The code is from a paper entitled "LPI-IBNRA: Long Non-coding RNA-Protein Interaction Prediction Based on Improved Bipartite Network Recommender Algorithm" by Guobo Xie et al. It is written in Matlab.
Lnc_exp.mat stores lncRNA expression profiles information;
PLI .mat stores known protein-lncRNA interaction information;
PPL.mat stores protein-protein interactions.
gaussiansimilarity.m: function of computing Gaussian interaction profile kernel;
main.m: main function;
plot_roc.m: function of calculating the AUC value and ploting ROC cruve;
LPI_IBNRA.m: function of LPI-IBNRA.
