Playground Blocks
In the following sections, we will explore two simple yet practical blocks built around the NCBI BLAST software:
Make BLAST Database
This block enables users to construct a local BLAST database from a FASTA file. The source code can be accessed at GitHub. For development purposes, we recommend downloading it as follows:
git clone git@github.com:platforma-open/makeblastdb.git
cd makeblastdb
pnpm install
pnpm -r run build
This block allows you to import or upload a FASTA file containing reference sequences. It then runs the makeblastdb command to create a local database and displays the execution log on the main screen:

BLAST Local Database
This block allows users to run BLAST searches against a local database. The source code is available at GitHub. We recommend downloading it for development use:
git clone git@github.com:platforma-open/blast.git
cd blast
pnpm install
pnpm -r run build
Using this block, you can import or upload a FASTA file containing query sequences. It then executes blastn or blastp software, depending on the database type, and displays the resulting alignments:
