iMOD User Manual version 5.2 (html)


9.1PRF-files

During the start-up of iMOD the iMOD preference file is read to instruct iMOD to operate with the correct settings. These settings are placed in the IMOD_INIT.PRF file, or in a *.PRF file saved by the user.

Example of a PRF-file:

USER ‘D:\IMOD\IMOD_USER’
DBASE ‘D:\IMOD\DBASE’
MODFLOW ‘D:\OSSDELTARES\IMODFLOW_X64_R.EXE’
TOP25 ‘D:\TOP25\BMPCRD.CRD’
SUBSURFEXDBASE ‘N:\UNITS\DBASE’
7ZIP ‘C:\PROGRAM FILES\7-ZIP\7Z.EXE’
PLUGIN1 ‘D:\IMOD\PLUGINS’
FFMPEG ‘D:\THIRD_PARTY_SOFTWARE\FFMPEG.EXE’
FFPLAY ‘D:\THIRD_PARTY_SOFTWARE\FFPLAY.EXE’
VLCPLAYER ‘C:\PROGRAM FILES (X86)\VIDEOLAN \VLC.EXE’

Note: It is allowed to use any system variables in the names, such as:
USER ‘D:\IMOD\IMOD_USER\%USERNAME%’

iMOD replaces the content of the %USERNAME% variable internally. Multiple system variable definitions are allowed in a single entry line.

The following keywords can be included in the *.PRF file:

Note: iMOD will search for the IMOD_INIT.PRF file in the same folder from where iMOD is started. If such a file can not be found, iMOD will ask to create its own, with the minimal required keyword: USER. In the USER folder the following subdirectories are created when you start working in iMOD:

{IMOD_USER}\IMFFILES – storage of iMOD MetaFiles (*.IMF)
{IMOD_USER}\TMP: storage of temporary files;
{IMOD_USER}\LEGEND: storage of legend files (*.LEG);
{IMOD_USER}\MASKS: storage of maskfiles (*.MSK);
{IMOD_USER}\RUNFILES: storage of runfiles (*.RUN);
{IMOD_USER}\SOLIDS: storage of SOLID-folders (*.SOL and *.SPF);
{IMOD_USER}\SETTINGS: storage of setting-files (*.*);
{IMOD_USER}\SHAPES: storage of shape-file (*.GEN; *.SHP);
{IMOD_USER}\STARTPOINTS: storage of startingpoint (*.ISP).
