**************************************************************************** DSSR: an Integrated Software Tool for Dissecting the Spatial Structure of RNA v1.2.8-2015jun15 by xiangjun@x3dna.org This program is being actively maintained and developed. As always, I greatly appreciate your feedback! Please report all DSSR-related issues on the 3DNA Forum (forum.x3dna.org). I strive to respond *promptly* to *any questions* posted there. **************************************************************************** Note: Each nucleotide is identified by model:chainId.name#, where the 'model:' portion is omitted if no model number is available (as is often the case for x-ray crystal structures in the PDB). So a common example would be B.A1689, meaning adenosine #1689 on chain B. One-letter base names for modified nucleotides are put in lower case (e.g., 'c' for 5MC). For further information about the output notation, please refer to the DSSR User Manual. Questions and suggestions are always welcome on the 3DNA Forum.
