Reverted r13246 as different approach will be used.

The command used was:
svn merge -r 13246:13239 .

The new function vectors_xyz() in the /prompt/structure.py is not needed. The current code will be fixed for xyz file format suggested in https://mail.gna.org/public/relax-devel/2011-06/msg00244.html.

The residue numbers are now checked in GUI auto NOE analysis GUI test.

Clean up of the auto NOE analysis GUI test.

The GUI is now not shown and click events are not simulated as this is too hard to control at the
moment.

A new function vector_xyz() was generated.

A new function vector_xyz() was generated in '/prompt/structure.py' for extracting a vector of two given atoms in a xyz file.

Adding code for extracting the vector in the system test test_read_xyz_internal2()

Code for extracting a vector of two given atoms was added in the system test test_read_xyz_internal2().

The data arg to the execute_thread() method is now a proper tuple when running as a thread.

Rearranged the data checks in the NOE page to match the page layout.

The NOE page now uses the missing_data GUI dialog for missing data.

The assemble_data() method is now called outside of the thread, and the data is passed in.

The NMR frequency is now checked in the NOE page prior to execution.

This will prevent strange missing results file errors.

Fix for unresolved residues when blank in the NOE page.

The value is now converted to None.
