This is a near duplicate of your other thread where you have been given advice and help:

The .nal file is a plain text file describing how to treat a set of BLAST nucleotide database "chunks" as a single database. When making a database from a single FASTA file this won't happen (unless your FASTA file has an enormous number of sequences).
