To work the the graphical interface (nsys-ui) you can either (1) download the `.qdrep` file to your local machine or (2) create a graphical desktop session on [https://mydella.princeton.edu](https://mydella.princeton.edu/) or [https://mystellar.princeton.edu](https://mystellar.princeton.edu/). To create the graphical desktop, choose "Interactive Apps" then "Desktop of Della/Stellar Vis Nodes". Once the session starts, click on the black terminal icon and then run:

```
$ /usr/local/bin/nsys-ui myprofile_*.nsys-rep
$ nsys-ui myprofile_*.nsys-rep
