Hi Yarrow,
You can use the likes of areaimol to calculate the surface accessible area,
with or without accounting for crystal symmetry:

There are other alternatives, but I hope that helps,

Sorry for the non-CCP4 question. But please help!!
I have to install jre 1.5_22 on my mac to have the COEUS (MIT software
premium). My computer already has java 1.6
How to install the old version. If this old is not on the computer, then the
install commands do not work.
Thanks a lot

I have a buried active site and would like to determine if there is room
for a water molecule in various mutants. Does anyone know of a good
program to calculate this? I have heard of GRID and VOID but have never
used them.
Thanks.

Dear CCP4BBers
we have an opening for an EMBL Interdisciplinary Postdoc (EIPOD)

high-precision diffactrometer on the P14 beamline
at EMBL Hamburg. Beamline P14 will be fully tunable and have a
sub-10-micron focus and is equipped with
Dear Ed -
I agree with you, and I felt a little funny giving that advice, since I
know that Rmerge is rather outdated as a resolution cutoff. What I was
really reacting to was the slope of I versus resolution; if you look at
Qing's Scalepack table, you can see that average I plateaus in the l

Why? I would rather suggest Qing extends resolution to where

- Your space group is almost certainly P31 2 1. Your scaling statistics
results point to this - if your true space group was P31,
then your statistics would be noticeably (even dramatically) worse in
the higher symmetry space group.
I've seen a "dramatic" counter-example to thi
Hi Matt,
You may be right, but how do you distuinguish you between a
crystallographic 2-fold and perfect twinning? A solution that refines to
an Rfree of 55.6% is not exactly a textbook example of a correct
solution. Poor data, low-resolution and twinning/pseudosymmetry can
cause all kinds of artef
Hi Qing -
Just a couple of observations on your story, without a real solution:

What is the model based on (i.e. how much sequence identity you have)?

Seeing Herman's message reminds me that I forgot to send this reply to the BB

Herman makes many of the same points, and a very good additional point that you
want to examine whether the molecular replacement solution in the lower
symmetry space group actually has the higher symmetry.
Dear Quing,
My first suggesting is a no-brainer: try to get better data. At 4.3Å model
building and refinement will remain painful, whatever you try. Getting better
data includes improving your crystals (ligands, additives etc.) and the
cryoconditions. You could also try to collect data on say
