# Program entret

## Function

Reads and writes (returns) flatfile entries

## Description

entret reads a sequence from a database or a file and writes the complete sequence entry to a text file.

The difference between entret and such programs as seqret which also read entries from databases or files and write them to files, is that entret reads and writes the complete sequence entry together with the heading annotation (documentation). entret therefore is very useful for looking at the annotation of sequences from databases, which seqret does not provide.

The other main difference is that when it writes out the sequence entry to a file, the information is treated as text, not sequence, and so options that you would normally use to change the aspects of the sequence to be written will either not be recognised and will cause an error message to be written (e.g. '-osformat') or will be quietly ignored (e.g. '-sbegin', '-send').

If you have defined a database to use GCG indexed databases, then entret will currently only return the annotation and not the sequence. entret will currently only reproduce the original entry, including the sequence, for databases which hold the whole entry in one file (e.g. the original flatfiles or SRS indexed databases).

## Usage

Here is a sample session with entret:

    % entret embl:hsfau
    Reads and writes (returns) flatfile entries
    Output file [hsfau.entret]:
