I downloaded human chromosome from UCSC and tried to make a "blastable" database. Each chromosomes was saved separately, something like chr1.fa, chr2.fa etc. I would like to make one "BIG" and "blastable" database file named as "humna38.fa.
I wrote a command like "makeblastdb -in ~/Database/Chr38/*.fa -dbtype nucl -out human38.fa", but gave me error "Too many positional arguments (1), the offending value: chr10.fa"
What is wrong and fix?
