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.
