Enhancing HMM-based protein profile-profile alignment with structural features and evolutionary coupling information.

abstract：BACKGROUND:The main research topic in this paper is how to compare multiple biological experiments using transcriptome data, where each experiment is measured and designed to compare control and treated samples. Comparison of multiple biological experiments is usually performed in terms of the number of DEGs in an arbi...
