* Add a script which performs the full analysis in relax for the model.  Also a script which performs the analysis using only the R2eff model.  See the '''test_suite/shared_data/dispersion/Hansen/*.py''' scripts for reference - these scripts should be copied to your data directory and modified.  Once the scripts are functional, they can be copied and modified for the truncated data.
* Copy the full analysis script to '''test_suite/system_tests/scripts/relax_disp/''' with an appropriate name(using the '''svn cp''' command).  This can then be used in a new system test.  Better still, the final save file from the '''r2eff_calc.py''' script for the truncated data can be used to start the script.  This is again to save a lot of computation time in the test.  See the '''test_tp02_data_to_ns_r1rho_2site()''' system test in the '''test_suite/system_tests/relax_disp.py''' file for a template.
If you are not a relax developer, a [https://gna.org/projects/relax support request] can be [https://gna.org/support/?func=additem&group=relax submitted].  You can attach files and add comments to that request for a relax developer to make the changes for you.
