Version differences

[xlyang97]

Hello,
I have some problems to run the previous code. The code is established by version 7.6.2. When using 8.2.0, it has some errors due to the different versions. It seems 'axnode' is not named in latest version. Could anyone tell me how to solve it?
Thanks.

The error is as follows.
Traceback (most recent call last):

Axnode is not part of NEURON per se, that syntax is indicating it's defined by a mod file, possibly this one.

To run the code, you'll need to find the mod file and run nrnivmodl to compile the mod files.

Thanks for your reply! I have compiled the mod files as follows. However, it still have the same error.

I'm confused. I don't see the error message in the screenshot?

Although I'll add that the compilation output was suspiciously short. Are you sure the mod file was in newfolder?

[xlyang97]

The last figure shows the compile is successful. Here is the error.

hhkchan.mod file is in an empty folder 'newfolder' . After compiling, newfolder also has nrnmech.dll.
