# 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](https://doi.org/10.1093/bib/bbab260)

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](https://depmap.org/portal/download/). We provide GDSC1/GDSC2 pre-processed expression and response data, as well as CTRP response data and depmap's CCLE expression data (18Q2) [here](https://osf.io/c6tfx/).
 
 
User Notes: 

- Reminder that it is best to logtransform the training and test datasets (i.e. log(TPM + 1)) before batch correction ("eb"). That is, use log-transformed expression data when using calcPhenotype.
