ResultsFileManagement

GENIUS proposes different management for data files. we may identify two different type of file:

• "Madona" files
• SqLite files

Madona files

This format is more or mless derived from the old one used with previous Fortran tools. Thus, its format is a bit different but the principles remains the same. Here is an example of such file with its header then the data ranked by colums:

#<AM-acces:COL-V2.0>
<INIT:
 Logiciel="DOORS"
 VERSION="V10.0"
<COL:
  0 : DATE ~cal (Date)
  1 : TIME ~s (Time)
  2 : X ~m (Integration Frame X Coordinates)
  3 : Y ~m (Integration Frame Y Coordinates)
  4 : Z ~m (Integration Frame Z Coordinates)
  5 : VX ~m/s (Integration Frame X Velocity Coordinates)
  6 : VY ~m/s (Integration Frame Y Velocity Coordinates)
  7 : VZ ~m/s (Integration Frame Z Velocity Coordinates)
  8 : PSI ~deg (Integration Frame Pitch Angle)
  9 : TETA ~deg (Integration Frame Yaw Angle)
  10 : PHI ~deg (Integration Frame Roll Angle)

Note that to be interpreted, dates must have the "yyyy-mm-ddThh:mm:ss.sss" format (and the "unit" must be ~cal).

GENIUS includes classes and methods to read or write such files

// Opening it and load data
        final GPlotDataMadonaReader fileData = new GPlotDataMadonaReader();
        fileData.load(new File("EPHEM.txt"));
        
        // Recovery of the colums information
        final int nbColumnsMadona = fileData.getNumberColums(null);
        
        // Loop on the columns
        for (int i = 0; i < nbColumnsMadona; i++) {
            
            final GPlotColumnInfo colInfo = fileData.getColumnInfo(null, i);
            System.out.print("Index: " + colInfo.getIndex());
            System.out.print(" / Name: " + colInfo.getName());
            System.out.print(" / Unit: " + colInfo.getUnitName());
            System.out.println(" / Description: " + colInfo.getDesc());
            
        }
        
        // We recover only colums 2, 12, 13 & 14
        final List<Double[]> dataEphem = fileData.getColumns(null, new Integer[] { 1, 12, 13, 14 });
        
        final int nbLines = dataEphem.get(0).length;
        System.out.println("Amount of lines of data: " + nbLines);
        
        System.out.println(String.format("%s %10e %10e %10e %10e", "First line: ",
                dataEphem.get(0)[0],
                dataEphem.get(1)[0],
                dataEphem.get(2)[0],
                dataEphem.get(3)[0]));
        System.out.println(String.format("%s %10e %10e %10e %10e", "Last line: ",
                dataEphem.get(0)[nbLines-1],
                dataEphem.get(1)[nbLines-1],
                dataEphem.get(2)[nbLines-1],
                dataEphem.get(3)[nbLines-1]));
