1. Application data
2. 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

data = guidata(object_handle)
guidata(object_handle,data)

guihandles : Create structure of handles

handles = guihandles(object_handle)

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.

handles = guihandles

• returns a structure of handles for the current figure

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.

vyhledávání podle parametrů není dosud vyřešeno
