+        (cut.py)
+        Cut the selected signal between two points.
+        With the first parameter you have to select the signal (for FS for example
+        you can select with "0" the approacing curve and 1 for the retracting
+	curve. This depend also on how many set of data you have on the graph).
+        With the second parameter you select the output name file for the selection.
+	The data is arranged in two simple column without a header, the first column
+	is the "x" data and the second the "y".
+        -----------------
+        Syntax: distance "whatset" "namefile"
