Supplemental Dataset

    The VESPER program is available on Github Page.

  • Benchmark dataset of Joseph, Agnel Praveen, et al. "Improved metrics for comparing structures of macromolecular assemblies determined by 3D electron-microscopy." Journal of Structural Biology 199.1 (2017): 12-26. (20 maps).
    • Rotation, Translation, and RMSD tables (100 superimpositions per target.)
    • 1-9th columns: Rotation Matrix (3*3)
      10-12th columns:Translation Vector (3)
      13th column: log(ALCPS)
      14th column: Angle difference between the reference and current fit (theta)
      15th column: Distance of Translation between the reference and current fit (r)
      16th column: RMSD
    • Reference PDB model (Superimposed)
    • 18 metrics and DOT score tables
      Filename is formatted as [emid1]_[emid2]_[Score Type].dat
      The first row shows emid1 and emid2. From the second row, 1st column is the score. 2nd column is the model ID.
        Score types
        CCCGlobal Cross-Correlation
        SCCCLocal Cross-Correlation
        SMOCSegment based Mander' Overlap Coefficient
