Introduction

Here we describe the protocol used for performing CYANA (Ref. 1,2) structure calculations in each cycle of AutoStructure (Ref. 3).

Protocol

The control file governs the options used in the execution of the AutoStructure run.  It is recommended that the user sets these options in the control file using the AutoStructure GUI.  The options are found in the Command Section (Figure 1).  Select the CYANA-2.1 button.   The calculations are run over a cluster by a shell script called CreateProc.  Typically, we compute 100 structures per cycle (i.e., 4 structures in 25 nodes), and keep the best 20 structures (lowest target function) for input into the next round of NOESYASSIGN.  A queue system (i.e., PBS) is chosen for running over the cluster.  Additional files in CYANA format can be added to the structure calculation in this page, including dihedral angle constraints (.aco), hydrogen bond constraints and manual upper (.upl) and lower (.lol) distance constraints.

Here is an example AutoStructure control file for a CYANA run.

Starting a Calculation

The AutoStructure run is best initiated from the command line in order to perform the structure calculations in parallel.  For example:

/farm/software/AutoStructure/AutoStructure-2.2.1/bin/autostructure -c controlfile_CYANArun -o testCYANArun.out -v
