Function

   Displays aligned sequences, with colouring and boxing

Description

   prettyplot reads in a set of aligned DNA or protein sequences. It
   displays them graphically, with conserved regions highlighted in
   various ways.

Usage

   Here is a sample session with prettyplot


% prettyplot -resbreak=10 -boxcol -consensus -plurality=3 
Displays aligned sequences, with colouring and boxing
Input (aligned) sequence set: globins.msf

Data files

   Prettyplot uses a comparison matrix file to calculate similarity to
   the consensus.

   For protein sequences EBLOSUM62 is used for the substitution matrix.
   For nucleotide sequence, EDNAFULL is used.

   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

Notes
