Glossary
Below is a growing list of terms used inside the CING reports. Please ask us about missing information and we will add it to this glossary.
Key | Explanation |
csd | chemical shift difference |
cv | circular variance |
d1d2 | This parameter describes the CA-CB vector of residue i-1 with respect to the CA-CB vector of residue i. The plot of residue i gives two of those combined; i.e. (CA-CB)(i-1)-(CA-CB)(i) versus (CA-CB)(i)-(CA-CB)(i+1). Hence, it should be read as the conformation of residue i relative to its two neighbours i-1 and i+1. We still need to properly asses its usefulness for structure validation purposes, but limited manual assessment indicates it to be useful in identifying potential problem areas. |
distance class: intra-residual | Those distance restraints (DR) that are within the same residue |
distance class: sequential | DRs between direct neighbouring residues i and i+1 |
distance class: medium-range | DRs between residues i and i+n with n in the range [2,4] |
distance class: long-range | DRs between residues i and i+n with n over 4. This class includes the inter-chain DRs if present. |
distance class: ambiguous | DRs with more than one possible pair excluding consideration of ambiguity over stereospecific assignment (SSA). |
dr | distance restraints |
rmsd | root mean square deviation |
rog | red orange green. The ROG score is used to aid in identifying bad, poor, and normal entities such as residues, chains, molecules. |
ssa | stereospecific assignment |
