Blast 2.2.31+ "makeblastdb": where are my databases?

Question

[kjojess]

I'm trying to figure out how to create a local BLAST database from a fasta file with 2000+ sequences. I thought I had it all figured out, but even though the command window says that a database with the correct # of sequences was created, I cannot find my database anywhere on my computer. I feel like I'm going crazy, but it's probably just that I'm not correctly defining the file path where I'd like the database saved? Or am I not actually creating a database? I'm a newby so any advice would be great!

Here's what I've been doing:

C:\Program Files\NCBI\blast-2.2.31+>makeblastdb -in 30B_R1good_phred16Scontigs.f
as -dbtype nucl -out GoodPhred16Scontigs

And here's what I get as an output from the above script:

Building a new DB, current time: 07/06/2015 15:15:40
New DB name:   C:\Program Files\NCBI\blast-2.2.31+\GoodPhred16Scontigs
New DB title:  30B_R1good_phred16Scontigs.fas
Sequence type: Nucleotide
Keep Linkouts: T
Keep MBits: T
Maximum file size: 1000000000B
Adding sequences from FASTA; added 2232 sequences in 0.504367 seconds.

But there's not actually any type of file created that I can see/find...I'm so confused! Thanks for your help!

did you perform a search for the file name on the entire system? check the C:\ and the C:\Program Files\NCBI\blast-2.2.31+ directories specifically

[kjojess]

I've looked everywhere I can think of, but I will check again, thanks!

try running makeblastdb again but this time specify a full path for the output directory

Hello Everyone,

Greetings of the day, I am also facing the problem in windows10, makeblastdb command added the sequences to make database but the output of alias files are not available in bin folder of NCBI/blast. I request you to all please provide me help to get my databases in bin folder.

It must be in C:\Program Files\NCBI\blast-2.2.31+\GoodPhred16Scontigs

You have to find three new fies starting with the name you selected

[kjojess]

That's where I think the files would be as well, but they're nowhere to be found. I'll keep looking though, thanks!

[kjojess]

The problem was the permissions settings in the directory, thanks for your input!

[sturne29]

How'd you change the permissions settings?

C:\Program Files\NCBI\blast-2.2.31+>makeblastdb -in <path> -dbtype nucl -out <path>

than you will get new generated files

[kjojess]

This is the script and output when I try to define my file path as you suggested:

​C:\Program Files\NCBI\blast-2.2.31+>makeblastdb -in \C:\Program Files\NCBI\blast
-2.2.31+\30B_R1good_phred16Scontigs.fas -dbtype nucl -out \C:\Program Files\NCBI
\blast-2.2.31+\goodphred

DESCRIPTION
   Application to create BLAST databases, version 2.2.31+

Use '-help' to print detailed descriptions of command line arguments
========================================================================

Error: Too many positional arguments (1), the offending value: Files\NCBI\blast-
2.2.31+\30B_R1good_phred16Scontigs.fas

It doesn't like the 'space' in the file path between "Program" and "Files" in "Program Files" but I don't know how to fix it. I must be calling it incorrectly.

The problem might also be with the permissions settings on my directory, trying to change those now...

[kjojess]

It was a problem with the permissions! Finally got the db files to write. Thanks so much for your help!

I have the exactly same problem with you. Could you let me know how you have solved the problem in detail? Thanks in advance.
