Genome-wide precomputed Pythia predictions for CRISPR-Cas9 3′-tagging — Xenopus tropicalis

Pythia is a tool for designing CRISPR-Cas9 knock-in strategies for endogenous C-terminal protein tagging, which ranks candidate sgRNA/repair-template combinations based on predicted editing outcomes. This dataset contains precomputed Pythia predictions across all annotated protein-coding genes in the Xenopus tropicalis genome, allowing users to query tagging strategies for any gene of interest without re-running the full prediction pipeline locally. Companion datasets are available on Zenodo for Homo sapiens (exonic and intronic) and Mus musculus.
