.. _0stdrun: .. _standardruntools: Standard Run Tools ------------------ All standard tools are available from the NEURONMainMenu. The fastest way to load these tools is to execute .. code-block:: none load_file("nrngui.hoc") which avoids inefficiencies of the :func:`load_proc` command on mswindows machines. Brief summaries of the menu options are provided below, for more information on select functions see also: .. toctree:: :maxdepth: 1 runctrl.rst family.rst Implementations of the standard tools are in `$NEURONHOME/lib/hoc/*.hoc `_ .. _NEURONMainMenu: NEURON Main Menu ~~~~~~~~~~~~~~~~ Main menu for standard control, graphing, menu generation. To pop up the panel execute: .. code-block:: none load_file("nrngui.hoc") Serious users should peruse the init and run procedures. The run chain that eventually calls :func:`fadvance` is .. code-block:: none run continuerun step advance fadvance There is often reason to substitute a new step or advance procedure to do intermediate calculations on the fly. Sometimes it is useful to replace the init() procedure. If so make sure you don't take away functionality which is already there. See `$NEURONHOME/lib/hoc/stdrun.hoc `_ for the implementations of these procedures. File ==== LoadSession """"""""""" Pop up a File chooser for loading a previously save graphical interface session (default extension .ses) Session files may be loaded several times.

Greater control over exactly which windows are saved is given by the :ref:`GroupManager` and the :ref:`PWM`. .. _workingdir: workingdir """""""""" Pops up a Directory chooser for changing to a specified working directory. If a dll file has not already been loaded and if a :file:`nrnmech.dll` (under mswin) or a :file:`nrnmac.dll` (under macos) exists in the "changed to" directory then the dll file is loaded. recentdir """"""""" A list of the last 10 directories chosen from the :ref:`workingdir` menu item. On the mac and mswin, if a dll file has not been previously loaded and such a file exists in the directory, then it will be loaded. Quit """" Exits NEURON.

ArtificialCell .............. Pops up a tool for constructing artificial network ready cells from PointProcess types containing a NetReceive block that can also act as a :class:`NetCon` source. e.g. see :class:`IntFire1`. .. _networkbuilder: NetworkBuilder """""""""""""" Pops up a new instance of a NetBuild class for specifying cells and their :class:`NetCon` connections. Only network ready cells defined by the :ref:`NetworkCell` tools can be used with this class. Tools ===== Fitting """"""" Parameterized Function ......................

Also can fit the function to data using either the simplex or principal axis methods. The more powerful :ref:`mulfit` is now recommended. .. _runfitter: Run Fitter .......... Starts a :ref:`runfit` tool for optimizing simulation parameters to best fit data. The more powerful :ref:`MulFit` is now recommended. Multiple Run Fitter ................... Starts a :ref:`mulfit` tool for general optimization problems. This combines and extends dramatically the features of the :ref:`funfit` and .. _0stdrun_runcontrol: Run Control """"""""""" Pops up a :ref:`runctrl` panel for controlling simulation runs. .. _variablestepcontrol: Variable Step Control """"""""""""""""""""" Pops up a VariableTimeStep panel for controlling the :class:`CVode` variable time step, variable order method. Usevariabledt ............. CVode is the integration method. See :meth:`CVode.active`. Localvariabledt ............... CVode is the integration method and there is a separate dt for every cell. AbsoluteTolerance ................. The absolute tolerance used by CVode when it is active is given by this value times the specific state scale factor. This latter is normally 1, eg, for voltage, but if the state is normally found in a range <<1 or >>1 the scale factor may be explicitly specified in a model description or in the interpreter. See :meth:`CVode.atol` and :meth:`CVode.atolscale` PointProcesses """""""""""""" Several useful tools for managing PointProcesses See :ref:`mech` for details about built-in point processes. The corresponding :file:`.mod` file must in general be examined in order to understand the particulars about a given point process type.

Pops up a panel for viewing/setting the global temperature variable :data:`celsius` . globalRa ........ Pops up a panel for assigning a uniform value of :data:`Ra` (ohm-cm) to all sections. Ra used to be a global variable but is now a Section variable that can be different in different sections. This sets Ra forall sections equal to the value displayed in the fieldeditor. It used to be displayed in the NEURONMainMenu but that location is now administratively incorrect and error prone for models which manage Ra through the :ref:`CelBild`. Impedance """"""""" Menu of tools which use the :class:`Impedance` class to calculate voltage attenuation as a function of position and frequency Frequency .........

Kinetic Scheme Builder ,,,,,,,,,,,,,,,,,,,,,, Starts a :ref:`KineticBuild` tool for simulating a single channel kinetic scheme Graph ===== For creating common kinds of graphs of functions of time. These graphs are connected to the standard run procedure such that at every step (see :ref:`0stdrun_runcontrol`) the value of the functions are plotted. Currentaxis """"""""""" Plots values vs t-.5dt Suitable for plotting ionic currents (when calculations are :data:`secondorder` correct). Stateaxis """"""""" Plots values vs t+.5dt Suitable for plotting states such as m_hh, n_hh, etc. These plots may be very accurate when :data:`secondorder` = 2. Shapeplot """"""""" Starts a :class:`PlotShape` . A picture of a neuron suitable for specifying time, space, and shape plots.

PhasePlane """""""""" Starts a :class:`Graph` for plotting f(t) vs g(t). When started a dialog box pops up requesting the expression for g(t). As in the PlotWhat browser for graphs you may enter any variable or function, but it should change when the RunControl's InitRun button is pressed. Grapher """"""" Starts a :ref:`Grapher` tool for plotting any expression vs a specified independent variable. Lines are not drawn on this graph in response to a run. However it can be made to control a family of runs. Voltageaxis """"""""""" Plots values vs t. Suitable for plotting voltage and concentrations, especially when calculations are secondorder correct. v(.5) of currently selected section is always plotted but can be explicitly removed with the Delete command in the Graph menu. Vector ====== .. _vector_savetofile: Save to File """""""""""" Menu for saving/retrieving the last Vector selection to a file. eg. from a :ref:`gui_PickVector` as well as other Vector tools. The format of the file is: 1) optional first line with the format .. code-block:: none label:anystring 2) optional line with one number which is the count of points. 3) a tab separated pair of x, y coordinates each line. If there is no "count" line, there must be no empty lines at the end of the file and the last character must be a newline. When the file is saved with this menu item, the label and count are always present in the file. For long files retrieval is much more efficient if the count is present. The implementation of these operations is in `$NEURONHOME/lib/hoc/stdlib.hoc `_ vectors and performing simple manipulations on them. .. seealso:: :data:`hoc_obj_` .. _stdrun_retrievefromfile: RetrievefromFile """""""""""""""" See :ref:`vector_savetofile` GatherValues """""""""""" Starts a :ref:`GatherVec` tool collecting x,y values where x and y come from variables.

Window ====== A list of all the ungrouped windows (except the NEURONMainMenu) and window groups. Windows mapped to the screen are indicated by a checkmark; others are hidden. Windows may be hidden by selecting the :guilabel:`Hide` item on the menubar under the window title. Windows may be hidden or mapped by selecting the item in the ungrouped window list. Selecting a window group will hide or map all the windows in that group. Ungrouped """"""""" A window appears in this list if it is not a member of a window group. All ungrouped windows may be mapped or hidden by selection of the show or hide menu item. .. _groupmanager: GroupManager """""""""""" Window group names appear in this list. Selecting this item pops up a window group manager used for creating, renaming, inserting/deleting windows into the group, and saving a selected group to a session file. The window group manager is a dialog box so it must be closed after use. When a window group name is defined it may be selected in the WindowGroups list. The windows of the group are indicated in the middle list. Selecting items in this list and the ungrouped windows list removes or inserts the window into the group.
