    782785
    783786=== series functions ===
    784  * 'aver_stat': calculate field average over a time series 
    785  * 'avi2png': copy an avi movie to a series of B/W .png images (take the average of green and blue color components) 
    786  * 'check_data_files': check the existence, type and status of the files selected by series.fig 
    787  * 'merge_proj': concatene several fields from series, can project them on a regular grid in phys coordinates 
    788  * 'sub_background': subtract a sliding background to an image series 
     787 * 'aver_stat': calculate field average over a time series
     788 * 'avi2png': copy an avi movie to a series of B/W .png images (take the average of green and blue color components)
     789 * 'check_data_files': check the existence, type and status of the files selected by series.fig
     790 * 'merge_proj': concatene several fields from series, can project them on a regular grid in phys coordinates
     791 * 'sub_background': subtract a sliding background to an image series
    789792 * 'time_series': extract a time series after projection on an object (points , line..)
    790793
    791794=== transform functions ===
    792  * 'ima_filter': low-pass filter of an image (builtin filtering parameter) 
    793  * 'ima_remove_background': removes backgound from an image (using the local minimum) 
    794  * 'ima_remove_particles': removes particles from an image (keeping the local minimum) 
    795  * 'FFT2_detrend': calculate the 2D spectrum of the input scalar after removing the linear trend (requires the Matlab image processing toolbox). 
    796  * 'phys': transforms image (Unit='pixel') to real world (phys) coordinates using geometric calibration parameters. It acts if the input field contains the tag 'CoordUnit' with value 'pixel' 
     795 * 'ima_filter': low-pass filter of an image (builtin filtering parameter)
     796 * 'ima_remove_background': removes backgound from an image (using the local minimum)
     797 * 'ima_remove_particles': removes particles from an image (keeping the local minimum)
     798 * 'FFT2_detrend': calculate the 2D spectrum of the input scalar after removing the linear trend (requires the Matlab image processing toolbox).
     799 * 'phys': transforms image (Unit='pixel') to real world (phys) coordinates using geometric calibration parameters. It acts if the input field contains the tag 'CoordUnit' with value 'pixel'
    797800 * 'phys_polar': this transforms the fields to polar coordinates, radius in abscissa (same unit as x, y) and azimuth in ordinate (unit =degree).
