GRcalculator: an online tool for calculating and mining drug response data

GRcalculator is a Shiny application (http://www.grcalculator.org) developed to accompany the Nature paper Growth rate inhibition metrics correct for confounders in measuring sensitivity to cancer drugs by Hafner et al. (2016).

For a brief overview of the GRcalculator and the importance of the newly developed GR metrics methodology (Hafner et al. 2016), see this poster: https://figshare.com/articles/GRcalculator_an_online_tool_for_calculating_and_mining_drug_response_data/4244408

The GRcalculator tool (http://www.grcalculator.org) is implemented in the form of three integrated Shiny applications (grcalculator, grbrowser and grtutorial).

grtutorial (https://github.com/uc-bd2k/grtutorial)

The grtutorial Shiny application (“About GR Metrics” link in the toolbar) provides background information about the advantages of the GR metrics over traditional metrics for quantifying dose-response assays as well as descriptions of the GRcalculator tools.

grbrowser (https://github.com/uc-bd2k/grbrowser)

The grbrowser Shiny application (“LINCS Dose-Response Datasets” section in the toolbar) facilitates interactive browsing and mining of drug response data generated by the LINCS project.

GRmetrics R package (https://github.com/uc-bd2k/GRmetrics)

This package re-creates the online calculation and visualization tools available at http://www.grcalculator.org/grcalculator/.
