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 REBASE restriction enzyme data files are stored iin directory 'data/REBASE/*' under the EMBOSS installation directory.
These files must first be set up using the program 'rebaseextract'. Running 'rebaseextract' may be the job of your system manager.
The data files are stored in the REBASE directory of the standard EMBOSS data directory. The names are:
The reported enzyme from any one group of isoschizomers (the prototype) is specified in the REBASE database and the information is held in the data file 'embossre.equ'. You may edit this file to set your own preferred prototype, if you wish.
The format of the file "embossre.equ" is
Enzyme-name Prototype-name
i.e. two columns of enzyme names separated by a space. The first name of the pair of enzymes is the name that is not preferred and the second is the preferred (prototype) name.
Program name | Description |
---|---|
recoder | Remove restriction sites but maintain same translation |
redata | Search REBASE for enzyme name, references, suppliers etc |
remap | Display sequence with restriction sites, translation etc |
restover | Find restriction enzymes producing specific overhang |
restrict | Finds restriction enzyme cleavage sites |
showseq | Display a sequence with features, translation etc |
silent does the opposite to recode. silent finds sites where a restriction enzyme site can be introduced without changing the translation in frame 1 of the sequence. recode finds sites where a restriction enzyme site can be removed without changing the translation in frame 1 of the sequence.
