The *Advanced Options* submenu item is visible in the *File* menu only if a project structure is displayed. There are three types of *Advanced Options* submenu, the instructions which are presented after the main text of the structure under consideration. An instruction for each item begins after a blank line with a line containing the keyword. This submenu contains three items: *Advanced Output*,* Advanced Scanning* (including 1D Table or Equation(s) or 2D Equations scanning) and *Interdependent Parameters *(IDP, including Littrow Samples). The *Advanced Options* submenu adds starter examples of *Advanced Options* for the structure or deletes the existing record.
 The *Advanced Output* allows the user to add formulas for more output columns based on diffraction order values. The *Advanced Output* can be used either alone or in conjunction with *Advanced Scanning* or with *Interdependent Parameters*. The values of the *Advanced Output* can also be used to construct the *Criterion Function* for the optimization process.
 The *Advanced Scanning* allows the user to define scanning with allowable set of parameters present in the project structure file. Restrictions apply only to parameters whose values change the position (row and column indices) of other parameters in the structure text. This option is analogous to the command line option but without need to use additional external code and this option is significantly faster. In addition the *Advanced Scanning* of 1D Equation type can be used during *Optimization* process.
 The *Interdependent Parameters* means a set of dependencies imposed on a set of parameters used for scanning process defined in *Settings -> Scanning Page*. These conditions also can be used during *Optimization* process.
 *Advanced Scanning* and *Interdependent Parameters* options are potentially incompatible and cannot be used simultaneously.
 Instructions for the software to perform *Advanced Options* are contained in the main file after the structure. To edit these instructions, it is recommended to use the integrated software editor.
