Fix for the showing of the spin viewer window in the GUI tests.

The show_tree() method of the main GUI window class was not calling the custom
self.spin_viewer.Show() method, as required to set up the observer objects required to keep the spin
viewer window updated. The value of status.show_gui was blocking this. Instead the show argument
of this Show() method is being set to status.show_gui to allow the method to always be executed.

Created the Structure.test_atomic_fluctuations system test.

This will be used to implement the idea of the structure.atomic_fluctuations user function.
........

Another small fix for the Structure.test_atomic_fluctuations system test.

The matrix diagonal was incorrect.
........
r27122 | bugman | 2014-12-18 10:03:26 +0100 (Thu, 18 Dec 2014) | 6 lines

Implemented the structure.atomic_fluctuations user function.

This is loosely based on the structure.web_of_motion user function and is related to it. The user
function will write to file a correlation matrix of interatomic distance fluctuations.
........

Created 4 unit tests for the lib.io.swap_extension function.

This is in preparation for implementing the function.
........
r27124 | bugman | 2014-12-18 10:35:22 +0100 (Thu, 18 Dec 2014) | 5 lines

Implemented the lib.io.swap_extension() function.

This is confirmed to be fully functional by its four unit tests.

r27125 | bugman | 2014-12-18 11:05:44 +0100 (Thu, 18 Dec 2014) | 11 lines

Created the empty lib.plotting package.

This follows from the thread at http://thread.gmane.org/gmane.science.nmr.relax.devel/7444.

The package will be used for assembling all of the data plotting capabilities of relax. It will
make support for different plotting software - Grace, OpenDX, matplotlib, gnuplot, etc - more
coherent. This will be used to create a software independent API for plotting in relax. I.e. the
plotting software is chosen by the user and then the data output by the user function passes into
the lib.plotting API which is then passed into the software dependent backend in lib.plotting.
........
r27126 | bugman | 2014-12-18 11:15:34 +0100 (Thu, 18 Dec 2014) | 7 lines

Created the Structure.test_atomic_fluctuations_gnuplot system test.

This checks the operation of the structure.atomic_fluctuations user function when the output format
is set to 'gnuplot'. This will be used to implement this option. The current gnuplot script
expected by this test is just a very basic starting script for now.
........
r27127 | bugman | 2014-12-18 12:05:07 +0100 (Thu, 18 Dec 2014) | 7 lines

Created the lib.plotting API function correlation_matrix().

This is the lib.plotting.api.correlation_matrix() function. It will be used for the visualisation
of rank-2 correlation matrices. The current basic API design here uses a dictionary of backend
functions (currently empty) for calling the backend.
........
r27128 | bugman | 2014-12-18 12:07:24 +0100 (Thu, 18 Dec 2014) | 6 lines

Implemented a very basic gnuplot backend for the correlation_matrix() plotting API function.

This is in the new lib.plotting.gnuplot module. It creates an incredibly basic gnuplot script for
visualising the correlation matrix, assuming a text file has already been created.
........
r27129 | bugman | 2014-12-18 12:13:07 +0100 (Thu, 18 Dec 2014) | 6 lines

Enabled the gnuplot format for the structure.atomic_fluctuations user function.

This uses the plotting API correlation_matrix() function for visualisation. The change allows the
Structure.test_atomic_fluctuations_gnuplot system test to pass.
........
r27130 | bugman | 2014-12-18 12:23:42 +0100 (Thu, 18 Dec 2014) | 8 lines

Shifted the matrix output of the structure.atomic_fluctuations user function into lib.plotting.text.

The new lib.plotting.text module will be used by the relax library plotting API to output data into
plain text format. The current correlation_matrix() function, which has been added to the API
correlation_matrix() function dictionary, simply has the file writing code of the
structure.atomic_fluctuations user function. This significantly simplifies the user function.
........
r27131 | bugman | 2014-12-18 12:25:01 +0100 (Thu, 18 Dec 2014) | 3 lines

Fix for the structure.atomic_fluctuations user function backend.

The pipe_control.structure.main.atomic_fluctuations() function no longer opens the output file.
........
r27133 | bugman | 2014-12-18 12:30:37 +0100 (Thu, 18 Dec 2014) | 6 lines

The gnuplot correlation_matrix() plotting API function now creates a text file of the data.

The lib.plotting.gnuplot.correlation_matrix() function now calls the
lib.plotting.text.correlation_matrix() function prior to creating the gnuplot script.
........
r27134 | bugman | 2014-12-18 16:08:32 +0100 (Thu, 18 Dec 2014) | 8 lines

Significantly expanded the gnuplot script from via the correlation_matrix() plotting API function.

This is for the structure.atomic_fluctuations user function. The output terminal is now set to EPS,
the colour map changed from the default to a blue-red map, labels have been added, the plot is now
square, and comments are now included throughout the script to help a user hand modify it after
creation.
........
r27135 | bugman | 2014-12-18 16:17:41 +0100 (Thu, 18 Dec 2014) | 3 lines

structure.atomic_fluctuations user function.
........
r27137 | bugman | 2014-12-18 16:46:11 +0100 (Thu, 18 Dec 2014) | 5 lines

Docstring fixes for the Structure.test_atomic_fluctuations_gnuplot system test.

This was pointing to the structure.rmsd user function instead of structure.atomic_fluctuations.
........
r27138 | bugman | 2014-12-18 18:07:19 +0100 (Thu, 18 Dec 2014) | 8 lines

Fixes and improvements for the gnuplot correlation_matrix() plotting API function.

This is for the structure.atomic_fluctuations user function. The "pm3d map" plot type is incorrect
for such data type, so instead of using 'splot', 'plot' is being used instead. The resultant EPS
file is now much smaller. The colour map has also been changed to one of the inbuilt ones for
higher contrast.
........
r27139 | bugman | 2014-12-18 18:55:27 +0100 (Thu, 18 Dec 2014) | 6 lines

Forced the gnuplot correlation_matrix plot to be square.

Created the Structure.test_atomic_fluctuations_angle system test.

This will be used to implement the mapping of inter-atomic vector angular fluctuations between
structures via a new 'measure' keyword argument for the structure.atomic_fluctuations user function.
........
r27144 | bugman | 2014-12-19 11:23:46 +0100 (Fri, 19 Dec 2014) | 7 lines

Implemented angular fluctuations for the structure.atomic_fluctuations user function.

This adds the measure argument to the user function to allow either the default of 'distance' or the
'angle' setting to be chosen. The implementation is confirmed by the
Structure.test_atomic_fluctuations_angle system test which now passes.

r27147 | bugman | 2014-12-19 16:42:53 +0100 (Fri, 19 Dec 2014) | 7 lines

Added the 'parallax shift' measure to the structure.atomic_fluctuations user function.

The parallax shift is defined as the length of the average vector minus the interatomic vector. It
is similar to the angle measure however, importantly, it is independent of the distance between the
two atoms.
........

Updated the gnuplot scripts to be executable.

These are the scripts created by the gnuplot specific correlation_matrix() plotting API function.
The file is made executable and the script now starts with "#!/usr/bin/env gnuplot".

Implemented ordinary_least_squares function the repeated auto-analysis.

Inspection of statistics books, shows that several authors does not recommend using regression through the origin (RTO).

From Joseph G. Eisenhauer: Regression through the Origin
- RTO residuals will usually have a nonzero mean, because forcing the regression line through the origin is generally inconsistent with the best fit.
- R Square measures (for RTO) the proportion of the variability in the dependent variable "about the origin" explained by regression.
This CANNOT be compared to R Square for models which include an intercept.

From "EXPERIMENTAL DESIGN AND DATA ANALYSIS FOR BIOLOGISTS", G. P. QUINN, MICHAEL J. KEOUGH
- minimum observed xi rarely extends to zero, and forcing our regression line through the origin not only involves extrapolating the regression line
outside our data range but also assuming the relationship is linear outside this range (Cade & Terrell 1997, Neter et al. 1996).
- We recommend that it is better to have a model that fits the observed data well than one that goes through the origin but provides a worse fit to the observed data.
- residuals from the no-intercept model no longer sum to zero.
- usual partition of SSTotal into SSRegression and SSResidual doesn’t work.
