Unfortunately on the Gateway `konqueror` which is the default program used to open `html` files, fails to show properly all structures when called from `dd_doc`.
To force usage of `firefox` and show properly all sub-structures (including the error bars), please create a xdg-open alias pointing to /gw/switm/bin/XDG-OPEN.
For instance you can perform the following command from BASH:
```echo "alias xdg-open=/gw/switm/bin/XDG-OPEN" >> ~/.bashrc```
or the following one from CSH:
```echo "alias xdg-open /gw/switm/bin/XDG-OPEN" >> ~/.cshrc```
Change will affect the next shell you open, or alternatively `source ~/.bashrc` (resp. `source ~/.cshrc`) in order to impact the current shell.
