29.650 -24.643  23.839  0.46 41.88  1B
N   1   1

 

The records with our the group extension are not members of groups with
partial occupancy. These two records shown are members of group ID 1, the
atom in the first record belongs to group ID 1 members list number 0 and the
second to group ID 1 and members list no 1.  (The members lists begin with
0.)

I agree that it would be excellent to be able to associate alternate
conformations (beyond the individual residue) but when we defined the PDB
format we had an 80-column limitation per atom and so only one column was
allowed for alternate conformations.  In an ASCII world only 36 characters
were available to define alternate conformations.  This is inadequate to
allow for many residues with independent alternate conformations - one
residue with three conformations would use up 3 of the 36 characters.  Thus
there was no way to say that alternate conformation A in one residue is or
is not associated with alternate conformation A in another residue.

Hi James,

I would say that 0.333 (in a scientific context) implies that I am
confident about this number up to the third decimal point, i.e. 0.3325
= x = 0.3334. This gives you an idea of the precision. 1/3 is not a
scientific format, but a mathematical one, unless for some constraint
you know that value is exactly 1/3, then there is no error associated
with it.

Cheers,
Tim

 If mmCIF were a binary floating-point format file, there would be
 more decimal places in the precision of the stored value for the
 unit cell, despite fitting into only 4 bytes instead of the 13
 bytes of text some seem offended to see below.  Would that be
 better?  Or worse?

Re: [ccp4bb] Problem in molecular replacement

2014-07-24 Thread Randy Read
In addition to that good suggestion, with a model at such high sequence 
identity and with reasonable resolution data, it would be a good idea to search 
for smaller models, like a single dimer or even a monomer, because the assembly 
may have changed conformation.  Another possibility you should consider is that 
the space group may not be correct.

Good luck!

There you can download OSX_binaries for Lion and Snow Leopard. The

Not sure why this qualifies as a flame or who you want to flame - seems
reasonable
but needs to be done so that the data items are extracted consistently from

 correlated alternate confs - validation?
 
 
 
 Hello,
 
 
 
 A solution exists also for PDB records:
 
 
 
 As a consequence of a discussion with George which took place years 
 ago, I have taken the liberty to extend the PDB record length of 80 
 characters  and use additional characters to specify the group ID and 
 their members list number and provided an interface to manipulate 
 them.  Thereby the PDB limitations were extended to adopt the SHELX 
 philosophy of treating combined groups of any composition.
 
 
 
 ATOM  1  N   GLY A   1 -31.334 -24.247  23.250  0.54 34.05
 1A N   1   0
 
 ATOM   2477  N   GLY A   1 -29.650 -24.643  23.839  0.46 41.88
 1B N   1   1
 
 
 
 The records with our the group extension are not members of groups 
 with partial occupancy. These two records shown are members of group 
 ID 1, the atom in the first record belongs to group ID 1 members list 
 number 0 and the second to group ID 1 and members list no 1.  (The 
 members lists begin with 0.)

 I agree that it would be excellent to be able to associate alternate 
 conformations (beyond the individual residue) but when we defined the 
 PDB format we had an 80-column limitation per atom and so only one 
 column was allowed for alternate conformations.  In an ASCII world 
 only 36 characters were available to define alternate conformations.  
 This is inadequate to allow for many residues with independent 
 alternate conformations - one residue with three conformations would 
 use up 3 of the 36 characters.
 Thus there was no way to say that alternate conformation A in one 
 residue is or is not associated with alternate conformation A in 
 another residue.

Dear Andreas, 

we had a similar issue with our MicroMax 007, with a primary water/water 
chiller (ATC K3) in between the generator and a secondary inhouse water 
circuit.  

After a year of reliable service the K3 would shut off occasionally and dump 
the 007 with a cooling error. We found that the solution to the issue was to 
place an additional pump directly in front of the K3. The issue being that the 
latter would temporarily shut off unless provided with a constant water 
pressure, which the water circuit wasn't giving apparently.

This has now been running fine. Another solution would be a water-air chiller 
to cool your 007, but in our case that was not an option due to building specs. 

Hope this helps. I'm happy to provide more details if wanted.

I would warn you that the K3 and K9 chillers have internal hoses which cannot 
tollerate water pressure above 125 psi.  We had a hose fail from the building 
chilled loop pressure.  So, be careful adding any pressure with a pump before 
the chiller...and maybe consider one after the chiller to pull the water 
through.

Re: [ccp4bb] rigaku micromax 007 cooling

2014-07-24 Thread Matthew Franklin

Hi Andreas -

My 007HF is cooled by a Haskris R050 chiller which I got from Rigaku.  
This has a refrigeration loop inside it to extract heat from the closed 
water loop that goes to the generator; the extracted heat can then go to 
building chilled water, or even an open loop (city cold water, then down 
the drain) if your building codes allow it.


The advantage of this system is that it can handle unreliable chilled 
water temperature and flow, with allowable source water temperatures as 
high as 85 F.  If your building water is really unreliable, you can even 
get an air-cooled Haskris - although your room A/C has to be able to 
handle the heat load in that case.


Contact me off-list if you want more information.  The system has been 
really reliable for me.


- Matt

Re: [ccp4bb] rigaku micromax 007 cooling

2014-07-24 Thread Ed Hoeffner
Hi

Ours is cooled by a Haskris R250, which is sized for an XStream also. While
our heat exchangers have had a couple of issues, overall the Haskris heat
exchangers have performed quite well. They redesigned ours when they found
out about our building chilled water. I'm not affiliated with and heartily
recommend them.

As for the water itself, I would ***NEVER*** allow building chilled water
into the generator. Our water is extremely dirty and the supply is slightly
below spec, so we have a pump downstream of the heat exchanger. There are
also 2 filters upstream to pull some of the junk out. Lately, startup has
required the use of the pump, which I interpret as buildup in the condenser,
so that's eventually going to need a cleanout. That was what the redesign
was all about.

I imagine ours is an extreme case, but the heat exchanger makes up for a
variety of ills. Rigaku also recommends a DI filter to keep conductivity low
in the water going into the generator, which improves anode lifetime.
Building chilled water will never be able to be as low as desired. Besides,
facilities people can change things and you'd never know until it's too
late...
