Isotopo
Isotopo is an application with the ability of performing quantitative mass spectrometry to readily mixtures of materials labeled with stable isotopes.
Isotopo is the ability of processing experimental isotopomers data (output of GC-MS) and provides obtained results (output) both in textual and visual formats, for better understanding and analysis. Processable (input) data consists of following elements i.e. Metabolite Information, Mass to Charge Ratio (M/Z) Values, Actual Relative Intensity (RI) Values and Standard Relative Intensity Values and Number of Carbon Atom Fragments. Isotopo is capable of analyzing three RIs value sets observed during GC-MS experiment against one M/Z value set with one Standard RI value set. The resultant (output) information is consists of following results i.e. Mass Calculations (Mo, M-1, M maximum), Natural Abundances (NA), Relative Abundances (RA), Fractional Molar Abundances (FRA), Absolute Enrichment, Mean RA, Standard Deviation RA and a Spectrum of calculated RA. It provides output of each processed RI along with average of three.
Isotopo also provides a file based and database management system for efficient experimental data manipulation and management.
Isotopo is implemented in Microsoft Visual Studio Dot Net (C#), following V-Model SDLC, integrating formal unified modelling language to scheme from different perspectives and incorporating human computer interaction guidelines, principles and patterns.
The freely available package for any non-commercial use includes a tutorial and allows robust data management of multiple labelling experiments
The most recent and available version of Isotopo provide various enhancements (as compared to LS-MIDA), including improvement in the matrix calculations, iterative refinement, quality control and mathematical validation, statistics on results, automatic data extraction / import / export and database management system.
