We have enabled the ability for TEM users to drive the collection of Cryo-EM workstations remotely (ie without needing to be on site at SLAC nor on being on the SLAC computer networks). This is achieved using a combination of VNC software and web-based X-servers.
In order to gain access to the remote sessions you must first:
- Have a valid SLAC unix account
- Have access to a web browser
- Be able to communicate to SLAC via http to port 3443 from your laptop/workstation etc. (local policies on firewalls differ, please see your local IT staff)
- Be on an active experiment
- You may need a high resolution monitor for the best experience (eg, a 4K monitor is advised)
Instructions
Open the following link in a web browser
https://fastx.slac.stanford.edu:3443/
Log in with your SLAC Unix account credentials.
- Click on 'Launch Session'
- In the popup that appears, you will see a list of "Bookmarks" on the right
- select 'Cryo-EM'; the icons should show 'Cryo-EM - TEM1' etc.; if your experiment has been assigned to TEM2, choose "Cryo-EM - TEM2".
- the box underneath will populate with the appropriate command line - no need to change
- Click 'Launch'
- Enjoy!
Please note that the fastx session is persistent; ie if you close your browser, you can rejoin at any time by visiting the website again and selecting the relevant session.
Please note that a 'native' client is also available that has been reported to be a little more responsive. It also enables clearer separation of the EPU/SerialEM screen and the Gautam K2 consoles. It is available for download via a link in the bottom right corner of the webpage. Please use https://fastx.slac.stanford.edu:3443/ as the "Url"
