I am running NEURON on Ubuntu and it successfully works when I create my own simple files.
However, I am trying to run the Mainen and Sejnowski 1996 model in the patdemo folder. As the README.txt file states I compiled the .mod files by typing the command 'nrnivmodl'. Everything appears to compile fine as it returns the statement, 'Successfully created x86_64/special'.
However, then when I type the command 'nrngui demofig1.hoc', the shell returns the following text with an error:
