SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill automates the generation of peptide and peptide-like molecules to accelerate library design, scaffold exploration, and variant creation without manual SMILES editing.

Core Features & Use Cases

  • Template-based generation: Create peptides from predefined structural templates with controlled masked positions to explore scaffold diversity.
  • Sequence-based variant generation: Produce analogs by modifying a user-provided peptide sequence and receive output SMILES for downstream processing.
  • Information queries and guidance: Inspect available templates and supported amino acids, choose filter presets and MW constraints, and verify actual generation counts with retry guidance for insufficient outputs.
  • Use Case: Generate a focused set of tetrapeptide variants for virtual screening by selecting a template, sampling parameters, and MW bounds.

Quick Start

Generate 50 tetrapeptide variants using the tetrapeptide_mask_middle template with default filters and an MW range of 400 to 800.

FAQPage Schema
How do I generate peptide SMILES for virtual screening without manual editing?

Generate peptide SMILES for virtual screening by selecting a structural template, defining sampling counts, and applying MW constraints. The Skill outputs SMILES lists and saved files for downstream processing, automating library design.

What peptide templates and amino acids are available for molecular variant generation?

Available peptide templates and supported amino acids for molecular variant generation can be inspected through information queries. This allows you to verify template structures and amino acid support before selecting parameters.

How do I create tetrapeptide variants from a specific sequence?

Create tetrapeptide variants from a specific sequence using sequence-based variant generation. Provide your peptide sequence, set sampling parameters and MW bounds, and receive output SMILES for downstream optimization.

Can I apply molecular weight filters when sampling peptide libraries?

You can apply molecular weight filters when sampling peptide libraries by setting MW constraints and filter presets. This ensures generated peptide variants fall within your desired mass range.

What should I do if generated peptide variant counts are insufficient?

If generated peptide variant counts are insufficient, verify actual generation counts and use retry guidance. Adjust sampling parameters, MW constraints, or template selection to increase output diversity.

Does this peptide sampling approach work for scaffold exploration and library design?

This peptide sampling approach works for scaffold exploration and library design by using template-based generation with controlled masked positions. It creates diverse peptide and peptide-like molecular variants efficiently.
