.. index:: Browser=>Check Formula

This command is used to check which formulas can be evaluated for
the given netCDF file. All formulas listed in the :ref:`toolsformulalist` 
dialog box will be checked.

Example output:

::

   Check formula for file: c:/program files/uniplot/samples/test1.nc
   Formula directory: c:/formula/

   -----------------------------------------------------------------
   The following formulas cannot be calculated (missing channels in 
   parenthesis):

   A_min       (C_H)

   -----------------------------------------------------------------
   Formula Tree:

   Formula = A_min
       A_min(c_Ant_b h_Ant_b o_Ant_b s_Ant_b)
           c_Ant_b(h_Ant_b o_Ant_b s_Ant_b)
               h_Ant_b(C_H o_Ant_b s_Ant_b)
                   C_H missing
                   o_Ant_b(o_AntOt)
                   s_Ant_b(s_AntOt)
               o_Ant_b(o_AntOt)
               s_Ant_b(s_AntOt)
           h_Ant_b(C_H o_Ant_b s_Ant_b)
               C_H missing
               o_Ant_b(o_AntOt)
               s_Ant_b(s_AntOt)
           o_Ant_b(o_AntOt)
           s_Ant_b(s_AntOt)

In the formula tree the formula dependencies are displayed. In the example
above, the formula A_min depends on the formulas C_Ant_b, h_Ant_b, o_Ant_b
and s_Ant_b. The missing channels are marked as missing.
