NAME
     Sstruc - define trosions and secondary structure for a
     protein

SYNOPSIS
     sstruc -options file

DESCRIPTION
     Sstruc is a program to read in a Brookhaven format file and
     to calculate torsions and seocondary structure assignments.
     It was originally written by David Smith as a replacment for
     the DSSP program of Kabsch and Sander. It is recommended
     that you preprocess files with pdb2atm before use.

     There are two options

     -f   This option tells the program to process the mainchain
          and sidechain data.  This results in a much more
          voluminous output

     -s   Just give data for the mainchain data. This includes
          all the data necessary to run joy.

     The -s and -f options are thus mutually exclusive.

     For further documentation see the SSTRUC manual written by
     David Smith.
