   For each pH point it gives the number of bound electrons and the
   charge.

Data files

   iep reads in local data file Epk.dat which contains amino acid pK
   values used to calculate the isoelectric point of the whole protein

   EMBOSS data files are distributed with the application and stored in
   the standard EMBOSS data directory, which is defined by the EMBOSS
   environment variable EMBOSS_DATA.

   To see the available EMBOSS data files, run:

% embossdata -showall

   To fetch one of the data files (for example 'Exxx.dat') into your
   current directory for you to inspect or modify, run:

% embossdata -fetch -file Exxx.dat

   Users can provide their own data files in their own directories.
   Project specific files can be put in the current directory, or for
   tidier directory listings in a subdirectory called ".embossdata".
   Files for all EMBOSS runs can be put in the user's home directory, or
   again in a subdirectory called ".embossdata".

   The directories are searched in the following order:
     * . (your current directory)
     * .embossdata (under your current directory)
     * ~/ (your home directory)
     * ~/.embossdata

   Here is the default Epk.dat file:
# pK values for amino acids
# O=Ornithine J=Hydroxyproline
#
# Amino acid    pK
Amino           8.6
Carboxyl        3.6

C               8.5
D               3.9
