    Least Square Mass Isotopomers Distribution Analyzer (LS-MIDA) is an application for infection biology efforts, and was developed to estimate Mass Isotopomers Distribution from Spectral data by analyzing each peak of given mass and each mass atom fragment.

    It is capable of analyzing (isotopic) labeled (Carbon) metabolite based experimental raw data (different amino acids). It estimates Mass Values (minimum and maximum), predicts theoretical Values for pure compounds, draws linear relationships between masses within the range of a compound and performs linear regression analysis to predict Relative Intensity Values with respect to the each Mass to charge Ratio. To give better understanding of obtained results, LD-MIDA visualizes obtained results by drawing a Spectrometer based on mass to charge ratio values, actual relative intensity values, estimated relative intensity values and percentage of relative intensity at each mass to charge ratio. (see Figure 1)

    LS-MIDA  provides a special graphical user interface for file based experimental raw data manipulation and management which is capable of not only managing user input experimental raw data but also providing options to manage resultant data (output of LS-MIDA). It allows user to create new data files, manage created data files, merge new or already made data files into one or more new or already created files data files and manipulate entries data files. It is an independent file based data management system, doesn't require any external or third party database to install and use. (see Figure 2)

    LS-MIDA is implemented in Microsoft Visual Studio Dot Net (C#), integrating formal unified modelling language to scheme from different perspectives and incorporating human computer interaction guidelines, principles and patterns.
