                               pepwindowall 



Function

   Displays protein hydropathy of a set of sequences

Description

   pepwindowall produces a set of superimposed Kyte & Doolittle
   hydropathy plots from an aligned set of protein sequences.

   The result is the same as running pepwindow on a set of proteins with
   aligning gaps and superimposing the plots.

   It is useful for visualising the average hydropathy and its
   variability along the alignment.

Usage

   Here is a sample session with pepwindowall


% pepwindowall globins.msf -gxtitle="Base Number" -gytitle="hydropathy"

Data files

   pepwindow reads the Kyte-Doolittle hydropathy data from the file
   'Enakai.dat'

   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

   The EMBOSS data file 'Enakai.dat' contains :-
