C for ideas what else include in your own rootlogon. This macro requires DMT package. Macro uses objects and functions from DMT package to fill object WaveDataTD with data from frame files. The list of frame file names and channel names are specified inside macro body. Copy this macro to your working directory and edit it if you want to access frames from other files or other channels.
DMT package allows transparent reading of data across frames and files boundaries.
Macro 'ReadDataSample' will warn user if data being read across boundaries are not continious. Frequency resolution of the spectrum depends on the window length, which may be any positive number, but numbers with big prime divisors should be avoided, othervise Fourier transform takes too much time. Macro plots spectrum between frequencies f1 and f2. For this macro to work the object 'td' must have correct sampling rate defined in data member td.
