nr.00.tar.gz is 'just' a tar archive containing the files.

expand it before use

tar xvfz nr.00.tar.gz

florian.grosmaire : You will need to download and expand ALL nr files for this to work (38 pieces as of today).

ok thanks, I'll do that Last question, I am not sure about the "entry" parameter. Does a text file containing sequences ID could be used ?

Use -entry_batch parameter with an input file with sequence ID.
