nmodl_preprocessor

This program optimizes NMODL files for the NEURON simulator.
It performs the following optimizations to ".mod" files:

• Hardcode the parameters
• Hardcode the temperature
• Hardcode any assigned variables with constant values
• Inline all functions and procedures
• Convert assigned variables into local variables

These optimizations can improve run-time performance and memory usage by as much as 15%.

Installation

Prerequisites

• Python and pip
• The NMODL Framework

pip install nmodl_preprocessor

Usage

$ nmodl_preprocessor [-h] [--celsius CELSIUS] input_path output_path

positional arguments:
  input_path         input filename or directory of nmodl files
  output_path        output filename or directory for nmodl files

options:
  -h, --help         show this help message and exit
  --celsius CELSIUS  temperature of the simulation

Tips

• This program will not optimize any RANGE or GLOBAL symbols.

  • Remove them unless you actually need to inspect or modify their value at run-time.
  • Add parameters to a GLOBAL statement to preserve them.

• Remove unnecessary VERBATIM statements.
