Dear all,

A couple of people have pointed out problems when installing the ARP/wARP CCP4i GUI over 64-bit fink installations
of CCP4, in Mac OSX 10.6 Snow Leopard. Although I am not confident we understand the problem 100%, it appears
to be genuine, and most likely related to 64-bit versions of bltwish.

With the kind help of Felix Frollow and - you would not have guessed - Bill Scott, it appears that the following workaround is valid:

sudo /bin/bash  {or /bin/tcsh, or /bin/zsh, should not matter}
source /sw/bin/init.csh {or .sh. that the fink setup, you need to do that steo}
ccp4i
{use the gui to uninstall previous versions and install the new one}

Then you can exit, and from a new terminal you can go on using your installation as a normal user.

Note, that this installation problem only affects the GUI, and you can anyway use the scripts
(e.g. auto_tracing.sh) and use for e.g. ligand fitting the functionality of arpnavigator, or use a 32-bit installation.

Best wishes to all -

Dear All,

We are happy to announce the release of ARP/wARP version 7.1.

Please visit http://www.arp-warp.org for details and software download.

The major implementations and improvements are:

• A prototype of the molecular graphics ARP/wARP front-end, allowing the
display of molecules and electron densities.
• A prototype version of the new module for building poly-nucleotides
(DNA or RNA).
• Improved and faster protein chain tracing with higher performance at
lower resolution.
• The loop building as well as helix/strand building are now also
inherent parts of protein model building, resulting in enhanced model
completeness.
• Refinement procedures during automated model building have been
enhanced in the new versions of our preferred refinement engine, REFMAC,
notably including the implementation of 'conditional restraints'.
• Direct use of experimental single-wavelength anomalous diffraction
data (SAD) during model building is now also possible.
• Improved performance of automated ligand building.
• Supported computer platforms are Mac powerpc, Mac Intel and Linux
(including 32 and 64-bit versions and itanium).

Merry Xmas and Happy New Year!

Victor and Tassos on behalf of the ARP/wARP developers' team.
