Adding New VnmrJ Users

If you want new user to be able to access files between the 500 and 800 workstations using NFS, the user must have the same id number on both machines. To do this, you must first create the user account using the standard Linux user control panel. There you can enter the id# that you want the user to have. Give the user a password. Then proceed with making the VnmrJ account as described below.

Creating VnmrJ User Account

  • Login as vnmr1 and use VnmrJ-admin to create new users
  • Use the “standard” type of account
  • Logout and then login as the newly created user.
  • If the user does not already have a password, give one using the “passwd” Linux command

Create Icons and Setup Linux Account

  • Still logged in as new user
  • Use the Linux Screensaver control panel to turn off screen lock during screensaver
  • LinuxMenu->Preferences->Windows-> select window with rollover and title bar to rollup
  • Right-click on red exclamation icon at top right of screen and remove this icon
  • Right-click on vertical bar (“|”) in task bar at bottom of screen
  • Select “unlock” and then drag “|” about 1/3 of way to right
  • Right-click to left side of “|” in task bar
  • Select AddToPanel -> ApplicationLauncher_>SystemTools->Terminal-> then add
  • Similarly, AddToPanel->CustomApplicationLauncher, then set name to vnmrj, set command to vnmrj, click on icon and browse to /vnmr/iconlib/vnmrj.gif

Check Login File

To permit remote operation of VnmrJ, make sure the user’s .login file does not contain (or comment out) the following lines. Edit as needed.
  • echo -n 'Input display server name: '
  • set server=($<)
  • setenv DISPLAY $server":0.0"

Setup VnmrJ

  • Still logged in as the new user
  • click vnmrj icon on task bar to start VnmrJ
  • VnmrJ Menu->Edit->SystemSettings-> turn on X,Y,Z gradients for 800 and only Z gradients for 500; select realtime DSP; wysiwyg off
  • Setup->Workspace- -> create experiment 2 and maybe a few others
  • File->Printers -> select printer and select plotter
  • Open up command line by pulling down dot above graphics window

Activate Either BioPack or ChemPack

but not both. See below.

Activate BioPack

BioPack users (those wanting to use pulse sequences tailored for proteins and nucleic acids) should activate BioPack.
  • Still logged in as the new user
  • ExperimentsMenu->ActivateBioPack->CopyOfVnmr1Probefile
  • On 500, in terminal window, edit users vnmrsys/maclib/login file (create if necessary) and add following line
  • probe=‘HCN’
  • exit VnmrJ, then restart VnmrJ
  • make sure user’s default shimmap is H1_map

Activate ChemPack

ChemPack users (those wanting to use an interface tailored to the needs of small molecule NMR) should activate ChemPack.
  • Sill logged in as the new user
  • ToolsMenu->LoadChemPack
  • On 500, in terminal window, edit users vnmrsys/maclib/login file (create if necessary) and add following line
  • probe=‘penta’
  • exit VnmrJ, and then restart VnmrJ
  • check user’s default shimmap; it should be penta_someDateOrAnother
