Input file format

   pepwindowall reads aligned protein sequence.

   The input is a standard EMBOSS sequence query (also known as a 'USA').

   Major sequence database sources defined as standard in EMBOSS
   installations include srs:embl, srs:uniprot and ensembl

   Data can also be read from sequence output in any supported format
   written by an EMBOSS or third-party application.

   The input format can be specified by using the command-line qualifier
   -sformat xxx, where 'xxx' is replaced by the name of the required
   format. The available format names are: gff (gff3), gff2, embl (em),
   genbank (gb, refseq), ddbj, refseqp, pir (nbrf), swissprot (swiss, sw),
   dasgff and debug.

   See: http://emboss.sf.net/docs/themes/SequenceFormats.html for further
   information on sequence formats.

Output file format

   The output is to the specified graphics device.

   The results can be output in one of several formats by using the
   command-line qualifier -graph xxx, where 'xxx' is replaced by the name
   of the required device. Support depends on the availability of
   third-party software packages.

   The device names that output to a file are: ps (postscript), cps
   (colourps), png, gif, pdf, svg, hpgl, hp7470, hp7580, das, data.

   The other available device names are: meta, x11 (xwindows), tek
   (tek4107t), tekt (tektronix), xterm, text.

   Output can be turned off by specifying none (null).

   See: http://emboss.sf.net/docs/themes/GraphicsDevices.html for further
   information on supported devices.

Data files

   pepwindowall 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 :-

Notes

   In calculating hydropathy, pepwindowall can use any of the amino acid
   parameters from the database of "Nakai et al." which are now included
   in the database AAINDEX. Before running pepwindowall, you must first
   extract the required data files from AAINDEX (see "Data Files"
   section).

   The result of running pepwindowall 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
   an alignment.
