User’s Question: In the linux version of PROTEUM2 when invoking, through GUI, Sample -> Archive -> Sample. The “Archive Sample” window takes ~20sec to appear. The Windows XP version is unaffected. Is there a fix for that?

Answer: It is indeed a bug (either in PROTEUM2 or linux or possibly in both). During the execution of archivesample script a command is run to check the status of the CD burner, i.e. “/usr/bin/cdrecord dev=1,0,0 -checkdrive” which causes a significant delay.

The Bruker program developers have been notified.

Update: Bruker has fixed the issue. Download this file – cdburn2.pyc (local access only) – and copy it over the existing one in “/usr/local/bn/src/misc”. Don’t forget to backup your older file, i.e.
“cp /usr/local/bn/src/misc/cdburn2.pyc  /usr/local/bn/src/misc/cdburn2.pyc.old” Please also note that this fix is only for the PROTEUM2 Version 2010.9-1.

User’s Question: How do I access the Facility’s NAS from linux?

Answer: Follow this procedure:

  • Change to root:
    $ su
  • Create mount point:
    $ mkdir /elara
  • Mount NAS share:
    $ mount -t cifs -o username=ID1,uid=ID2,gid=G,noserverino //elara.bioc.cam.ac.uk/ID1 /elara
    replace ID1, ID2, G as follows:
    ID1 – your userid on the Facility’s NAS
    ID2 –  your userid on the linux computer
    G – your groupid on the linux computer

User’s Question: How do I launch PROTEUM2 software in linux?

Answer: Type “proteum” (without quotes) into the command prompt.

User’s Question: I am running a linux box, PROTEUM2 software is installed,  and starts fine. But when I try to “open sample”, I get some weird error messages.

Answer: Quit PROTEUM2. As user (not as root) type the following into the command prompt: “/usr/local/bn/bin/postgres -D /usr/local/bn/data-8.3” (without quotes) press enter then start PROTEUM2 as normal.

User’s Question: The diffraction images in the image viewer of PROTEUM2 look very dark/pale, like overexposed/underexposed. I can adjust the view using the sliders but fed up with it. Is there another way to do it?

Answer: Yes, use the automatic level adjustments. Place your mouse cursor at the end of the image file name, left mouse click, then press Enter on the keyboard and enjoy…

Users’s Question: I want to use MOSFLM to process the data I’ve collected on ICARUS!?

Answer: Coming soon. The manual will be posted in the Documentation Section of the website as soon as it’s done.

User’s Question: How does the ICARUS compare to the old machine, BCX3?

Answer: Firstly, here is a quick reminder what both machines are:
BCX3: Rigaku Ru-H3R generator, Osmic Blue optics, RAXIS IV++ image plate.
ICARUS: Bruker MICROSTAR generator, HELIOS MX optics and PLATINUM135 CCD.

As for the comparison, see for yourself… Here are the images of the two diffraction patterns taken from the same crystal, roughly in the same orientation, using BCX3 and ICARUS. Both diffraction patterns were displayed and saved as image files in MOSFLM.
