The B14 model is explained in: http://wiki.nmr-relax.com/B14.

Added a README file to the sample_scripts directory to help users understand what these scripts are for.

It also explains how these scripts should be used.

Fix for the local_min_search.py N-state model sample script.

This is similar to the fix of r22926. The return_api() function call was preformed too early.
Instead of placing it after the data pipe creation, the specific analysis type is now directly
specified.

Fix for bug #22004, the conformation_analysis_rdc+pcs.py N-state model sample script not working.

This is reported at https://gna.org/bugs/?22004.

The problem was that the return_api() function call needed to be after the creation of the data pipe.

Added a check for the existence of data pipes to the return_api() specific analysis function.

Removed trailing spaces in file for Relax_disp systemtests.

Small fix in cpmg_synthetic script.
