  - Application data
  - GUI data
  
**Application data**  
Application data is data that is meaningful to or defined by your application. You attach application data to a figure or  any GUI component (other than ActiveX controls) with the functions setappdata and getappdata, The main differences between it and UserData are:
  * You can assign multiple values to application data, but only one value to UserData.
  * Your code must reference application data by name (like using a Tag), but can access UserData like any other property
Only Handle Graphics MATLAB objects use this property. Functions that provide access to application data:
setappdata
  * **setappdata(h,'name',value)**
  * values = **getappdata(h)**, value = getappdata(h,name), 
  * **rmappdata(h,name)**
  * **isappdata(h,name)**

**GUI data** differs from application data in that: 
  * GUI data is a single variable; however, when defined as a structure, you can add and remove fields. 
  * Application data can consist of many variables, each stored under a separate unique name.
  * You access GUI data using the guidata function, which both stores and retrieves GUI data.
  * Whenever you use guidata to store GUI data, it overwrites the existing GUI data.
  * Using the getappdata, setappdata, and rmappdata functions does not affect GUI data.

**guidata** : Store or retrieve GUI data 
<code>
data = guidata(object_handle)
guidata(object_handle,data)
</code>

**guihandles**  : Create structure of handles 

<code>
handles = guihandles(object_handle)
</code>
returns a structure containing the handles of the objects in a figure, using the value of their Tag properties as the fieldnames, with the following caveats:

  * Objects are excluded if their Tag properties are empty, or are not legal variable names. 
  * If several objects have the same Tag, that field in the structure contains a vector of handles. 
  * Objects with hidden handles are included in the structure.

<code>
handles = guihandles
</code>
  * returns a structure of handles for the **current figure**

===== Interní formát dat =====

=== Data Storage - Hierarchical Data Format (HDF5) Files  ===
 je základním formátem pro ukládání dat v programu Physioplore. Veškeré datové konverze jsou založeny na převodu dat //z// a //do// ** HDF5**. Zde jsou ukládány mezivýsledky v hiearchické struktuře, která odpovádá postupu zpracování. Podrobnosti o formátu dat jsou k nalezení na http://www.hdfgroup.org

Data s parametry lze prohlížet popř. přímo editovat pomocí programu HDFview.
