NMP_readme_zip_files -Paul Schlosser, NCEA, U.S. EPA -September 23, 2013 The .zip files, NMP_human_9-23-13.zip and NMP_rat_9-23-2013.zip, contain sets of files that constitute workspaces for the computation software, acslX (v. 3.0.2.1, The AEgis Technologies Group, Inc., Huntsville, AL). Most of the files contained in each workspace are specific to acslX and a basic knowledge of this software is necessary to make use of them. The workspaces can be used by unzipping the corresponding .zip files. Once this is done the resulting folder will contain a workspace (.aws) file of the corresponding name (e.g., NMP_human_2013_2.aws) and a "Project 1" subfolder. The .aws can be opened from within acslX, which will then display the primary acslX program (.csl) file and scripts (.m files) for reproducing the simulations and model fits shown in the QA report, n-Methylpyrrolidone PBPK QA Report 091613 V3.docx, or used and shown in the dose-response analysis. A detailed list of scripts and their functions follow. While various files within the acslX "Project 1" folders can be viewed outside of acslX, changing them can damage their functionality. In particular .aps files set formatting for various plots and are created/edited by acslX when a user is manipulating a plot through the graphical user interface. Please do not edit them directly. ** The file Residential.xlsx in the human "Project 1" folder should not be altered, as it contains inputs for the residential exposure scenario. In the primary model (.csl) files, all changes made by the U.S. EPA are noted in comments at the end of or just above or below the altered code. Significant changes in script (.m) files are also noted with comments. In order to avoid the possibility of having some parameters assigned different values for different simulations, all parameters other than those defining exposures/scenarios have been consolidated into one or two 'param.m' scripts. Where values had been set in other scripts, these have been commented out, but there may not be explanatory commments on each instance. The document, n-Methylpyrrolidone PBPK QA Report 091613 V3.docx, is referred to as "the QA report" below.
