 The [AOIScanPath](../../../argaze/#argaze.GazeFeatures.AOIScanPath) class provides some advanced features to analyse it.
 
-#### String representation
+#### Letter sequence
 
 When a new [AOIScanStep](../../../argaze/#argaze.GazeFeatures.AOIScanStep) is created, the [AOIScanPath](../../../argaze/#argaze.GazeFeatures.AOIScanPath) internally affects a unique letter index related to its AOI to ease pattern analysis.
-Then, the [AOIScanPath str](../../../argaze/#argaze.GazeFeatures.AOIScanPath.__str__) representation returns the concatenation of each [AOIScanStep](../../../argaze/#argaze.GazeFeatures.AOIScanStep) letter.
+Then, the [AOIScanPath letter_sequence](../../../argaze/#argaze.GazeFeatures.AOIScanPath.letter_sequence) property returns the concatenation of each [AOIScanStep](../../../argaze/#argaze.GazeFeatures.AOIScanStep) letter.
 The [AOIScanPath get_letter_aoi](../../../argaze/#argaze.GazeFeatures.AOIScanPath.get_letter_aoi) method helps to get back the AOI related to a letter index.
 
 ``` python
 # Assuming the following AOI scan path is built: Foo > Bar > Shu > Foo
 aoi_scan_path = ...
 
-# String representation should be: 'ABCA'
-print(str(aoi_scan_path))
+# Letter sequence representation should be: 'ABCA'
+print(aoi_scan_path.letter_sequence)
 
 # Output should be: 'Bar'
 print(aoi_scan_path.get_letter_aoi('B'))
