I would like to check the units in my code using NEURON's modlunit; however, it doesn't seem to be working for me. When I open modlunit and select the desired file from within the working directory, the screen flashes something very quickly and returns to the "Enter filename:" window. It appears that nothing is happening if not paying attention. What does this flash mean? What should I be seeing? How can I fix it?

If it's not complaining about anything, it didn't find any units inconsistencies. For fun,
you might deliberately introduce an error just to see what happens. For example,
start with a mod file that specifies a distributed current (WRITEs a current whose units
are in mA/cm2 and has a conductance density S/cm2), and change the units of the current
to A/cm or the conductance to uS/cm.

I have been doing just that, creating a simple mod file and changing the units to that which I know are inappropriate and should be caught by neuron. For fun I did exactly as you proposed and still only got the quick flash of the window. Changing from mA to A and cm2 to cm resulted in no complaint.

Did you look at the xterm? That's where error messages are printed.

I am running windows...

Replace nrniv.exe in the shortcut with neuron.exe and the dos boxes will remain visible if modlunit has found a mistake. At least that is what it does here (XP with nrn 5.8 Main (88)).

I suppose we call this a bug, but it is something I remembered worked well earlier. So it might be XP as opposed to W2K, NT or Win98.

Thank you.
That appears to have fixed it; however, now the dos window stays up sometimes and sometimes doesn't...when it disappears does that simply mean that no error was found?

modlunit fails to work properly under XP on my PC too. This happens with NEURON
5.9 2006-07-14 (1461), and also with 5.9 (1434). What versions are you using, Raj and
char4040? Also, which MSWin are you using, char4040?

I am running the neuron 5.9 version downloaded 6.12.06 using WinXP.
I am hoping you will find this information useful.

The critical datum is not when you downloaded the file--it's the revision number and date,
which are contained in the first line of the message that NEURON prints in its xterm when
you double click on nrngui

XP fully patched with nrn 5.8 Main (88)

As noted before replacing nrniv.exe with neuron.exe in the shortcut seems to provide a workaround.

W2K shows exactly the same problem.

with all these versions:
NEURON -- Version 5.6 2004-5-19 23:5:24 Main (81)
NEURON -- Version 5.8 2005-5-2 13:16:27 rel5_7_159 (1)
NEURON -- Version 5.8 2005-10-14 12:36:20 Main (88)

All with the same cygwin version though:
CYGWIN_NT-5.0 rajslab 1.5.19(0.150/4/2) 2006-01-20 13:28 i686 Cygwin

Workaround works forall of them.

Thanks, Raj, that's particularly useful information.

ok- neuron version 5.9 2006-06-13 1423

The bug has been fixed--install this new version
