[RASMB] SedVel60K-FDS and AOS 1.2 available

[Tom Laue]

Hi all-

SedVel60K-FDS sedimentation velocity centerpieces for the Aviv AU-FDS 
system are available from Spin Analytical (www.spinanalytical.com). The 
centerpieces are 2.5-mm deep and use standard cell housings. Sample 
volumes are 65 uL per channel, and the centerpieces are rated to 60,000 
rpm. The centerpieces are available as either charcoal-filled and 
aluminum-filled epon.
Other centerpieces available include the SedVel60K, SedVel60K-SB 
synthetic boundary, SedVel60K-BF boundary forming , SedVel60K-MM 
meniscus matching and SedVel60K-4 four-channel sedimentation velocity 
centerpiece. All of these will work with the Aviv AU-FDS.

*Your purchases fund the development of the next generation of 
analytical ultracentrifuge.*

AOS 1.2 is available from the RASMB software archive.

   1. Make hard copy of calibration parameters available
      (View/Logs/Calibration parameters...) so that users may view/print
      and save the values used to operate the steppers.
   2. Confirm problem with AOS if WindowXP "theme" is used on host
      computer. Problem is complex and results from an incompatibility
      of manifest used in handling image lists, computer boards drivers
      and ODBC connections. Fix will be made when compiler is upgraded.
   3. Release DBUtilities. These will ensure that experiment records are
      complete (incomplete records may result from unexpected program
      termination... aka crashes). The database may be compacted and the
      integrity of table links ensured.
   4. Fluorescence focus form code rewritten. Help added (click on
      'Help' button), buttons laid out to group focus determination and
      group radial calibration functions separately.
   5. Rewrite fluorescence focus stepper code to use calibration
      parameters permitting focus motor to be handled as any other
      scanning stepper. Rewrite scanner code to make stepper handling
      consistent (no separate handling for the focus stepper).
   6. Add an 'update database' function to the start up sequence.
      Previous versions of AOS software will not function properly with
      an updated database.
   7.  Update the "take single scan" button so that it toggles between
      "Start" and "Stop" operations. Allow a single scan to be stopped
      gracefully. Fix problem that caused program to crash due to an
      invalid directory if a single scan was requested prior to starting
      an experiment. Now a user may take a single scan any time the
      button is enabled.
   8. Make sure the focus lens position is reset after reset of steppers
   9. Fix problem where comport does not exist. AOS would freeze- now
      allows the user to select the correct comport
  10. Refocus objective lens after Com Port initialization
  11. Several small bug fixes and improvements as suggested in Bugzilla.

Best wishes,
Tom Laue
