files

   result:  results in a table computed according to
      Condon.Squires1993

   gedop:  parameters to control the program.  The file must contain the
      following parameters, one per line:

      parameterversion: The version number of the program.  This allows the
         user to be warned if an old parameter file is used.

      line 2: width and decimal places of output

      line 3: doubling time in minutes

      line 4: OriC minutes of a locus on the E. coli map

      remaining lines(real, string):
        minutes of locus
        name
      If a line begins with '*' then it is a comment line
      and is skipped.
      If a line begins with 'n' then it is calculated and
      shown but not incuded in the sum calculation.

   output: messages to the user

description

   Compute gene dosage in E. coli based on chromosome location of a
   locus, location of the origin and doubling time.

examples

In Condon.Squires1993
page 1411 is the example:

    "A wildtype E. coli strain with a doubling time of 24.1 min has an
    equivalent of 38 rRNA operons, due to the high replication rate on
    rich media (for calculation, see Materials and methods).

There is only a minor a discrepancy between this result (38) and the
following (36).

Example gedop from the Condon.Squires1993:
