This tool allows the users to submit log2-CPM values of mRNA and predict the the TNBC status i.e. lymph node metastatic or non-metastatic employing log2-CPM data of signature mRNAs, resulting from analysis of mRNA-seq data of triple negative breast cancer patients. This method requires log2-CPM values of 5 TNBC biomarker genes in each patient to predict patients's status. The first column is mRNA and in second column expression of corresponding mRNA in terms of log2-CPM value in a particular number of patients.
