  * ''check_data_files:'' gives the series of files selected for processing and checks their existence. The oldest modified file is indicated, which is useful to detect whether any file in a civ processing is missing (then the oldest file is not updated). For NetCDF files, the last operation made (civ1, fix1, patch1, civ2, fix2, patch2) is indicated. The details of each NetCDF file can be dispalyed by selecting it with the mouse in the list.
- * ''aver_stat'': this option provides any average over the processed files. If ['''!!NbSlice]''' is not equal to 1, the average is performed slice by slice, providing !!NbSlice results.   If a projection object is selected (check box '''[!CheckObject]'''), the field is projected before averaging. For unstructured coordinates varying for successive fields, the data is linearly interpolated on the coordinates of the first field in the series. It is then advised to project the fields on a regular grid, creating a projection object of type '''plane''' with projection mode '''interp_lin''' or ''interp_tps'''. With a projection mode 'inside' or 'outside', the global histogram of field variables on the selected region will be obtained. In the case of two input files series, the field difference will be performed like with the interface uvmat.fig. It is not possible to use more than two input series for this function.

  * ''time_series:'' this action provides a time series of the input field, possibly projected . Thus projection on 'points' lead to time series of the projected variable(s) for each point, projection by interpolation on a line will (x,time) field, while projection on a plane gives a 3D matrix, whose first index corresponds to time. Note that for a vector field, projections on a tilted line or plane give the vector components longitudinal and normal to the object. To preserve the original x and y components, introduce them as ''scalar'', not ''vectors''. In the case of two input files series, the field difference will be perfomed like with the interface '''uvmat.fig'''. It is not possible to use more than two input series for this funtion.
  * ''merge_proj'': this option allows to merge several field series in a single one. This is useful to merge fields obtained with different cameras. Select the different series, using the input option ''append''. In this case, it is generally useful to interpolate the fields on a single grid. For that purpose select a projection object of type 'plane' with projection mode 'interp_lin', or 'interp_tps' to get spatial derivative. Since the different views have their own calibration, it is important to use the option 'phys' (menu menu_coord), and to create the grid in phys coordinates.

  * ''sub_background.m'': used to removed a mean background to the images. This is useful before CIV processing when some fiked features are visible in the background (when the laser sheet is close to the bottom).
