<section begin=features/>
* Addition of [https://{{gna link|url=gna.org/users/michaelbieri |text=Michael Bieri's] }} model-free data extraction script.
* Added support for CCPN Analysis 2.1 peak lists (exported in Sparky format).
* Execution locking has been implemented to prevent threaded execution from killing relax. This will be useful for the relax GUI.
* Scripts are now run as modules rather than using execfile(), closing a security hole.
* Created the [http://www.nmr-relax.com/manual/frame_order_domain_to_pdb.html frame_order.domain_to_pdb user function ] to associate PDB files with domains in the current data pipe.
* Rewrote [http://www.nmr-relax.com/manual/frame_order_pdb_model.html frame_order.cone_pdb] to handle all of the frame order models.
* The sign of the RDC can be inverted to correct for the negative <sup>15</sup>N gyromagnetic ratio.
* The RDC and PCS back-calculation user functions now add the alignment ID to the RDC and PCS if absent to allow both data types to be back-calculated in the absence of measured data.
* The N-state model calculate() method now stores the back-calculated RDCs and PCSs and Q factors.
* The PyMOL module pymol.cmd is now available within the pymol user function class, accessible as [http://www.nmr-relax.com/manual/pymol_command.html pymol.cmd] is now available within the pymol user function class, accessible as pymol.cmd from the prompt/script interface.

=== Changes ===
<section begin=changes/>
* The molecule type can now be specified.
* Improved the diffusion tensor print out.
* [http://www.nmr-relax.com/manual/pipe_delete.html pipe.delete() ] without args will now delete all data pipes.* Added some checks to the dauvergne_protocol model-free analysis [d'Auvergne and Gooley, 2007][d'Auvergne and Gooley, 2008b] for the required previously optimised results.
* Shifted the steady-state NOE specific analysis code into its own package.
* Shifted the debug and pedantic flags into the __main__ namespace for better access from other modules.
* Citations now include the status if not 'published'.
* Created a new directory 'graphics' for all relax artwork.
* The [http://www.nmr-relax.com/manual/structure_load_spins.html structure.load_spins() user function ] now gives a RelaxWarning if no data could be found.* The negative cones and z-axes are now not created for the pseudo-ellipses in [http://www.nmr-relax.com/manual/frame_order_cone_pdb.html frame_order.cone_pdb()].* Added some transparency to the cone in [http://www.nmr-relax.com/manual/pymol_cone_pdb.html pymol.cone_pdb()].* Modified the [http://www.nmr-relax.com/manual/pymol_cone_pdb.html pymol.cone_pdb() user function ] to handle x, y, and z-axes.
* Modified create_cone_pdb() to accept a pre-made structural object and to create a file only when asked.
* Switched the names of the Pseudo_elliptic and Pseudo_elliptic2 classes.
* Parameters can be fixed to the original values during the frame order grid search.
* The user function argument checker arg_check.is_int_or_int_list() can now allow for None list elements.
* The frame order model can be overwritten by [http://www.nmr-relax.com/manual/frame_order_select_model.html frame_order.select_model()].
* Shifted to using numpy.sinc() for the frame order equations.
* Switched the theta and phi angles in cartesian_to_spherical() to match the rest of relax.
* Created a new module for performing coordinate transformations (maths_fns.coord_transform).
* The [http://www.nmr-relax.com/manual/pipe_display.html pipe.display() user function ] now places quotation marks around the pipe names and shows which is the current data pipe.* The [http://www.nmr-relax.com/manual/align_tensor_display.html align_tensor.display() user function ] now prints out the generalized degree of order (GDO) value.
* The back-calculated alignments tensors are now being stored in the current data pipe.
* Removed the docstring length check from the code validator script.
* The loading of RDCs and PCSs for non-existent spins now only throws a RelaxWarning.
* The [http://www.nmr-relax.com/manual/select_read.html select.read() ] and [http://www.nmr-relax.com/manual/deselect_read.html deselect.read() ] user functions can now accept file handles or dummy file objects.
* Limit arrays are now sent into the minfx generic interface for limiting simulated annealing.
* The [http://www.nmr-relax.com/manual/align_tensor_delete.html align_tensor.delete() user function ] can now be used to remove all tensors simultaneously.
* Made a RelaxError less stringent so that the paramagnetic centre can be unfixed.
* Initialising an alignment tensor now adds the ID to the alignment ID list.
* Changes to the NOE auto-analysis for the GUI: The output filename can be specified; The folder, where results files will be placed, can be specified; The label of heteronucleus and proton of peak lists and PDB file can be selected; The sequence is read either by sequence file or PDB file; Removed white spaces and progress output.
* Changed the alignment tensor parameter scaling back to 1 as this was slowing down the optimisation.
* The [http://www.nmr-relax.com/manual/rdc_back_calc.html rdc.back_calc() user function ] without an ID arg will back-calculate RDCs for all alignments.* Renamed the [http://www.nmr-relax.com/manual/pcs_centre.html pcs.centre() user function ] to [http://www.nmr-relax.com/manual/paramag_centre.html paramag.centre() ] to abstract for the PRE.
* Better support for RDC and PCS correlation plots with and without errors.
* Inverted the x and y axes in the RDC and PCS correlation plots.
* Better support for tensor-less N-state model optimisation.
* The [http://www.nmr-relax.com/manual/align_tensor_copy.html align_tensor.copy() ] tensor_to arg can now be None, this is useful for copying between data pipes.
* Added a function for the pseudo-elliptical cosine function, this is a numerical approximation generated by series expansion.
* Added a method for translating pymol.cmd.do() commands into specific pymol.cmd functions. This prevents problems with commands being executed asynchronously. For example images were being saved before ray-tracing was complete.

=== Bugfixes ===
<section begin=bugfixes/>
* The loading of Monte Carlo simulation data from relax 1.2 version results files has been fixed ([https://gna.org/bugs/?17361 bug #17361]).
* Bug fix for the relaxation data add_data_to_spin() function - missing data for individual spins was not properly eliminated.
* For the 1.2 results files, the data is being extracted even if the spin is not selected.
* Sparky peak lists from CCPN Analysis 2.1 can now be read ([https://gna.org/bugs/?17341 bug #17341]).* Fix for the broken [http://www.nmr-relax.com/manual/grace_view.html grace.view() user function ] ([https://gna.org/bugs/?17344 bug #17344]).* Added 'CH' and 'OT' as carbon and oxygen atoms to the internal PDB reader ([https://gna.org/bugs/?17343 bug #17343]).
* The script path is now being removed from sys.path as this was causing incorrect scripts to be loaded if multiple scripts are executed sequentially or nested.
* Fix for [https://gna.org/bugs/?17276 the 'list index is out of range' error when differently sorted peak lists, or lists with missing data are loaded (bug #17276)].
* Fix for the input of (D<sub>xx</sub>, D<sub>yy</sub>, D<sub>zz</sub>, D<sub>xy</sub>, D<sub>xz</sub>, D<sub>yz</sub>) ellipsoidal diffusion parameters.
* Fixes for some currently unused, but useful, diffusion tensor internal API functions.
* Fix for the NOE auto-analysis - the spins are now named to the value of the 'heteronuc' arg.
* Fix for the [http://www.nmr-relax.com/manual/frame_order_cone_pdb.html frame_order.cone_pdb() user function ] - the cone is already in the PDB frame, no rotation required.* Fix for the average domain rotation in [http://www.nmr-relax.com/manual/pymol_cone_pdb.html pymol.cone_pdb()].* Bug fix for the [http://www.nmr-relax.com/manual/frame_order_pivot.html frame_order.pivot() user function ] - it is now functional.* The base contents of the relax data store are no longer saved with a call to [http://www.nmr-relax.com/manual/results_write.html results.write()].* Fix for the [http://www.nmr-relax.com/manual/pcs_back_calc.html pcs.back_calc() user function ] for when multiple structures are loaded.* Fix for [http://www.nmr-relax.com/manual/rdc_read.html rdc.read() ] when neg_g_corr is set to True and the RDC list contains entries with None.* Fix for [https://gna.org/bugs/?13259 the failure of model elimination in the full analysis script (bug #13259)].
* Added a catch in iso_cone_S_to_theta() for bad order parameters > 1.
* The attached proton PDB name is no longer hardcoded to 'H' in the dauvergne_protocol auto analysis[d'Auvergne and Gooley, 2007][d'Auvergne and Gooley, 2008b].
* When loading save states, data pipe names are always converted to a string to avoid unicode problems.
* Hardcoded the factorial() function to return support for Python 2.4 and 2.5.
* Small fixes and improvements to the [http://www.nmr-relax.com/manual/rdc_back_calc.html rdc.back_calc() user function ] - align IDs are being used instead of RDC IDs so RDCs can be back-calculated even if measured RDCs are not present. And spin info is also being checked for better error reporting to the user.
* Fix for the alignment tensor rotation matrix - it is now always in the right handed universe.
* Bug fix for the RDC back_calc() function - the align_id arg was being ignored.
