Introduction

In this section we describe how to analyze AutoStructure results using the graphical user interface (GUI).

Methods

The results of each AutoStructure cycle are nicely collected in directories within the parent output directory specified by the user in the structure calculation command

(see Figure 1). 


Here is a description of the files collected in the output directory:

  • CYCLEs: 
    • CYCLE1-0:  initial fold analysis results
    • CYCLE*-0:  iterative fold analysis
    • others:  validation cycles
  • filename_NA.ovw:  general report on the AuotStructure calculation, including M-scores and global referencing for each NOESY peak list, and the final statistics for each cycle in the run.
  • filename_NA.sec:  secondary structure analysis.
  • filename_NA.exm: complete secondary initial fold analysis report.
  • filename_NA.unassign: list of unsassigned peaks during each cycle of the run.
  • filename_NA.note: report on the preprocessing of the input files and errors.
  • filename_NA.QM:  summary of M scores.  It provides guidance for chemical shift assignment and peak picking.
  • filename_NA.log:  log file for the run.
  • peaklist.noise: list of peaks excluded from NOESY analysis because they do not match any chemical shift assignments (within given tolerances).
  • peaklist.match:  matching results for all peaks in the NOESY list.


One can access the entire output directory using the AutoStructrue GUI, under the AutoStructure pull-down menu -> Open AS OuputDir.
