3.4 Common Problems and their Solutions

Off course, the administrator can never forget to install the Solaris^TM Patches. Specifically to VnmrJ^TM, after adding a new user, you also need to rerun dbupdate as vnmr1 from the Unix prompt.

You cannot move to a certain experiment library, say Exp3, and get the message ``Forground process active'':

try unlock(3), for Exp3. If it does not work, open a unix terminal, type rm $HOME/vnmrsys/lock*.
Go to Vnmr(J) prompt and retry jexp3

Vnmr(J) display wrong colors in the middle spectrum window (Solaris^TM only)

There are different reasons for that. Try to close Netscape or colorfull applications running and restart Vnmr. See the Section 3.3 to possibly avoid these problem in the future.

You type svf('filename') and has the error message ``cannot create file filename.fid'':

you are maybe in wrong directory. Type cd in Vnmr(J) prompt if you want to save in your home directory. Alternatively check if expN existis with explib

Library does not work:

In VnmrJ (not in classical Vnmr) you can not see the library info (about the expN experiments) on the left-button side of VnmrJ window. You probrably changed user configuration, added a new user or so and did not run dbupdate. Run dbupdate as vnmr1 from the Unix prompt.

Cannot open expt:

you cannot open your own saved expts. Check the following:

• Check if the library directory gives permission. For example, if you are in exp1, open a Unix prompt and type
  ls -l $vnmruser|grep exp1.
  The first column of the output must be sth like drwxr-xr-x. If the 2nd, 3rd, and 4th charachters are not rwx, type in a Unix shell
  chmod u+rwx $vnmruser/exp1
  You better try man chmod to understand what you are doing.
• Check if the subdirectories datdir and acqfil exist inside $vnmruser/exp1
• If you are running VnmrJ, try to open the same expt with Vnmr (type vn in the Unix shell). If you can open, login as vnmr1 and run dbupdate.
