SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enable automated prediction and scoring of protein structures from amino acid sequences or FASTA inputs to support model selection, downstream structural analysis, and reproducible pipeline integration.

Core Features & Use Cases

  • Sequence and FASTA Input: Accepts comma-separated sequences or a FASTA file to generate predictions in sequence or fasta modes.
  • Per-Model Scoring Summaries: Produces per-model summaries including model index, CIF path, per-model scores, and an aggregated best_model selection.
  • Operational Controls: Supports sample count, dry-run mode for input preparation without inference, and an info mode for metadata inspection.
  • Quality & Download Guidance: Includes confidence checkpoints (pLDDT, pTM, ipTM), a strict output-download policy using server_file_to_base64, and a recommended preprocessing step for PDB inputs.
  • Use Case Example: Run a five-sample dry-run prediction from a short membrane peptide sequence to inspect input.fasta and verify scoring summaries before full inference.

Quick Start

Use molclaw-chai1-predict to run a dry-run Chai-1 prediction on a provided sequence, generate input.fasta, and return per-model scoring summaries.

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

FAQPage Schema
How do I predict protein structure from a FASTA file and get model scores?

To predict protein structure from a FASTA file, submit your amino acid sequences to generate predictions. You receive per-model scoring summaries, including CIF paths and aggregated best_model selections, for downstream analysis.

What quality metrics are reported for Chai-1 protein structure predictions?

Chai-1 protein structure predictions report pLDDT, pTM, and ipTM confidence metrics. These quality checkpoints enable automated verification and help you select the best model from the generated CIF outputs.

Can I run a dry-run preparation for protein structure prediction without inference?

Yes, you can run a dry-run preparation for protein structure prediction without inference. Dry-run mode inspects and prepares input FASTA files while verifying scoring summaries before committing to full inference.

Does Chai-1 support small-multimer inference workflows?

Chai-1 supports single-chain and small-multimer inference workflows. It accepts comma-separated sequences or FASTA files to generate ranked models and CIF outputs suitable for downstream structural analysis.

How do I download predicted protein structure CIF files?

To download predicted protein structure CIF files, use the strict server_file_to_base64 output policy. This automated download and verification mechanism ensures secure retrieval of your generated models and confidence checkpoints.
