MyoMED™ Data Acquisition Software

Each row of a protocol file encodes a stimulus parameter, such as frequency, amplitude, pulse-width, and duration. Each column encodes a separate stimulus. When using a protocol file to control the electric field stimulator, experiments such as frequency response curves can be performed with ease.


Chart recorder-like displays eases data inspection. Each force transducer signal is recorded on a single channel. Channels are displayed in familiar strip-chart design. Change the X- and Y- axis scales using simple sliders and selectors. The Calibration Wizard simplifies the process of calibration. Calibrations can be performed by placing known weights on the force transducer using our Calibration Kit. For increased efficiency, users can create Notepad files containing a list of commonly used events. These events can then be copied and pasted directly into the MyoMED™ Event Mark box.

View and analyze the results of your experiments using the powerful MyoViewer data viewer application

.In addition to MyoMED™data acquisition software, MyoMED™ myograph systems come with the MyoViewer application for playing back and reviewing the results of previously recorded experiments. The MyoViewer interface is very similar to the intuitive graphical nature of MyoMED™.

Analyze contraction data using the handy cursors in MyoViewer. Cursors can also be used for defining regions of data to be exported as an ASCII file. ASCII files can be used in spreadsheet programs for further analysis, or in graphics programs for constructing publication-quality figures of representative data. Create hard copy print outs of your data right from MyoViewer. These print outs are great for archival purposes, and they allow quick inspection of the results of an entire experiment. Event marks are indicated by numbered tick marks below the force record, and the event text is listed below the data recording.

Constant Current Stimulation for Electric Field Stimulation

 

Our PHY-150I series stimulator units deliver unprecedented ease of use and flexibility in applications requiring electric field stimulation. Each stimulator provides an isolated output, eliminating the need for an external stimulus isolation unit. This allows investigators to perform completely independent stimulation protocols in each tissue bath. This state-of-the-art stimulator is specially designed to provide a constant current stimulus in a low impedance solution such as physiological saline solution. An isolated monitor output allows the user to view the stimulus waveform using a separate oscilloscope. Each stimulator can be independently controlled via MyoMED software. As opposed to many competitors’ stimulators, PHY-150 stimulators from Catamount contain no confusing knobs or switches to set. All stimulator parameters are set in the user-friendly MyoMED™ software.

Stimulator settings are indicated right next to each channel in the MyoMED™ main window. This allows easy determination of the present stimulator settings.

For the ultimate in flexibility, users can program PHY-153 stimulators to automatically deliver a sequence of stimulations using protocol files to encode the stimuli. A protocol file is a tab-delimited ASCII text file (*.txt) that contains the desired stimulus parameters. Protocol files can be made in any spreadsheet text editor, such as Microsoft® Excel.
