install local blast

[shuang]

I tried to install local blast on my Linux machine. However, I don't see blastn, nor blastx, not blastp. Why??

commands:

>wget ftp://ftp.ncbi.nih.gov/blast/executa...4-linux.tar.gz

>tar zxvf blast-2.2.25-x64-linux.tar.gz

up to this step, under the directory of blast-2.2.25/bin/, I see those files below

I guess you are missing something.. the above 'fastacmd' and 'formatdb' are from older version of blast. 2.2.25 version is blast+ and you should see 'blastdbcmd' and 'makeblastdb' for fastacmd and formatdb. and you will find blastn and blastp under bin only. Try to install in a new location.

You downloaded from the older format C toolkit BLAST. To get the newer, C++ toolkit BLAST+ suite you should use this URL:

ftp.ncbi.nih.gov/blast/executables/blast+/LATEST/ncbi-blast-2.2.25+-x64-linux.tar.gz

(I wrapped it in CODE tags so the board software would not try to automagically create a link. Copy this link and paste in another window if you want to download.)

just run blastall you'll see all the options, these are the old blast programs, now it's called blast+ suit, as mentioned above.

Hi,

When downloading databases for local blast, I realized NCBI does not hold uniprot database in their site. Is it possible to download uniprot from uniprot.org and use it in blastx? Do I have to format it somehow or does blast recognize it as it is?

Thanks for your help

Dave

Dave,

You can download the uniprot fasta sequences from: http://www.uniprot.org/downloads

You will need to format and create blast indexes before you can use uniprot to blast against. You can find the help manual for blast here: http://www.ncbi.nlm.nih.gov/books/NBK52636/
