 The package is a multi-platform tool that has been tested on Linux, MAC and Windows systems. 
 It provides an optimized data model to allow loading large MS imaging datasets in low resource computers. MS data is stored in the hard disk drive (HDD) but rMSI is able to access data as if it where kept in computer’s memory using a virtual memory technology. The package also provides a graphical user interface (GUI) to facilitate MS imaging data exploration in R platform.
