SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

MolClaw users who need to identify homologous sequences or annotate unknown sequences can run BLAST searches efficiently inside the container without external tooling.

Core Features & Use Cases

  • Local and remote BLAST execution: run blastn, blastp, tblastn against local or remote databases.
  • Flexible input types: supports nucleotide and protein queries with appropriate databases.
  • Use Case: identify an unknown sequence by comparing it to reference databases and retrieve top hits with relevant annotations.

Quick Start

Provide a sequence and select the program and database to execute a BLAST search inside MolClaw and receive the top hits.

Frequently Asked Questions about blast-search

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run a BLAST search to identify homologous sequences?▼

You can run a BLAST search by providing a nucleotide or protein query sequence, selecting the appropriate program (blastn, blastp, or tblastn), and choosing a database to retrieve top homologous hits with annotations.

What is the difference between blastn, blastp, and tblastn for sequence identification?▼

Blastn searches nucleotide queries against nucleotide databases, blastp matches protein queries to protein databases, and tblastn compares protein queries against translated nucleotide databases for identifying homologous sequences.

Can I perform local and remote BLAST searches inside MolClaw?▼

Yes, you can execute BLAST analyses against both local and remote databases directly inside MolClaw without needing external tooling, retrieving top hits in a clear, parseable format for sequence identification.

How do I annotate unknown sequences using BLAST homology discovery?▼

You can annotate unknown sequences by running a BLAST search against reference databases to identify homologous matches, retrieving top hits with relevant annotations for functional annotation and sequence identification.

Does this BLAST tool support both nucleotide and protein query inputs?▼

Yes, this BLAST tool supports flexible input types, accepting both nucleotide and protein queries and matching them with appropriate databases based on the selected BLAST program for homology discovery.
