Question: I am using Intel Fortran. Do I need to do anything special?
Answer: Intel Fortran requires an extensive set of environment variables. The easiest means to set these is to edit two lines in a file "FortranVar.bat" that is provided with the PLT Tools installation. See the User's Manual for details. Once these edits are completed, PLT Tools typically runs with no problems.

Question: I use NMQUAL to run NONMEM. Can I also use PLT Tools?
Answer: PLT Tools supports both NMFE and NMQUAL.

Question: My Fortran installation does not use nmfe6.bat (the default batch file for Windows). Instead, I wrote my own batch file to run NONMEM. Can I use PLT Tools?
Answer: In past years, because of the difficulty in installing NONMEM, some users wrote their own batch files to run NONMEM. There is no means for us to test how your particular batch file interacts with PLT Tools so we cannot support their use. If you do not have a functional version of nmfe6.bat (and one cannot be created for your Fortran compiler), we recommend that you do the following:
1. Obtain a modern Fortran compiler. For Windows and OS X, we recommend G95, available at no cost from G95.org; this compiler comes with an installer that updates your path automatically.
2. Create a second NONMEM installation (in a new folder) on your computer using the standard installation procedure (except for the designation of a different folder name).
This second NONMEM installation will include a functioning copy of nmfe6.bat in the run folder. This file can be used as part of PLT Tools. When you start PLT Tools, the installer will attempt to complete the installation procedure. If it is not successful, it will provide information as to how you can complete the procedure manually.

Question: I use Wings for NONMEM. Can I also use PLT Tools?
Answer: PLT Tools uses nmfe6.bat, a file that is created during NONMEM's default installation procedure. This batch file differs from the one used by Wings for NONMEM. Most likely, Wings for NONMEM is not compatible with PLT Tools.

Question: I use the Linux OS. Can I use PLT Tools?
Answer: Early versions of PLT Tools supported Linux. However, interest in the Linux platform was low so support was discontinued.

Question: I used PLT Tools with S-Plus in the past. The present version does not appear to support use of S-Plus.
Answer: Early versions of PLT Tools allowed use of S-Plus. However, many important features of PLT Tools were not available with S-Plus. As a result, support was discontinued.

Question: I need specialized graphics for my analysis. Can I piggyback onto PLT Tools to create these? Can PLTsoft provide these?
Answer: The user can create his/her own scripts. See Components. PLTsoft can provide scripts for additional graphics (on a consulting basis; see the Support page).

Question: How can I get rid of the footer "Uregistered version of PLT Tools" in each of the PDF documents created by PLT Tools?
Answer: Register with PLTsoft (i.e., pay the registration fee). Once you have paid, you will receive a license key. One this license key is entered, that text is replaced with "Property of COMPANYNAME (Confidential)".

Question: I have a dual-core (or quad-core) computer on which I should be able to do more than one simultaneous NONMEM run. Does PLT Tools support that?
Answer: The licensed version of PLT Tools supports simultaneous NONMEM runs. The user can designate the number of simultaneous runs permitted on a single machine (typically, the number of cores or twice the number of cores [if the cores are multithreaded]). The unregistered version of PLT Tools does not support simultaneous runs - if the user initiates a second NONMEM run, that run will start when the first run completes.

Question: I run NONMEM on a cluster of machines, accessed via ssh (or telnet, etc.). Can I use PLT Tools in that setting?
Answer: PLT Tools supports accessing machines across a network. Network access requires registration and a supplemental fee. If you are interesting in licensing the network version, please contact us.
