# CAEN
This package provides a feature selection method for single-cell RNA-seq data. It encodes the category number and calculate the spearman 
correlation coefficient between gene and category number. 

# Introduction
With the development of high-throughput techniques, more and more gene expression analysis tend to replace hybridization-based microarrays with the revolutionary technology.The novel method encodes the category again by employing the rank of samples for each gene in each class. We then consider the correlation coefficient of gene and class with rank of sample and new rank of category. The highest correlation coefficient genes are considered as the feature genes which are most effective to classify the samples.
