# SPARK (wild-type accumulator phenotype): Human-curated and standardized MICs

These data were collated by the authors of:

> Shared Platform for Antibiotic Research and Knowledge: A Collaborative Tool to SPARK Antibiotic Discovery
> ACS Infectious Diseases 2018 4 (11), 1536-1539
> DOI: 10.1021/acsinfecdis.8b00193

We cleaned the original SPARK dataset to subset the most relevant columns, remove empty values, 
give succint column titles, and split by species.

This particular dataset retains only measurements on bacteria with wild-type accumulation phenotypes.

The SMILES strings have been canonicalized, and split into training (70%), validation (15%), and test (15%) sets 
by Murcko scaffold for each species with more than 1000 entries. Additional features like molecular weight and 
topological polar surface area have also been calculated.

## Dataset Details

### Configurations

The config `all` gives the entire cleaned wild-type accumulator dataset. 

Species specific configurations can be accessed:

| configuration            | n_rows |
| ------------------------ | ------ |
| Acinetobacter-baumannii  |   2148 |
| Brucella-abortus         |   9947 |
| Escherichia-coli         |  19660 |
| Francisella-tularensis   |   9672 |
| Klebsiella-pneumoniae    |   3713 |
| Pseudomonas-aeruginosa   |  15454 |
| Staphylococcus-aureus    |   1914 |
| Streptococcus-pneumoniae |   1254 |
| Yersinia-enterocolitica  |   1405 |
| Yersinia-pestis          |  10003 |
