On a given selection of data displayed in the Analysis window, the program can calculate and
report the selected parameters. These are displayed across the top of each channel in the
channel bar. By selecting the Send To Journal items in the Tools menu (or right-click menu),
these values for the selected parameters can be sent to a part of the DataTrax2 program called
the Journal. From any of the Channel menus (or right-click) you can add data and titles to the
Journal. Copying of the channel display is accomplished using the Copy Graph option.
Journal The Journal is an internal word processing application capable of accepting calculated
numbers from the Analysis, FFT, or XY window, as well as copied graphs from any window. In
addition to values and pictures, text can be put into the Journal using the keyboard. This allows
lab reports or explanatory documents to be composed without having to leave the DataTrax2
program.
Calculations In the Analysis window, data can be reduced using mathematical operators like mean or
maximum. These operators generally take a selection of data, operate on it and produce a
single number as a result.
A second and quite different type of analysis requires that an entire set of data be trans-
formed, point for point, into a completely different, but related set of data. Transforming data
into its first derivative is a good example of this type of analysis. DataTrax2 software includes
several of these Wave-to-Wave transforms in the Add Function menu of each channel.
The list of available functions is always expanding. DataTrax2 V2.0 includes: Periodic
Functions, Integrals, Derivatives, Channel Math, Filter, Smoothing, Power, Spirometry,
Cardiac, EEG, Multipoint Calibration and Gain Telegraph.
These calculations are also available in the Function list on the Channel Page of the Prefer-
ences dialog window. Functions typically used on signals recorded in a biology lab are listed.
Functions can be changed and these modifications can be saved in new settings files stored in
the Settings Groups.
