getting .nal files from blast
Hello,
So I am making my own databases from fasta files using Blast version ncbi-blast-2.5.0+.dmg and getting an error that is linking back to by database creation by not having a .nal file created. I am entering in: makeblastdb -in test2.fasta -out MV1SDB_a/MV1SDB_a -parse_seqids -dbtype nucl And getting the following files outputs: MV1SDB_a.nhr MV1SDB_a.nin MV1SDB_a.nog MV1SDB_a.nsd MV1SDB_a.nsi MV1SDB_a.nsq How do I change my coding to recieve a .nal file as one of my outputs. |

This is a near duplicate of your other thread where you have been given advice and help: http://seqanswers.com/forums/showthread.php?t=72083
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). Last edited by maubp; 10-26-2016 at 08:11 AM. Reason: fixed markup |
