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:
The EMBOSS data file 'Enakai.dat' contains :-
D Hydropathy index (Kyte-Doolittle, 1982)

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 pepwindow, 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.
