What is new in SignaPoint 2010?
Myosotic SignaPoint and SignaBrowse
applications are now connected! That step allows researchers, to search signals, order them (by RMS, Number of zero crosses, Area and other factors) and
selected which one to be displayed in SignaPoint environment. It removes tedious
process of consequent opening of many files, selecting needed signals and
removing signals from signals' list to keep only required ones. On double click
on certain signal SignaPoint is started automatically and selected signal is
included in signals' list. When more signals are selected user can open them
using right mouse click and "Open" menu option.

New functional improvements:
Several new functions have been introduced by customer request: Remove mean,
include SUBSET Macro defining interval and allow further processing on that
interval with
another macro functions, possibility for multiple inclusion of IIF filter in
same macro, smooth filtering through Bartlett window.

What is new in SignaPoint 2009?
Myosotic keeps improving its main product-
SignaPoint- according to the client’s requirements and new updates in software
technology and signal processing. SignaPoint has several new features and
improvements over the previous versions:
- Time-PSD:
This option represents (non-stationary) signal frequency distribution in time.
User can define the number of windows and window shape used for Power Spectral
Dencity (PSD) analysis. PSD curve for every window is calculated and all the
calculated curves build a 3D graph of Time-PSD signal representation. User
friendly dialog allows the user to rotate/zoom 3D graph and observe details of
more complex figures. Such option is valuable for tracing signals frequency
occurrence in time.
- Automatic
registration:
SignaPoint does not require anymore a dongle to work with single copy of the
product. Newly installed version of SignaPoint will require a registration code.
Such code will be sent from Myosotic, LLC in 24 hours after the payment was
received. After entering the code, application automatically contacts
registration server and become activated. Every single code activates only one
copy of SignaPoint software. Dongle activated copies of SignaPoint are available
per request.
-
Function fixes and
improvements:
The new version of Myosotic SignaPoint fixes smooth filter delays
using the back-filtering of the signal with same delay. Functions as ‘Envelope’
produce a signal, which is overlapping the original signal and is not anymore
delayed in time.
Another exciting feature is the automatic calculation of mean and
median frequencies along with calculating PSD of the signal. Mean and median
frequencies appear as part of the PSD signal properties.

Macros
Myosotic SignaPoint offers fully automated macro-based signal processing
functionality. The SignaPoint macros can operate with multiple signals - as
many signals as selected. To run the macro sequence, please follow the below
steps:
1. Create a New Macro or if already created – set the macro as an active
macro.
2. Select (highlight) the signals which need to be processed.
3. Run Active Macro.
4. Results are presented in the Signals List as new signals (if the processing
result is a data vector) or listed in the “Immediate Signal Analysis” area (if
the processing result is a data/text value). If the results from the
macro function processing are data/text based, they may be copied onto the
clipboard and pasted into any other application as text/data values.
No additional information is needed during macro execution (there is no need
to specify any macro settings). All the settings (of dialog based functions)
are specified during the creation of the macro. Macros do not support
correlation functions. Any and all other functionality is supported by
SignaPoint’s macros.
Macros are not designed to work with signals in the frequency domain - such as
signals produced by the Power Spectrum and Power Spectral Density - PSD
(moving window) functions. The sequence of functions in the macro is
executed as defined during the macro creation process. Please note - if the
result of the previous operation is a data/text value (for example ‘Min’) and
the next operation in the macro sequence requires a data vector (signal) as an
input – an error message will be generated. The same applies if two
operations producing data/text value results are set consecutively.
Myosotic SignaPoint also allows macro results to be exported to the machine's
clipboard and then automatically pasted into other productivity applications
such as Word, Excel, etc.

Audio Functionality
Myosotic SignaPoint offers the ability to playback any EMG signal as an audio
signal provided that the correct frequency is selected when opening the
signal. For example if the EMG signal has been recorded at a frequency
of 8kHz, then the same frequency needs to be specified when opening the signal
in order to optimize playback. Once the signal is open and selected, the Audio
playback functionality will play the portion of the signal between the two
cursors. The signal playback may be paused, stopped or resumed by the
corresponding commands/icons in SignaPoint's Audio control panel. The
volume of playback may also be adjusted.
SignaPoint allows to measure the max/min value in frequency domain resulting
signal. That is usually helpful when most significant frequency needs to be
determined. Min/max measurement is also introduced for predefined signals in
frequency domain. That, on the other hand, allows to measure local maximum and
minimums. For example that might help establishing harmonics into the spectrum
of the signal. Also, part of the PSD signals' properties are values of Mean
and Median frequencies. Right click on produced PSD signal and select
"Properties" from the menu. The values of Mean/Medium frequencies of this PSD
representation are listed at the end of the list.

Technical Characteristics
Myosotic SignaPoint is optimized to analyze biological signals. The Workspace
displays the signal duration in seconds along the X-axis and the signal
amplitude along the Y-axis. Depending on the scan frequency chosen for the
analysis, the signal will cover a different time duration on the Workspace and
will stretch differently along the X-axis. There is no upper time limit of how
long the analyzed signal may be or how many signals may be displayed and
analyzed at the same time. When multiple signals are displayed Myosotic
SignaPoint will automatically adjust the Workspace to fit the largest signal
in the group. There is also no upper limit to how many Workspace tabs are open
at the same time.
Myosotic SignaPoint utilizes two cursors (red cursor and blue cursor) for
signal analysis; both cursors may move to any area of the Workspace and may be
attached to any individual signal in the open ASCII file. Myosotic SignaPoint
easily recognizes any signal in an ASCII format once the proper delimiter for
the data is chosen (comma, semicolon, space, tab, or other). After opening the
ASCII file SignaPoint lists all signals in the given file on the right-hand
side of the Workspace. Myosotic SignaPoint then allows to select, display,
hide, analyze, remove, stack, overlay and compare individual or multiple
signals. Any area of the Workspace is accessible by switching from Cursor Mode
to Scroll Mode. The Scroll mode serves as a vertical and a horizontal scroll
bar to go to any part of the Workspace without limitations. In addition to
accessing any part of the Workspace,
SignaPoint features a tiered Zoom Mode; zooming - out resets the scale of the
Workspace to its original proportions. Signals may be stacked or overlaid by
turning the Stack Mode on and off. Once the proper signals analysis and
selection has been completed SignaPoint may save the result as a separate
ASCII file.
Myosotic SignaPoint presents a clean and inviting user interface to go with
its richness of features. The measurement panels "Red Cursor", "Blue Cursor",
"Delta X/Y", and "Immediate Signal Analysis (ISA)" are always visible below
the Workspace and update in real time. The two cursor panels display
information about the X and Y coordinates of each cursor as well as the name
of the active signal to which the cursors are attached. Delta X/Y dynamically
calculates the difference between the coordinates of the two cursors. Lastly,
the Immediate Signal Analysis (ISA) panel calculates in real time the Area and
RMS functions of the signal as defined by the positions of the two cursors.
The ISA real-time calculation may be activated and deactivated. ISA is not
applicable when the two cursors are attached to different signals.
In addition, Myosotic SignaPoint offers some of the most robust yet
approachable biological analysis portfolio in the market. SignaPoint supports
the following 22 signal analysis functions: Minimum, Maximum, Mean, Moment,
Median, Standard Deviation, Variance, RMS, Zero-Crossing, Pathway, Area,
Integral, Difference, Rectification, Normalization, Subset, Polynomial Fit,
IIR Filter, Scale, Power Spectrum, Correlation Signal, and Correlation
Coefficient.

Operation Modes
Myosotic SignaPoint works in four primary operation modes: Cursor Mode, Scroll
Mode, Zoom Mode, and Stack Mode. Cursor mode is used to move the Blue
and Red Cursors in the Workspace. Scroll mode is used as a vertical and
a horizontal scroll bar to access any part of the Workspace without
limitations. Zoom mode is divided in two sub-modes: Zoom In and Reset.
Zoom In is used to zoom-in on any portion of the signal(s) or any area of the
Workspace. Restore resets the Workspace back to its default size. Once Zoom
mode is activated the cursors cannot move. Cursor mode must be activated in
order for the cursors to move again. Stack mode determines if the
displayed multiple signals are overlaid or stacked in the Workspace.

Cursor Movement and Management
Myosotic SignaPoint supports signal analysis with two cursors. The two cursors
are designated as Red and Blue. The two cursors may be attached to any of the
signals in the analyzed ASCII file(s). If the cursor(s) are attached to a
signal that isn't visible that signal will be displayed immediately.
The X and Y coordinates of each cursor as well as the name of the active
signal to which the cursors are attached are displayed in the measurement
panels below the Workspace. The Delta X/Y measurement panel dynamically
calculates the difference between the coordinates of the two cursors. Lastly,
the Immediate Signal Analysis (ISA) panel calculates in real-time the Area and
RMS functions of the signal as defined by the positions of the two cursors.
The ISA real-time calculation may be activated and deactivated at the
preference of the user. The ISA function is not applicable when the two
cursors are attached to different signals. Drag and drop either cursor by
pressing the left mouse button in order to move the cursor along the signal in
the Workspace. The Cursor Mode must be active in order for the cursors to
move.

Signal Analysis - Time Based
Myosotic SignaPoint integrates scientifically precise time measurement onto
its X-axis. The X-axis measures the time of the signal in seconds from
beginning to end. The time positions of both cursors and the delta between
them are displayed in the measurement panels below the Workspace. All
time-based data in Myosotic SignaPoint is calculated and displayed in
real-time as the cursors move along the selected signal(s).
