I thought to share this tool, in case you need it. The tool automatically downloads ALL NCBI blast databases from NCBI ftp server. The program does not require Perl, Blast or other additional 3rd party programs/tools. It is a stand alone program (about 2-3MB).
This program will be part of a larger package that allows the biologist to automatically install Blast, download databases (and keep them up to date), build its own databases, do advanced data mining, etc. All these functions will be available via GUI.
This tool addresses mostly to biologists and less to bioinformaticians (they already know how to do all this cool stuff from a Linux console; right guys?)
An update was released today 30 March 2015.
PS: Thanks for up votes.
