[EMBOSS] Databases

[Nabeel Ahmed]

I have recently installed EMBOSS-6.4.0 (Ubuntu 11.10).
I am unable to make it work directly with live databases (embl, uniprot) ,
working totally fine with local sequence files.
e.g

% *plotorf  *
Plot potential open reading frames in a nucleotide sequence
Input nucleotide sequence: *embl:x13776*

*Error:* Failed to open filename 'embl'**

Used 'showdb' , displayed table with zero rows.

Is there any configuration, i am missing??

Thanks
Ahmed
