Can anyone tell me if the following waring is critical or what is its
meaning when I perform bl2seq?
----------------------------------------------------------------------------

[bl2seq] WARNING: [000.000] Blast: No valid letters to be indexed on context
0
----------------------------------------------------------------------------

thanks in advance!
