+     Based on the convolution recognition automatically give the distances between the peaks found.
+     The command allow also to remove the unwanted peaks that can be due to interference.
+     When you first issue the command, it will ask for the filename. If you are giving the filename
+     of an existing file, autopeak will resume it and append measurements to it. If you are giving
+     a new filename, it will create the file and append to it until you close Hooke.
+     You can also define a minimun deviation of the peaks.
+     
+     Syntax:
+     multidistance [deviation]
+     deviation = number of times the convolution signal is above the noise absolute deviation.
