Dear CCP4 Users We would like to announce the joint release of ARP/wARP version 8.0 and CCP4-7.0.065.
ARP/wARP 8.0 provides a considerably improved performance for X-ray crystallographic applications and it is now also capable of interpreting cryo-EM maps at a resolution range 2.0-3.5 Å. Installation and compatibility - Checks for software installation have been enhanced - 32 and 64-bit platforms on OSX and Linux are supported - ARP/wARP is fully compatible with the latest versions of CCP4 and Refmac Protein chain tracing - Protein chain tracing has been made faster and its memory handling has been improved - DipCheck conformational space is introduced for the selection of the chain path - NCS restraints are now default at resolution 1.5 Å or lower - Loop closure can now be provided using a new module Loopy2018 Sequence docking and building - Side chain guess and fit can now be accomplished using a new module SEQQY - Handling of large structures has been enhanced and the maximum number of NCS copies increased to 60 - Both mono- and hetero-multimers can now be handled DNA/RNA building - Nucleotide chain tracing is enhanced with the addition of the second algorithm for phosphate detection - Nucleotide chain tracing now proceeds in an iterative manner, as for protein tracing Identification of crystallographic ligands - Energy estimate for protein-ligand bound state is introduced during identification of crystallographic ligands Solvent building - Building of solvent structure exploits advanced features of Refmac including TLS and local NCS restraints. - Solvent update can optionally be turned off providing a tool for model refinement with Refmac. Building models into cryo-EM maps - Protein and protein-nucleic acid models are built with a minimum user input - Map over-sharpening is handled automatically - Partial models can be completed by sequence-docking and loop building - Models can be refined with a combined real- and reciprocal-space protocol - A very fast secondary structure modelling option can be used separately. -------------------------------- An update No 65 for the CCP4-7.0 series automatically installs ARP/wARP-8.0 on Mac OS X and Linux computers, where ARP/wARP-7.6 has previously been installed as a part of CCP4 installation. (The directory arp_warp_7.6 is _not_ removed , but CCP4 i1 and i2 are switched to version 8.0). In addition, the update No 65 brings the following changes. * refmac5: correction to LINK records * contact: increase MaxSelectedResidues * dials: inclusion of mock module * pointless: update to 1.11.6 * rabdam: update to 1.4.1 * crank2: fixes and improvements * documentation: correction to freerflag documentation In addition, tarballs and bundles for CCP4 Setup Manager consisting of CCP4-7.0.065 and ARP/wARP 8.0 are available from CCP4 Downloads: http://www.ccp4.ac.uk/download Please report any bugs to c...@stfc.ac.uk. Many thanks for using CCP4 and ARP/wARP.
