Option 2: You can modify your command to open in a specific project by changing the -w to -p. Option 3: You can modify your batch file by replacing the -w to -p. If ever you want to wipe all your Spyder global settings, type: spyder -reset from your Python command prompt. Alternatively, delete the.spyder-py3 folder from your user directory. I know that in Spyder, click Tools, Preferences, Ipython Console, Graphics and under Graphics Backend select “automatic” instead of “inline”. However, this make all the figures to be in new windows. It can be messy when I have a lot of plots. So I want only those 3D plot to be in new windows, but all the other 2D plots remain inline. Hi, I have a question about using a notebook in Spyder. How do I move where the notebook pane is located? I want it to be on the same window as the editor but it stays on the same window as the 'help, variable explorer, plots, files' window. Mainwindow = runspyder(app, options, args) File 'C:UsersagnelDownloadsanaconda3libsite.

These options are accessible from the Preferences command in the File menu, and the meaning of each setting is described here. Any changes made will only take effect once you click the 'OK' button or 'Apply'. Options that affect the general behavior of the IDE. Run only one Instance If set, prevents the IDE from being opened more than. (Spyder maintainer here) A dedicated pane that shows all plots generated in our consoles is already implemented and will be part of our next major version (Spyder 4, to be released in 2019). Here you can find some screenshots of that pane.

Notebook Walkthrough¶

If you have not already done so, download and install the Tellurium notebook front-end for your platform (Windows, Mac, and Linux supported).

Basics¶

The notebook environment allows you to mix Python code, narrative, and exchangeable standards for models and simulations. When you first open the notebook, you will have a single Python cell. You can type Python code into this cell. To run the code:

Press shift+Enter,
Click the play button at the upper right of the cell, or
Choose Cell -> RunAll from the menu.

The output of running the cell will be shown beneath the cell.

Creating Cells¶

You can add new cells by moving your cursor past the last cell in the notebook. You should see a menu with three options: New, Import, and Merge. Choose New to create a new cell. You will see four choices:

New Python Cell
New Markdown Cell (for creating narrative)
New Model Cell (for SBML/Antimony models)
New OMEX Cell (for COMBINE archives)

For now, select NewMarkdownCell. Markdown cells allow you to place formatted text and hyperlinks in your notebook. For a review of Markdown syntax, please see this reference.

Editing a Markdown cell

SBML Cells¶

Unlike vanilla Jupyter, Tellurium allows you embed a human-readable representation of SBML directly in your notebook. To begin, first download the SBML for the represillator circuit from BioModels. Then, in the Tellurium notebook viewer, move your cursor past the last cell in the notebook and select Import -> ImportSBML....

Navigate to the BIOMD0000000012.xml file that you downloaded and select it. A new cell will be created in the notebook with a human-readable representation of this model. The human-readable syntax is called Antimony, and you can find an extensive reference on the syntax here. For now, just change the name of the model from BIOMD0000000012 to repressilator.

Changing the name of the model

Now, run the cell. You should see confirmation that the model was correctly loaded and is available under the variable repressilator in Python.

After the SBML cell, create a Python cell with the following content:

After you run this cell, you should see the following simulation plot:

Simulating the SBML model

The repressilator variable is actually an instance of the RoadRunner simulator. Please see the official documentation for libRoadRunner for an extensive list of methods and options that can be used with RoadRunner.

You can also use ctrl+Space to open the auto-completion menu for a variable defined in a previous cell. This also goes for variables such as repressilator defined in SBML cells.

COMBINE Archive Cells¶

Another name for COMBINE archives is the Open Modeling and EXchange format (OMEX), which shows up in various Tellurium menus and functions. COMBINE archives are containers for various community standards in systems biology. They can contain SBML, SED-ML, CellML, and NeuroML. Tellurium supports importing COMBINE archives containing SBML and SED-ML.

To begin, download this COMBINE archive example (originally from the SED-ML Web Tools). In the Tellurium notebook viewer, move the mouse past the last cell until the Cell Creator Bar appears and choose Import -> ImportCOMBINEarchive(OMEX)....

This archive contains an SBML model and a SED-ML simulation. The simulation has a forcing function (representing external input to the system) in the form of a pulse. After running this cell, you should see the following output:

As a demo of Tellurium’s COMBINE archive editing functionality, we can change the duration of the pulse. Change the following line:

To:

In other words, index<6 was changed to index<10. Run the cell:

Editing the OMEX cell

You can re-export this cell to a COMBINE archive by clicking the diskette icon in the upper right:

Find/Replace in Notebook Cells¶

To search for text in a notebook cell, use ctrl+F. To search for whole-words only, use /bmywordb where myword is the word you want to search for.

To search and replace, use ctrl+shift+R. For example, to replace myvar but not myvar2 (i.e. whole-word search & replace) in the code below, press ctrl+shift+R, enter /bmyvarb/ for the search field and newvar for the replace field. The result is that all instances of myvar are replaced, but not myvar2:

Search & replace demo with whole words

Example Notebooks¶

Tellurium comes with many example notebooks showing how to use its various features. To access these notebooks, use the File -> OpenExampleNotebook menu. Tellurium comes with five example notebooks:

The Quickstart notebook contains the Quickstart example from this documentation, using the SBML cells of the Tellurium notebook viewer.

Exporting to Jupyter¶

Tellurium notebooks can contain special cell types such as the SBML or OMEX cells described above. These notebooks cannot be properly read by Jupyter. However, you can export these notebooks to Jupyter by choosing File -> ExporttoJupyter... from the menu. You will notice that the exported notebooks contain special cell magics such as %%crn and %%omex. To run these notebooks in Jupyter, install the temagics package in addition to tellurium using pip.

Advanced Topics¶

Using Other Jupyter Kernels / Languages¶

A built-in Python 3 kernel is provided with the notebook app. However, there are cases where this is not enough. Tellurium owes its existance in part to great free / open-source projects like nteract. We recommend anyone interest in a general-purpose notebook environment consider nteract instead.

Nevertheless, sometimes using a kernel other than the built-in Python 3 kernel is necessary. Starting with version 2.0.14, Tellurium supports automated discovery of other Jupyter kernels, such as different Python versions and distributions (e.g. Anaconda) and other languages (the Tellurium packages are not available in other languages). The following example shows how to use an R kernel with Tellurium.

First, follow the installation instructions for the IRkernel (see also). These instructions use R 3.3.0. The following procedure for installing the IRkernel works for us:

Make sure the IRkernel is registered:

Start the Tellurium notebook app. Under the Language menu, select FindKernels.... A pop-up with a Scan button should appear. Click the Scan button. The results of the scan show all the kernels available to Tellurium. The built-in Python 3 and Node.js kernels are always available. Additional kernels appear based on installed Jupyter kernels. If you don’t see a Jupyter kernel you want here, make sure you have correctly installed the kernel (each his its own set of instructions). If the kernel still does not show up, make sure it is a true Jupyter kernel. Older IPython-based kernels (i.e. kernels which install under ~/.ipython instead of ~/.jupyter) cannot be discovered by Tellurium.

Displaying the available kernels after a scan

Sometimes the path to a kernel’s executable can be displayed by hovering over the kernel’s name. The R kernel you installed should appear in the list. Click the accept button to cause the Language menu to be updated with the new kernel choices.

Hover over the name of a kernel to display its path

By selecting Language -> R, you can cause the notebook to switch to the IRkernel. All code cells will be interpreted as R (SBML and OMEX cells will not work).

Notebook Troubleshooting¶

Problem: Cannot Load Kernel¶

The notebook viewer ships with a Python3 kernel, which causes problems when trying to open a notebook saved (e.g. by Jupyter) with Python2.

Solution¶

In such a case, simply replace the kernel by choosing Language -> Python3 from the menu.

Problem: Saving the Notebook Takes Forever¶

Solution¶

When highly detailed / numerous plots are present, Plotly is known to slow down notebook saving. In such cases, you can switch to matplotlib instead of Plotly by calling importtelluriumaste;te.setDefaultPlottingEngine('matplotlib') at the beginning of your notebook. When using matplotlib for plotting, the long save times do not occur.

Alternatively, choose Language -> RestartandClearAllCells to save the notebook without output.

IDE Walkthrough¶

If you have not already done so, download and install the Tellurium Spyder IDE front-end for your platform (only for Windows, legacy versions supported Mac).

Basics¶

Tellurium Spyder is based on Spyder IDE, a popular open-source integrated development environment for Python. Tellurium Spyder offers experience akin to MATLAB, allowing you to view, edit, and execute Python scripts through dedicated editor and console windows. Addtionally, Tellurium Spyder comes with various tools to help you code. When you first open Tellurium Spyder, you will be greeted by an editor pane with example script, an IPython console, and a Help pane. You can execute the script in the editor pane directly on the IPython console by:

Pressing the green arrow
Pressing F5
Pressing Run -> Run

The example script contains an oscillation model. When you run the script, a plot will appear in the IPython console as the output.

For more information on how to build and simulate a model, check Quick Start and libRoadRunner Tutorial.

Creating and Running Cells¶

Similar to Jupyter notebook, Spyder IDE allows you to create cells. To create a cell, simply put #%% in the script. Each #%% will signal generation of a new cell. To run a cell, press shift+enter while in focus of a cell. If you want to run only part of a script, you can do it by drag-selecting the part and pressing F9.

Importing Files¶

Tellurium Spyder comes with few plugins to help you import SBML, SED-ML, and COMBINE archives. Under File menu, press OpenSBMLfile to open an SBML file and automatically translate it into Antimony string in a new editor tab. To import SED-ML or COMBINE archive, go to File -> Import. You can import SED-ML or COMBINE archive using either phraSED-ML notation or raw Python output. Tellurium understands phraSED-ML notation.

RateLaw Plugin¶

Tellurium Spyder comes with RateLaw plugin. RateLaw plugin contains a list of various rate laws and allows users to insert rate laws directly to the editor. Simply put, it is a dictionary of rate laws so that you don’t have to memorize it. To use it, go to Tools -> RateLawLibrary. You can then choose a rate law, fill in the parameters if you wish, and press InsertRateLaw.

Spyder Tips¶

Both the editor and console window support tab completion. If you are looking for certain functions under a module or a class, simply press tab.

Spyder IDE also supports various ways to check the documentations. If you wish to know more about a function, press ctrl+i while the cursur is next to the function to pull up the documentation in the Help window or execute help(<function>) in IPython console. You can also use <function>? to know more about the object itself. IPython offers various IPython-specific magic commends. Check it out by running ? without any arguments in the IPython console.

Pulling documentation in the Help window or through IPython console.

Sometimes, IPython console might crash. Sometimes, you might want to restart the console to free up some memory. Yes, these things happen unfortunately. To researt the console, simply press ctrl+. in the console or rightclick->Restartkernel. While doing so, you will notice that you can open another IPython console as well.

Advanced Topics on Tellurium Spyder¶

Running Jupyter Notebook¶

Tellurium Spyder comes with Jupyter Notebook by default. To run it, go to StartMenu -> TelluriumWinpython -> LaunchJupyterNotebook or go to Tellurium Spyder installation directory and run JupyterNotebook.exe.

Running Command Prompt for Tellurium Spyder¶

Sometimes, you might want to run a Windows command prompt with the Python that comes with Tellurium Spyder as the default Python distribution. This can be useful if you wish to install addtional Python packages with more control. To do so, go to StartMenu -> TelluriumWinpython -> WinPythonCommandPrompt or go to Tellurium Spyder installation directory and run WinPythonCommandPrompt.exe.

Running JupyterLab¶

Tellurium Spyder comes with JupyterLab by default. To run it, go to StartMenu -> TelluriumWinpython -> LaunchJupyterLab or go to Tellurium Spyder installation directory and run JupyterLab.exe. For more information on JupyterLab, go to Official JupyterLab Documentation.

Tellurium Spyder Troubleshooting¶

Problem: IPython Console Crashed¶

When this happens, IPython will automatically recover most of the times. If it does not, manually restart the IPython console using ctrl+. or rightclick->Restartkernel.

Problem: Cannot Open Tellruim Spyder¶

When Spyder IDE crashes, it will automatically try to recover on the next execution. However, if this does not happen, manually run the reset script. To do so, go to StartMenu -> TelluriumWinpython -> ResetSpyder or go to Tellurium Spyder installation directory and run Spyderreset.exe. If Spyder still does not open, we suggest you to clean re-install Tellurium Spyder.
