Standalone Version Installation

  • Download the homer gui standalone zip file
  • Unzip all files
  • Double click "mcrinstall.exe" And follow the onscreen instructions. This creates the matlab runtime components so that libraries required by homer are installed.
  • Run the file homer_ver0.exe to start homer


Matlab / Libisis version

This is typically contained in the folder applications/homer_gui . In matlab, when running libisis simply type

  • >> homer_ver0

To open the homer gui


Instrument Setup

To set up the Homer GUI interface you must define instrument related directories in the text files located in the instrument_setup folder contained in the main folder. Each instrument has it's own text file. There is also a file called required_fields.txt that contains the field names that MUST be entered. This may also be changed (but not deleted).

For each instrument, there are five directories which need to be defined.

input/output directories

  • indat.datadir -> this is where your raw data is kept
  • indat.spedir -> this is where homer will write the SPE file to

parameter directories

  • indat.mapdir -> this is where your instrument map files are kept
  • indat.maskdir -> this is where your instrument mask files are kept
  • indat paramdir -> this is where your instrument parameter files are kept

These files for each instrument are supplied with the libisis distribution in ./matlab/Instrument_files. An example set for the mari instrument is defined below, there are many other values which are defined in this file, ask your instrument scientist if there are any particular default settings which have been changed for your experiment, such as whitebeam integration limits or background subtraction limits.

if strcmp(instname,'mar')
:
   indat.datadir='C:\mprogs\RAW\';
   indat.mapdir='C:\mprogs\libisis\Instrument_files\mari_files\';
   indat.maskdir='C:\mprogs\libisis\Instrument_files\mari_files\';
   indat.spedir='C:\mprogs\mari_spe\'; % defines the directory to output SPE files to
   indat.paramdir='C:\mprogs\libisis\Instrument_files\mari_files\';
:
end
