Running Ubuntu 10.04.4 LTS in a VirtualBox VM version 4.1.16. I process and analyze NMR data that is in a VirtualBox Shared Folder.

After launching nessy from the command line, I set the project folder as the directory from which NESSY launched and selected a PDB file from that same directory, then clicked next step.

The Import Peak List and Import Multiple Peak List functions did not work, so as a workaround I copied a single row from an Excel file into the appropriate row in NESSY's data matrix.

I entered the CPMG frequencies and total relaxation delay using the Set up button, set Experiment Type to CPMG Relaxation Dispersion, and Heteronculear Frequency to 60.82, then clicked next step to go to the Analysis tab, and clicked Evaluate Data, which produced this output:

Evaluating Datasets and Experiments:
==================================================
Checking if project folder is set up... [Ok]
Evaluating Experiment 1.....
=============================================
Checking if datasets are set up... [Ok]
Checking if values are entered correctly... [Ok]
Checking if reference spectrum is set up... [Ok]
Experiment 1 checked.
-----------------------------------------------------------------
1 experiment will be analyzed.

Then I clicked Start Calculation and this output was generated:

Experiment mode: CPMG relaxation dispersion.

(Note: When I tried this with a much more populated matrix of peak heights, not just one residue, the output ended with R2o: 18.821, the terminal displayed "Unhandled exception in thread started by", and the Traceback was not shown.)
