Can Myosotic SignaPoint work with audio signals?
Myosotic SignaPoint can analyze audio signals as seamlessly as it analyzes biological signals. The audio signals should first be converted to ASCII format recognizable by SignaPoint.
Please type the following commands in a MATLAB environment in order to convert .WAV audio format into comma-delimited ASCII format.
[y,Fs,bits] = wavread('Source.WAV');
dlmwrite('Converted.csv', y, ',');
where Source.WAV is the file-path of the original audio file and Converted.csv is the file-path of the converted ASCII file. You should specify the scan frequency value stored in Fs as the scan frequency of the converted file when opening it with Myosotic SignaPoint.

Can Myosotic SignaPoint work with MATLAB signals?
Myosotic SignaPoint can analyze MATLAB signals as
well. The MATLAB signals should first be converted to ASCII format recognizable by SignaPoint.
Please type the following commands in a MATLAB environment in order to convert .MAT MATLAB format into comma-delimited ASCII format.
y = load ('Source.mat');
dlmwrite('Converted.csv', y, ',');
where Source.mat is the file-path of the original MATLAB file and Converted.csv is the file-path of the converted ASCII file and 'y' is the name of the variable present in the MATLAB file.

Why can't I view a Power Spectrum signal?
Original signals and Power Spectrum processed signals can't coexist on the same Workspace. The Power Spectrum function displays the power spectrum processed signals in a new "frequency-domain" Workspace. If the Power Spectrum Workspace is closed the Power Spectrum signals can't be displayed. Simply run the Power Spectrum analysis again in order to view the Power Spectrum signals.

Why can't I see the entire information
panel below the Workspace?
Please change the resolution of your
screen display to more than 1152 by
864 pixels. You may change the
resolution by going to Start ->
Settings -> Control Panel -> Display
-> Settings -> Screen
Resolution.
Alternatively, you may select
View -> Uncheck the Signals List
from the command menu; the entire
signals list will disappear as a
result. The horizontal information
panel below the Workspace will
become entirely visible regardless
of the chosen resolution. If you
would like to view the list of
signals, you may follow the same
steps in order to make the list
visible again.
