Setting 1: macau_GDSC.py

Setting 2: macau_GDSC_pred_new_drug.py

Setting 3: macau_GDSC_transduction.py

Setting 4: macau_GDSC_pred_new_drug_new_cell.py

You may need a certain environment to submit your job (depending on the cluster): cluster_script_GDSC.sh

Step 1: use macau_GDSC_pred_new_drug_new_cell.py (for one tissue) or macau_GDSC_interaction_tissue_QC.py (for all tissues) to check the quality of the features. Make sure the performance is greater than 0.3.

Step 2: Generate the interaction matrix using macau_GDSC_interaction_transduction.py (for one tissue) or macau_GDSC_interaction_tissue.py (for all tissues)

Step 3: use macau_GDSC_interaction_tissue_PERMUTATION.py to do random permutation of the cell lines side features. This gives p-value for each data point of the interaction matrix.

Analysis feature interaction result: GDSC_interaction_analysis_Tissue.Rmd

Scatter plot of the result using: Scatter_plots.Rmd

In folder target_progeny11: interaction matrices for 16 GDSC tissues. Since drug target is binary, make sure to ONLY CONSIDER proteins targeted by at least 2 differents drugs.

In folder target_progeny11_PERMUTATION: one file about the counts generated by the permutation in order to compute the p-value ; one file for the p-value matrix ; one file for the adjusted p-values (Benjamini, Hochberg, and Yekutieli).
