MESSAGE REGARDING NONMEM 7.4: PLT Tools is now available for NONMEM 7.4. If you installed NONMEM 7.4.0, then installed NONMEM 7.4.1 (a bug fix) and PLT Tools continues to run NONMEM 7.4.0, please see the User's Manual for instructions.

PLT Tools is available for download as a ZIP archive that contains PLT Tools , all necessary files, a User's Manual with installation instructions, and examples to familiarize a user.  The downloadable version includes all features.

  1. I will not reverse engineer the code for PLT Tools

  • Linux: Due to lack of interest in PLT Tools for Linux, Linux is no longer supported.
