K2 Submit a Job

K2SA is a protein structure alignment program based on K2. K2SA uses the same basic strategy as K2 but is about 100 times faster. This speed up is the result of

  • A fast simulated annealing technique that replaces the genetic algorithm.
  • Tighter code.
K2SA alignments should be as good as K2 alignments (or even better!). If you'd like, you can still run the old version of K2.

PLEASE NOTE: Be sure to use the 'Browse' buttons to locate the PDB files on your computer's hard drive. PDB codes alone will not work - you must have the appropriate files already on your computer to submit to the server.
