To simplify program operation, a standard drop-down menu list has been implemented, as can be seen on the top of the window. The menu provides the following functions:
This menu entry brings up a submenu largely related to file maintenance.
This invokes the aopen command to open a data file for collection. The filename is automatically generated as described above.
This invokes the aclose command to close a currently open data file. Closed data files cannot be re-opened.
This causes the program to update the current command list. Only commands that are registered with the program can be executed from the command line. Normally this command is used only during program development when new commands are added. The gather function is implemented automatically on program start-up and normally is not needed by the user.
Closes any open data file and exits the program to the MATLAB prompt.
This menu brings up a submenu controlling which parameter sets will be edited or saved.
Selects the acquisition parameters for display and command-line editing.
Selects the stimulus parameters for display and command-line editing.
Selects a secondary stimulus parameter set for display and modification by a GUI. Note that this only works for pulse stimuli at present. The GUI is designed to allow rapid modification of pulse trains (for example, used to stimulate afferent fiber systems) delivered on a second DAC channel, and updates the information in the primary protocol.
Selects the configuration parameters for display and command-line editing.
Saves the current acquisition parameters to disk, optionally overwriting or renaming the file.
Saves the current acquisition configuration parameters to disk, optionally overwriting or renaming the file.
Each of the New entries corresponds to the creation of a stimulus template for a different kind of stimulus. Use this when you are making new stimulus sets.
This menu selection brings up a choice of commands relating to protocols, including a dynamically updated list of available protocols in the current StmPar directory.
Saves the current protocol to disk.
Reloads the current list of stimulus protocols from the selected directory and redisplays them in the menu.
This selection brings up a Windows directory browser to change the current stimulus protocol directory. A successful directory selection results in an updated list of protocols found in the new directory. The entry StmPar in the configuration parameter set is also updated to reflect the current choice (however, the configuration is not permanently updated, and must be saved manually if the new selection is to be made permanent).
Below this is a list of the recognized StmPar protocols in the selected directory. You may select one of these protocols from the list, and it will be loaded, recomputed if necessary, and is ready to use.
reads the contents of the macros directory, and updates the drop-down list of available macros. The remainder of the list allows selection of a macro from those a available.
causes the program to execute the current sequence, storing data if a file is open. This is how most parametric data is collected.
initiates collection of data without sequencing, and repeats until the stop button or menu item is selected.
puts the program in scope mode (same as the button).
stops ongoing data acquisition (same as the button).
controls mode switching between voltage and current clamp with Axopatch 200 series amplifiers. This requires reading the telegraphs from the amplifier.
forces a redraw of the screen
A number of new options allow you to change the display scaling.
shows the list of current commands, with a short description of each one (taken from the m-file).
shows the status of several of the control flags (mostly used for debugging).
resets the status of the flags, so that acquisition can run. This was necessary at one point to prevent the acquisition from stopping or failing to start. If the program seems to have stalled, or does not begin collecting data when requested, use this menu item to reset it to a known state.
