I want Blast old

Question

[betoven966]

Does anyone have the executable of the old blast? (windows) (so I need to execute blastall), I really need it, so if you got it, please send it to me.

Thank you.

As a.zielezinski said, the Blast legacy is still available for download:

ftp://ftp.ncbi.nlm.nih.gov/blast/executables/legacy.NOTSUPPORTED/2.2.26/

Besides, the Blast+ suite includes a perl script to convert legacy commands into blast+ commands - the output format may be different, though.

Having this in mind, I removed your email address from the post.

Is there a pressing need to use old blast? If a package is dependent on old blast that package may be too old at this point and newer alternatives may be available.

You can download executables of old BLAST (in all versions) from the NCBI ftp server: ftp://ftp.ncbi.nlm.nih.gov/blast//executables/legacy.NOTSUPPORTED/2.2.26/blast-2.2.26-x64-win64.exe.
