          ( Directory : /[FOLDER NAME]/data/[USER NAME]/nmr/filename/[EXP#]/fid )
        • ser  -->   the binary data of 2D and 3D
          ( Directory : /[FOLDER NAME]/data/[USER NAME]/nmr/filename/[EXP#]/ser )

Structure Calculation software

  • CSI Chemical Shift Index   (making consensus plot) :
    1. Purpose:
      The Chemical Shift Index or CSI is a quick and robust way of deriving secondary structure information from chemical shift data. The chemical shifts of HA, CA, CB and CO can be compared to their random coil values and then assigned with an index of 1 (beta sheet), 0 (coil) or -1(helix). If you have 3 or more types of shift for a particular residue then a concensus secondary structure for your protein will be calculated.
    2. Using CSI
      Step :
      1. prepare data sets
        • chemical shift file residue name, seq ID, atom type, chemical shift
      2. generate data from CSI
        CSI  -->   a menu should then appear to select

        > display output graphics
    ps: refer to CSI Overview
  • TALOS (Torsion Angle Likelihood Obtained from Shift and sequence similarity)  (dihedral angles prediction) :
    1. Purpose:
      TALOS is a database system for empirical prediction of phi and psi backbone torsion angles using a combination of five kinds (HA, CA, CB, CO, N) of chemical shift assignments for a given protein sequence. The TALOS approach is an extension of the well-known observation that many kinds of secondary chemical shifts (i.e. differences between chemical shifts and their corresponding random coil values) are highly correlated with aspects of protein secondary structure. The goal of TALOS is to use secondary shift and sequence information in order to make quantitative predictions for the protein backbone angles phi and psi, and to provide a measure of the uncertainties in these predictions.
    2. Using TALOS
      Step :
      1. prepare data sets
        • chemical shift table files    residue name, seq ID, atom type, chemical shift
