    Integrative Data Analysis Platform (IDAP)

  • IDAP is a general-purpose software package for simulation and data fitting. The main feature of IDAP is its ability to simultaneously fit different types of data. Each data set may have its own equations with some of the parameters shared with other datasets/equations. This way one has global fitting parameters, which are optimized with respect to all data, as well as local ones only fit against the specific dataset. The software is developed using MATLAB object-oriented language to allow easy modification and extension by the user.
  • The most developed uses of IDAP are
    • fitting of one-dimensional NMR spectral line shapes to obtain thermodynamic and kinetic information.
    • simulation of two-dimensional NMR line shapes for complex ligand-binding mechanisms (IDAP Model Library for TITAN)
    • ITC data analysis
    • Ultrafast transient absorption (TA) data analysis
    • Reaction Kinetics analysis from NMR data
  • Documentation to IDAP is online as well as included with the code. Online Manual
  • To obtain IDAP: please, email Evgenii Kovrigin at  evgueni [dot] kovriguine [at] gmail [dot] com
    The IDAP code is free to academic scientists subject to terms of an academic license. A commercial license is available to for-profit users.
