Many new features for version 1.18 of SOLVE:

Resolve version 1.04 (Reciprocal-space solvent flattening and maximum likelihood density modification) is now available (free) for SOLVE users!
SOLVE now has easy scripts for SAD phasing.
SOLVE has even better MAD phasing! SOLVE now re-refines scattering factors using the final heavy atom parameters, improving the final phases. In combination with version 1.04 of resolve, the final maps are greatly improved over version 1.17.
Must faster search for solutions: SOLVE now follows only the very best solution by default, greatly speeding up the search in most cases.
You can start from MR or other input phases.
You can read CCP4 unmerged intensities directly.
You can specify a SOLVETMPDIR where SOLVE will write scratch files.
You can tell SOLVE where some sites are and go on from there easily with ANALYZE_SOLVE and with ADDSOLVE
There is now a SOLVE FAQS page.
You can load the SOLVE manual with a web browser just by typing "solvehelp" on your terminal!

What is SOLVE?	SOLVE is a program that can carry out all the steps of macromolecular structure determination from scaling data to calculation of an electron density map, automatically.
What can SOLVE do?	SOLVE does everything crystallographers do to solve an MIR or MAD structure, but automatically. It scales data, solves Patterson functions, calculates difference Fouriers, looks at a native Fourier to see if there are distinct solvent and protein regions, and can score partial MAD and MIR solutions to build up a complete solution. SOLVE has solved MIR and MAD structures with up to 52 heavy-atom sites. Check out some examples and look at the on-line manual for more info!
How do I get SOLVE?	You can get a license by filling out and faxing us a signed license form. You'll get a free trial license right away. You'll get a permanent license as soon as any licensing fees are received. The forms for academic licenses are on-line. They will take a couple days to process after you turn them in. Commercial and government licenses are available by email. You can download SOLVE from an anonymous ftp site as soon as your license is set. You can upgrade to the current version of SOLVE any time by downloading it in the same way as you download for the first time.
