Drug Response Modeling and Biomarker Discovery.

oncoPredict

(Predict Response from Expression Data and Identify Cell line/Clinical Targets and Trends)

Additional details about this package can be found in our publication oncoPredict: an R package for predicting in vivo or cancer patient drug response and biomarkers from cell line screening data

An R package for drug response prediction and drug-gene association prediction. The prepared GDSC and CTRP matrices for the calcPhenotype() are located in the oncoPredict OSF.

• For drug response prediction, use calcPhenotype.
• For pre-clinical biomarker discovery, use GLDS.
• For clinical biomarker discovery, use IDWAS (for CNV or somatic mutation association with drug response) or indicate cc=TRUE (for gene expression association with drug response) in calcPhenotype().
• The link to updated CCLE gene expression data is found at depmap. We provide GDSC1/GDSC2 pre-processed expression and response data, as well as CTRP response data and depmap's CCLE expression data (18Q2) here.
