EMBOSS: embossdata

| embossdata

## Function

Find and retrieve EMBOSS data files

## Description

embossdata searches for a specified data file in all the directories which can hold them and writes the results of the search to screen or (optionally) to file. Optionally, all the files in the searched directories can be displayed. Optionally, it will also copy the file from the EMBOSS standard data directory to the current directory so that you can safely edit and use it.

## Usage

Here is a sample session with embossdata

Display the directories searched for EMBOSS data files:

    % embossdata
    Find and retrieve EMBOSS data files
    Data file name:

    # The following directories can contain EMBOSS data files.
    # They are searched in the following order until the file is found.
    # If the directory does not exist, then this is noted below.
    # '.' is the UNIX name for your current working directory.

    .                                                            Exists
    .embossdata                                                  Does not exist
    /homes/pmr                                                   Exists
    /homes/pmr/.embossdata                                       Does not exist
    /homes/pmr/local/share/EMBOSS/data/                          Exists

Example 2

Display the names of data files in all of the possible data directories: This is run on a small test system and so the results will probably be different when you run this.

    % embossdata -showall
    Find and retrieve EMBOSS data files
    Data file name:

    DIRECTORY: /homes/pmr/local/share/EMBOSS/data/

Example 3

Make a copy of an EMBOSS data file in the current directory:

    % embossdata -fetch Epepcoil.dat
    Find and retrieve EMBOSS data files

    File '/homes/pmr/local/share/EMBOSS/data/Epepcoil.dat' has been copied successfully.

Go to the output files for this example

Example 4

Display the directories which contain a particular EMBOSS data file:

    % embossdata EPAM60
    Find and retrieve EMBOSS data files

    # The following directories can contain EMBOSS data files.
    # They are searched in the following order until the file is found.
    # If the directory does not exist, then this is noted below.
    # '.' is the UNIX name for your current working directory.

    File ./EPAM60                                                     Does not exist

## Data files

No data files are read by this program.

## Notes

Many EMBOSS programs use a data file. The data files are typically kept in a standard directory in the EMBOSS installation (`.../emboss/emboss/data/`). When an EMBOSS programs require a data file, it search for it in the following order of directories:

- The current directory
- `.embossdata` subdirectory in the current directory
- Your home directory
- `.embossdata` subdirectory in your home directory
- The EMBOSS standard data directory

EMBOSS will use the data file it finds first from the above directories. For example, a data file in the current directory is used in preference to a file of the same name in the EMBOSS standard data directory.

It is sometimes necessary to modify a data file to change the behaviour of an EMBOSS program. To do this safely, you should copy the data file from the EMBOSS standard data directory to one of the other directories, such as the current directory or your home directory, before editing it. embossdata helps here by displaying the names of data files in all the directories which could hold them, and copying a data file from the EMBOSS standard data directory to the current directory.

By convention, all EMBOSS data file names start with the character 'E', to distinguish them from other files on your system. For example genetic codes to translate codons to amino acids are held in data files called "EGC.0", "EGC.1", "EGC.2", etc.

### -filename option

Name of data file to search for or copy into the current directory from the EMBOSS standard data directory. The name of the file is not altered when it is fetched. (Any string is accepted).

### -outfile option

Name of file containing the results of searching the data directories. By default this is written to the screen (`stdout`).

### -reject option

The names of sub-directories of the EMBOSS data directory that should be ignored when displaying data directories.

## References

None.

## Warnings

None.

## Diagnostic Error Messages

When copying a file, this program will report if the file has been copied successfully, e.g.:

    "'Epepcoil.dat' has been copied successfully."

## Exit status

It always exits with status 0

## Known bugs

None noted.
