    572572=== 8.2 The GUI geometry_calib.fig ===
    573 -''' Opening the GUI: ''' it is made visible  from the GUI '''uvmat.fig''' by  the menu bar command '''[!Tools/Geometric calibration] '''.  If calibration data already exist in the current file <!ImaDoc>, the corresponding parameters and the list of reference points are displayed. The three first columns indicate the physical coordinates and the two last ones the corresponding image coordinates. Calibration points can be alternatively introduced by opening any  xml file <!ImaDoc> with the menu bar command''' [Open] ''' of '''geometry_calib.fig'''.
    574 
    575 -''' Plotting calibration points: ''' press the button '''[Plot] ''' to visualise the current list of calibration points. The physical or image coordinates will be used in the list '''[!ListCoord]''', depending on the option blank or 'phys' in the menu '''[transform_fct]''' of ''' uvmat.fig''' .
    576 
    577 -''' Appending  calibration points with the mouse: ''' Calibration points can be manually picked out by the mouse (left button click) after a calibration image has been opened by '''uvmat.fig''' (with the option 'blank' in the popup menu '''[transform_fct]'''), and the option '''[mouse_active]''' (at the very bottom) has been selected. Zoom can be used to improve the precision, but must be desactivated for mouse selection (then move across the image by the key board directional arrows). The coordinates in pixel of the selected points get listed in the box '''[!ListCoord]''' of '''geometry_calib.fig'''. A calibration point can be later adjusted by selecting it with the mouse and moving it while pressing the left mouse button. Points can be accumulated from several images (use the key board short cuts 'p' and 'm' to move in the image series without monopolising the mouse).'''''''
     573-''' Opening the GUI: ''' it is made visible  from the GUI '''uvmat.fig''' by  the menu bar command '''[!Tools/Geometric calibration] '''.  If calibration data already exist in the current file <!ImaDoc>, the corresponding parameters and the list of reference points are displayedin the table '''[ListCoord]'''. The three first columns indicate the physical coordinates and the two last ones the corresponding image coordinates. Calibration points can be alternatively introduced by opening any  xml file <!ImaDoc> with the menu bar command '''[Import]''' of '''geometry_calib.fig'''. It is possible to import the whole information, option 'All', the calibration point coordiantes only, or the calibration parameters only.

     575-''' Plotting calibration points: ''' press the button '''[PLOT PTS] ''' to visualise the current list of calibration points. The physical or image coordinates will be used in the list '''[!ListCoord]''', depending on the option blank or 'phys' in the menu '''[transform_fct]''' of ''' uvmat.fig''' .

     577-Simple scaling: a simple scaling, in pixels/cm.
     578
     579-''' Appending  calibration points with the mouse: ''' Calibration points can be manually picked out by the mouse on the current image displayed by '''uvmat''' (left button click). This requires the activation of the check box '''[enable mouse]'''. The image coordinates (in pixels) are picked by the mouse (the option 'blank' in the popup menu '''[transform_fct]''' is automatically selected when the mouse button is pressed). Zoom can be used to improve the precision, but must be desactivated for mouse selection (then move across the image by the key board directional arrows). Points can be accumulated from several images, using the key board short cuts 'p' and 'm' to move in the image series without the mouse.  A calibration point can be adjusted by selecting it with the mouse and moving it while pressing the left mouse button. The coordinates in pixel of the selected points get listed in the table '''[!ListCoord]''' of '''geometry_calib.fig'''.

     581-''' Editing the coordinate table: '''
     582 After mouse selection, the physical coordinates  must be introduced by editing the table. To make this task easier it is possible to export the table content on the Matlab command window by pressing '''[COPY PTS]''', and copy-paste a column on the table '''[!ListCoord]''' (the column below the introduction cell is filled). A single point can be removed by the 'backward' or 'suppr' keyboard command after selecting its line on the table. The whole set of points can be removed by pressing '''[CLEAR PT]'''. They can be also removed by pressing '''[STORE PT]''', then stored in a xml file (whose path and name is listed in '''[ListCoordFiles]'''). Stored points can be retrieved by the menu bar command '''[Import/calibration points]'''.
