Use DepInfeR package to infer sample-specific protein dependencies from drug-protein profiling and ex-vivo drug response data
Installation | Introduction | Data input | Pre-processing the drug-protein dataset | Preparation of the drug response matrix | Prepare drug response matrix using z-scores | Assessment of missing values | Subset for cell lines with less than 24 missing values (based on assessment above) | MissForest imputation | Calculate column-wise z-score | Combine the feature and response matrix for the regression model | Multivariate model for protein dependence prediction | Multi-target LASSO model | Examples of how to interpret and perform downstream analyses on the inferred protein dependence matrix | Heatmap of protein dependence coefficients | Differential dependence on proteins associated with cancer types and genotypes | Visualize protein associations with cancer type | Visualize P-values of significant associations between protein dependence and mutational background | Boxplot visualization for the difference of target importance values | Session info
