This tool finds the alignments in the specified RT window and extracts alignment EICs from feature alignment data using XCMS's getEIC method. 
It produces a HTML report showing the EIC plots and the mass list of each alignment. The figure below shows an example of such an EIC plot, showing also the difference between 
two classes, with extra alignment information beneath it.
