dSNAP Features


  • Fragment Viewer Overlay ScreenInclude your own CIF files in the analysis
  • Automatic distance/angle generation
  • Automatic chemical symmetry correction
  • 3D fragment viewer overlay screen
  • Friendlier interface and 'Quick Start' guides
  • Analysis of up to 4000 fragments and up to 20 atoms per fragment in one single run
  • Dendrogram DisplayAutomatic comparison of all fragments with each other
  • Two independant methods of clustering to determine optimum clustering
  • Highly interactive graphic displays update clustering in real-time
  • Automatic generation of distances and angles
  • Facilities to correct for local chemical symmetry

Data Evaluation:

  • 3D MMDS Plot ScreenCustomisable graphics to allow for professional looking output
  • Ability to re-run on selected subset of original input
  • Integration with Mercury or ConQuest to view structures
  • 3D viewer allows overlay of selected fragments
  • 2D viewer related selected variables to original fragment

Data Visualisation:

  • Fragment Viewer Overlay ScreenColour-coded cell displays for easy overview of results
  • CSD Refcodes displayed for fragment identification
  • Dendrogram display for similarity analysis
  • Fully interactive rotatable 3D plots
    • similar hits visibly cluster together
  • Tables of raw numerical results

Variables Analysis mode
  • Fragment Viewer Overlay ScreenSimilarity analysis performed on all variables
  • Separate graphical displays for variable results
  • Scatter plot diagrams to relate variables trends to back to structures
