can't load mknrndll issue

Post by Sun Xiaoqing »

Good day,
I'm new at NEURON and I was wondering if someone could help me with this.

I'm trying to follow the instructions by ModelDB:
https://senselab.med.yale.edu/ModelDB/S ... e.m#tabs-1

My system is Win10 and when I double click mknrndll, these massages shows:

Can't load NEURON resources from D:\nrn;C:\nrn/lib/nrn.def[aults]

C:\nrn\bin\nrniv.exe: String is not a template

I've downloaded NEURON twice, the first time I downloaded it on D drive, and the second time on C drive.

Any ideas on how to fix this?

Thanks.

. . .
I've downloaded NEURON twice, the first time I downloaded it on D drive, and the second time on C drive.
No, you INSTALLED NEURON twice, and now you have at least one broken installation of NEURON. First thing you need to do is get rid of ALL installations of NEURON on your PC, and any traces of NEURON that may remain in MSWin's PATH. Go to C:\nrn and execute the uninstall.exe that you find in that directory. Then go to D:\nrn and execute the uninstall.exe in that directory. When you are done, there should be no C:\nrn and no D:\nrn.

Then reboot Windows, and install NEURON on the C: drive. After that, go to the NEURON program group and execute the program neurondemo. In the "NEURON Demonstrations" panel click on the radio button labeled "Release". Then in the RunControl panel click on the button labeled "Init & Run". You should see a bunch of windows, including three graphs that show plots of membrane potential, calcium currents, and calcium concentrations plotted as functions of time.

I also tried auto-launch
which didn't work because this model isn't packaged in a way that allows auto-launch to work. How do I know, without even trying it? Two ways. First, auto-launch requires the presence of a mosinit.hoc file. ModelDB entry 84589 doesn't come with a mosinit.hoc file. Second, this model DOES have a set of detailed instructions in the file eaps/docs/index.html, and those instructions don't say anything about auto-launch.

Dear Ted,

Thank you for your advice, I tried to follow your instruction but unfortunately, the first time I uninstalled D:\nrn I put it in the recycle bin then deleted it without using the uninstall.exe, so I couldn't erase the traces of D:\nrn, so I uninstall C:\nrn instead. Then when I double-clicked mknrndll, this time it worked. And the EAPS files downloaded form the ModelDB were installed in C:\.

I came across a problem when I was following the instructions.
The instructions given in the ModelDB are given as:

2.Run the Command Prompt application (under Accessories, on the start menu)
3.Change the directory to eaps. If you put the EAPS package in c:\ (the root directory) then you would use the command:

cd c:\eaps

4. Enter the following command and parameters (copy & paste):

c:\nrn59\bin\neuron.exe -dll mod\nrnmech.dll hoc/src/refs.hoc cells/d151.hoc hoc/src/file_util.hoc hoc/src/main.hoc

Since I put nrn in D:\, I changed Step 4 into :
d:\nrn\bin\neuron.exe -dll mod\nrnmech.dll hoc/src/refs.hoc cells/d151.hoc hoc/src/file_util.hoc hoc/src/main.hoc


and the result was:

Sure. Forget about Windows. Use Linux instead. The code runs without complaint under Linux. Making it work under Windows is going to be a major pain.

Re: can't load mknrndll issue

Post by Sun Xiaoqing »

Thank you for your suggestions, but the situation is that I can't change my system into Linux and I also tried some other ways to fix this problem which unfortunately failed. So I put the nrn files in D:\ which could make mknrndll work normally and I also have complied the mod file using mknrndll.

My question is:
1. Are there some other ways that I can run this model without using cmd (Command Prompt application )?
2. after removing the statement { neuron_name = "d151" , I double-clicked the eaps\cells\d151.hoc file and successfully got the shape plot.
cell_type = "ca1pyr" }
Then I tried to load other hoc files from Neuron Main Menu\File\Load hoc to load: eaps\hoc\src\file_until.hoc but and other hoc files needed for this
model, but I didn't seem to work.
3. I don't understand that with these files in the eaps folders, what should I do to apply all the hoc files to the existing neuron that I created. Is it a
must that I have to use cmd?

Thanks again for your kind response. I really appreciate your help.

Nope.
after removing the statement { neuron_name = "d151" , I double-clicked the eaps\cells\d151.hoc file and successfully got the shape plot.
cell_type = "ca1pyr" }
Then I tried to load other hoc files from Neuron Main Menu\File\Load hoc to load: eaps\hoc\src\file_until.hoc but and other hoc files needed for this model, but I didn't seem to work.
I'm not surprised. The author of this model wrote code that was supposed to protect you from such tedious details. But Windows changed and NEURON changed in ways that the author did not anticipate, so the code doesn't work any more.
I don't understand that with these files in the eaps folders, what should I do to apply all the hoc files to the existing neuron that I created. Is it a must that I have to use cmd?
The original implementation required one to use cmd. Even if someone fixed it so that it worked with the current versons of Windows and NEURON, you'd still have to use cmd.

1.

When I downloaded Anaconda, I didn't toggle the first box which asked me to add Anaconda to my Path Environment Variable, and I wonder if it was the reason why these error message s occurred.

2. As you said before, since NEURON and WIndow changed, so if I want to make this code work, I have to revise the hoc code according to the error messages generated, right? Is there going to be a huge change in the code?

Thank you so much for always answering my question, that really helps a lot.
