This document is a brief description of the Cell Electrophysiology Simulation Environment (CESE). Visit official CESE website at cese.sourceforge.net to get most recent version of documentation and release notes.
The online documentation is included in CESE distribution. Press F1
or select Help/Contents
in the menu at any time to access information about the current state of a program. Use "What's this" feature to get help on a particular interface element.
All models located in the /bin/models
directory of the distribution and in the /cese-1.4/models
local installation directory will be installed automatically during CESE startup. To install models from another location, use Model/Install Model
command in the main menu.
After the normal application startup you will see certain data in the table and tree in the right part of the main application window.
You can set model parameters values in the table ("Value" column). Click on the parameter you want to change, enter new value, and press <Enter>
. If the new value is valid, it will be updated. You can save current model parameters at any time using File/Save Parameters
command. The saved model parameters can be loaded later using File/Open Parameters
command. To reset model to its initial state use File/New Parameters
.
Below the parameters table is a display tree. Here you can select model parameters that will be displayed as simulation results. You can select more than one variable -- press <Ctrl>
or <Shift>
while selecting variables.
Above the table you can see a combobox where you can switch between the installed models.
After setting models parameters as desired and choosing variables for display you can press Start Simulation
(F5
) button to begin simulations.
To select where to put the results (into the new or top window) use Select new/top window
(rightmost) button on the main tool bar.
When simulation is finished the data will be displayed in the new/top Results View
window.
Each Results View
window contains a data area, 2 axis, and corners ("units" and "ms").
To zoom data in the data area press Ctrl
and while keep pressing drag with a mouse (pressing left mouse button) -- you will see a rectangle representing zooming area. Release a mouse button (still keeping Ctrl
depressed), and changes became effective.
Dragging with a mouse from top left to bottom right will set a Zoom In
mode, whereas dragging in the opposite direction will change it to Zoom Out
mode.
Return to the full scale is simple -- press Ctrl
and double click with a left mouse button. You can also click with a right mouse button and select Full Scale
from the context menu.
To zoom data for one axis only, drag with a mouse in the axis area, not in the main data area. You can also use Ctrl-double-click
or use context menu to return to the full scale.
On a left side of each Results View
window you will find a legend panel (hidden by a split pane). In the Legend Tree
you can select a channel and change its color/visibility. You can also specify comment which will be printed with the data.
Press right mouse button to activate context menu for the data area or axis.
To print results select a Results View
window and choose File/Print Results
command in the main menu. Select File/Print Preview
to get a preview dialog where you can change different page setup options.
To save results into the ASCII, ATF (Axon Text File, recognized by Axon's pClampTM software), NetCDF data files, or PNG image files, select a Results View
window and choose File/Export Results
command in the main menu.
You can specify a command that will control certain model parameter during simulation run.
All signals and records are stored as XML documents and can be opened in any text editor. Simple XML editor is built into the environment, select Record/Record Editor
to invoke.
To use a clamp command, open a record file (Record/Open Record
command in the main menu). The environment will go into the clamp mode, and certain variables will be marked as clamped in the model properties table (based on the information in the record file). Start simulation as usual, using Model/Start Simulation
(F5
).
After you selected a record file, you can test its content by selecting Record/Test Record
command in the main menu.
