[EMBOSS] sequence retrieval

the database section of the adminguide
describes all the emboss database indexing methods.
There is also a specific chapter on fasta files
which describes the different forms of fasta files. It is important to 
specify the correct type corresponding to the structure of the sequence 
header line.
And also use full path names for the "Database directory" because relative 
path names like "." can cause problems on some systems.

If you still get trouble, send me the section you have in .embossrc, so I 
can have a look at it.
Hope this helps,
