#This is a sample file distributed with Galaxy that is used to define a
#list of protein BLAST databases, using two columns tab separated:
#
#<database caption>     <path to base name>
#
#For example:
#
#NCBI NR (non redundant)      /data/blastdb/nr
#
#where /data/blastdb/nr.* are the files making up the NR database.
#
#See also the blastdb.loc file which is for any nucleotide databases.
