Instrument setup

• The matlab environment must be prepared with certain information about which instrument you are trying to analyse data for.
• The instrument specific setup file must be called with arguments defining the directories containing the instrument map files, the instrument mask files and the instrument parameter files.
• Where you choose to keep the raw data files is up to you, the standard map, mask and nexus files are all provided in the libisis distribution in "libisis\matlab\Instrument_files\"

>> mapdir='Y:\mprogs\libisis\matlab\Instrument_files\mari_files';
>> maskdir='Y:\mprogs\libisis\matlab\Instrument_files\mari_files';
>> nexdir='Y:\mprogs\libisis\matlab\Instrument_files\mari_files';
>> datadir='D:\data\RAW';
>> setup_mari_inst(datadir,mapdir,nexdir,maskdir);

• It can be useful to define default instrument values for the instrument for input to homer

>> setup_mari_homer_defaults;

• IF you are going to use diagnose then you must also set the diag defaults

>> setup_mari_diag_defaults;

• Instrument specific entries must be added to the IXTdata_source object (these define the sample position and other parameters)

>> dso=setup_mari_data_source;

• mari can be substituted by 'maps', 'het' or 'merlin' eg with examples for other places to keep your instrument files etc.

>> mapdir='C:\mprogs\maps\mapfiles';
>> maskdir='C:\mprogs\maps\maskfiles';
>> nexdir='C:\mprogs\maps\nexusfiles';
>> datadir='D:\data\maps\RAW';
>> setup_maps_inst(datadir,mapdir,nexdir,maskdir);
