As of April 24, 2000, there are currently no known bugs in version 2.1. A variety of problems and shortcomings in SnB v2.0 Beta have been corrected. Most of these should not make the critical difference between solution and non-solution. Cases where there will be a critical difference include:

  • Structures in space group F222.
  • Structures having R-centered lattices.

There was a bug in the SCALEPACK input routine that caused intensity values for very large reflections to be read incorrectly. In situations where SCALEPACK files were used and no solutions were found, it is advisable to repeat the calculations. This is also true in all cases where the user wishes to make absolutely certain that none of the smaller bugs precluded successful applications in the past.
