In Vitro Toxicokinetic Data Processing and Analysis Pipeline

A set of tools for processing and analyzing in vitro toxicokinetic measurements in a standardized and reproducible pipeline. The package was developed to perform frequentist and Bayesian estimation on a variety of in vitro toxicokinetic measurements including -- but not limited to -- chemical fraction unbound in the presence of plasma (f_up), intrinsic hepatic clearance (Clint, uL/min/million hepatocytes), and membrane permeability for oral absorption (Caco2). The methods provided by the package were described in Wambaugh et al. (2019) <doi:10.1093/toxsci/kfz205>.

README

# Kreutz-Clint file descriptions 

Descriptions of files found within invitroTKstats/inst/extdata/Kreutz-Clint and working/KreutzPFAS. 

The files tracked with the package are contained within this sub-directory, "inst/extdata/Kreutz-Clint", and are only a subset of all the raw data files found within the "working/KreutzPFAS" sub-directory (separate GitHub repository -- see below). We only track a subset of the raw data files due to size constraints. 

The unprocessed data files \insertCite{kreutz2023category}{invitroTKstats} are used within the "Data Guide Creation and Level-0 Data Compilation" vignette to demonstrate the initial steps of the pipelining process (raw data through L0 compilation); they are required to demonstrate how to extract relevant data from the **raw** data files to calculate point estimates of the intrinsic hepatic clearance (Cl~int~). 

### Unprocessed data 

The raw data files containing experimental mass spectrometry measurement data of intrinsic hepatic clearance (Cl~int~) for cryopreserved pooled human hepatocytes. Chemicals were per- and polyfluoroalkyl substance (PFAS) samples. The experiments were led by Dr.s Anna Kreutz and Barbara Wetmore.

**CAUTION: We do not anticipate any changes in the unprocessed data files. If there are any new updates to these files, you must include a note log containing the date and explanation of changes at the end of this README.**
