The tool applies five rules to flag structures likely to degrade before measurement, potentially saving thousands of dollars per design by preventing synthesis of invalid structures. RNAValidate is predictor-agnostic and works with outputs from AlphaFold-3, RiboSphere, and RoseTTAFold-RNA.", "body_md": "A predictor-agnostic linter that checks AI-predicted 3D RNA structures against experimental data (FRET, cryo-EM, SHAPE/DMS probing, designability) — and flags the ones that will hydrolyze before you can measure them.\n\nPredictors and designers (AlphaFold-3, RiboSphere, RoseTTAFold-RNA) are plentiful; an open-source, reproducible layer that *audits* a predicted 3D RNA structure against experimental evidence is not. Validating before synthesis saves thousands of USD per design.\n\nRNAValidate reads the PDB + JSON you produce and applies five rules:\n\n**F1 is a DERIVED rule** (risk R5), proposed by the author and not extracted from a single paper. It needs experimental validation against measured degradation (tube half-life) before promotion to a hard rule. Thresholds (FRET RMSD, cryo-EM CC) are documented chemistry, not tuned to the fixtures. Fixtures use a minimal synthetic hairpin PDB plus example FRET (external-validity, not circular).\n\n```\npip install -e .\nrnvalidate check --in structure.pdb --exp exp.json --format json\n```\n\n*License: AGPL-3.0-or-later (c) 2026 Pedro Sordo Martinez — amurlaniakea@gmail.com*", "url": "https://wpnews.pro/news/rnavalidate-cpu-only-validator-for-ai-predicted-3d-rna-structures", "canonical_source": "https://dev.to/magopredator/rnavalidate-cpu-only-validator-for-ai-predicted-3d-rna-structures-35g0", "published_at": "2026-07-12 23:06:38+00:00", "updated_at": "2026-07-12 23:14:15.739024+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-tools", "developer-tools", "machine-learning", "ai-research"], "entities": ["Pedro Sordo Martinez", "AlphaFold-3", "RiboSphere", "RoseTTAFold-RNA", "RNAValidate"], "alternates": {"html": "https://wpnews.pro/news/rnavalidate-cpu-only-validator-for-ai-predicted-3d-rna-structures", "markdown": "https://wpnews.pro/news/rnavalidate-cpu-only-validator-for-ai-predicted-3d-rna-structures.md", "text": "https://wpnews.pro/news/rnavalidate-cpu-only-validator-for-ai-predicted-3d-rna-structures.txt", "jsonld": "https://wpnews.pro/news/rnavalidate-cpu-only-validator-for-ai-predicted-3d-rna-structures.jsonld"}}
