There is an updated release of a CIF version of RasMol, version 2.6_CIF(Rev 1), based on Roger Sayle's version 2.6, at: http://www.bernstein-plus-sons.com/software/rasmol/ This is a minor update to version 2.6_CIF which adds allows coloring of small molecule alternate conformers, corrects the handling of nucleic acid residue names, and fixes some problems with bonding. Precompiled versions for SGI (IRIX 5.3 and IRIX 6.4), Windows and Macintosh are available via links on http://www.bernstein-plus-sons.com/software/rasmol/INSTALL.html Complete source and documentation with an updated manual and reference card are available via these web pages. Distribution of additional precompiled binaries would depend on arrangements for access to appropriate systems. If you use the switch "-cif", this version will read a core CIF or mmCIF dataset. Coloring of alternate conformers and multiple NMR models is supported. Fractional coordinates are supported. THIS IS A PRELIMINARY RELEASE INVOLVING EXTENSIVE MODIFICATIONS ***** USE WITH CAUTION ****** Comments and suggestions appreciated. -- Herbert J.
