SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

BLAST-based sequence similarity is essential for identifying homology and functional clues; this skill provides an integrated, containerized BLAST workflow to run local or remote searches from BioClaw.

Core Features & Use Cases

  • Local and remote BLAST options: run blastn, blastp, blastx, and tblastn against nucleotide and protein databases, using either user-provided sequences or remote NCBI services.
  • Result interpretation and presentation: formats top hits with identities, e-values, and brief annotations; supports downstream analysis like multiple sequence alignment and phylogeny (as follow-ups).

Quick Start

Provide a DNA or protein sequence and specify whether you want nucleotide or protein BLAST.

FAQPage Schema
How do I run a BLAST search to find sequence homology for a DNA or protein query?

To run a BLAST search, provide a DNA or protein sequence and specify the desired program type, such as blastn or blastp. The tool identifies sequence similarity by querying local or remote NCBI databases and returns top hits with identity and e-value information.

Can I use blastn, blastp, blastx, and tblastn against the NCBI nucleotide and protein databases?

Yes, you can use blastn, blastp, blastx, and tblastn against NCBI nucleotide and protein databases. The tool supports both local database queries inside the container and remote NCBI BLAST searches for identifying sequence homology.

What is the best way to get e-value and identity information for my BLAST sequence search results?

The best way to get e-value and identity information is to run your sequence search through this integrated workflow. It formats the top hits with identities, e-values, and brief annotations, providing the essential metrics needed to evaluate sequence similarity.

Does BLAST sequence search support downstream analyses like multiple sequence alignment and phylogeny?

Yes, BLAST sequence search supports downstream analyses such as multiple sequence alignment and phylogeny. After identifying sequence similarity and retrieving top hits, you can proceed with these follow-up analyses to further evaluate evolutionary relationships.

Why use a containerized BLAST workflow instead of standard sequence similarity searches?

A containerized BLAST workflow provides an integrated environment to run local or remote sequence similarity searches without manual database setup. It standardizes the process of querying nucleotide and protein sequences, ensuring consistent results for homology identification.

Do I need to prepare local nucleotide or protein databases before running BLAST?

You do not need to prepare local databases before running BLAST. The tool supports remote NCBI BLAST searches against nucleotide and protein databases by default, while also offering the option to query user-provided local databases within the container.
