Bioactivity Dataset Curator & Splitter

Normalize assay units, censoring, and replicates into SAR/QSAR datasets with scaffold, random, or time splits

Hardware and price

Price per run

What a typical run reserves from your wallet: the catalog's expected runtime on each piece of hardware × your plan's per-second rate. Larger inputs reserve more, and you're charged only for the seconds the job actually runs.

In workflows

Chain it with other steps.

Each input and output has a data kind, so the builder only connects steps that fit.

Inputs

  • Table (list)CSV, TSV, JSON

Outputs

  • ArchiveZIP
  • TableCSV
  • MoleculesSMILES
  • TableCSV
  • TableCSV

Run via API

Submit it from your own code.

Use an API key from your account. The estimate uses your plan's rates; submitting reserves that amount from your wallet.

# Estimate the reservation for your plan (payload fields: see the API reference)
curl -X POST https://api.cognichem.com/api/v1/jobs/estimate \
  -H "X-Api-Key: $COGNICHEM_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"job_type": "bioactivity-curate", "resource": "cpu", "payload": {}}'

# Submit (retrying with the same Idempotency-Key never submits twice)
curl -X POST https://api.cognichem.com/api/v1/jobs/submit \
  -H "X-Api-Key: $COGNICHEM_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"job_name": "bioactivity-curate-1", "job_type": "bioactivity-curate", "resource": "cpu", "payload": { ... }}'

  • Fingerprint Similarity & Clustering

    Tanimoto nearest neighbors, Butina clustering, MaxMin diversity, and Scanpy PCA/UMAP/Leiden clustering from molecular fingerprints

  • 3D Shape Similarity

    3D shape and pharmacophore virtual screening: rank libraries against a query conformer with USRCAT and Gaussian shape + color overlay to find scaffold hops

  • Free Wilson Analysis

    Quantify R-group SAR contributions and predict unsynthesized molecules from activity data

  • Matched Molecular Pairs

    Hussain–Rea matched pairs: chemical transforms and activity deltas from a SMILES library

  • Molecule Conversion

    Convert molecule file/data format

  • Molecule Standardizer

    Salt-strip, neutralize, tautomer, and stereo cleanup to parent structures
