**************************************************************************** Note: By default, each nucleotide is identified by chainId.name#. So a common case 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.
