    284284If the two files are both images or scalar, their difference is introduced as the input field. If one field  is an image (or scalar), while the other one is a vector field, the image will appear as a background in the vector field. This is convenient for instance to relate the CIV result to the quality of the images, or to relate vorticity to the vector field.

    286 If  two vector fields are compared, their difference is taken as the input field, and is then displayed and analysed. If the two fields are not at the same points, the velocity of the second field is linearly interpolated at the positions of the first one (using the Matlab function {griddata.m}). The color and flags are then taken from the first field.

    288288The two file series will be scanned simultaneously by '''[runplus]''' ( '->') and  '''[runmin]''' ('<-') , according to their own nomenclature. It is also possible to manually edit the second file indices '''[!FieldIndex_1] ''' to compare two fields with different indices.  If available, the time of the second field is indicated in the edit box '''[abs_time_1] ''' at the very right, below the time of the main field.
