nuccyl version history
======================

1.5.2 (050304)
--------------

- Fixed a bug that prevented nuccyl to correctly process nucleic acids with
  palindromic sequences, or containing nucleotides with identical type and name
  belonging to different chains.
- Chain name information has been added to the name of cylindrical objects
  created by the "nuccyl -cyl_3" command: cylinder name syntax is now
  chain_typebase (i.e. the cylinder representing residue U8 within chain A is
  now called A_U8 instead of just U8).


1.5.1 (040803)
--------------

- support for additional modified nucleotides (AET, G7M)


1.5 (040602)
------------

- Added new command "nuccyl -filled" for generating filled base representations
  of nucleic acids.
- Support for all modified purine and pyrimidine nucleotides within current PDB
  entries.
- Run lengths are now printed by nuccyl commands.
- "nuccyl -1/-2d/-2r/-3" syntax changed to "nuccyl -cyl_1/-cyl_2d/-cyl_2r/-cyl_3"


1.4 (040430)
------------

- Added option not to create individual base cylinder objects in order to speed
  up work with large structures.


1.3 (040429)
------------

- nuccyl now automatically detects unpaired nucleotides and outputs
  corresponding cylinder information.


1.2 (040428)
------------

- Fixed a bug with atom numbers above 999999 and residue numbers above 999.
- "nuccyl -3" now outputs an extra file "nuccyl3.problems" where all warnings
  and errors are logged.


1.1 (031120)
------------

- Added the ability to extract DNA base pair information from 3DNA output.


1.0 (031002)
------------

- First public release.
