None, apart from an up to date web browser.
Pick a cell, e.g. this one
Select 3D Neuron Viewer. This will show a 3D view of the cell in an external window (a Java Applet running CVapp, see below if you have issues). Select in Save as the option to download in NeuroML2 format.
If the 3D Neuron Viewer does not open you may have to change your setting to allow Java Applets to run. See: "The 3D Neuron Viewer does not launch. What can I do?" here.
For Mac you may need to specify where the Java Web Start is located (to run the jnlp file). When it asks which application to open with, navigate to the root directory (not Applications), go to "System" -> "Library" -> "CoreServices" and pick "Java Web Start".
If there is still an issue you can either:
- download the SWC version of the morphology (via Morphology File (Standardized))
- convert the SWC file to NeuroML 2 with a local copy of CVapp, the Java application to visualise SWC files
or
- get a copy of the NeuroML 2 file here.
Get a user account on GitHub: https://github.com/join
Create a new repository (green button on GitHub homepage after you're logged in), e.g. named Test_OSB_NeuroMorpho. Select Initialize this repository with a README
Add the downloaded file(s) to your repository. Select Upload files and choose the *.nml file (or the *.swc file, or both) and add then to the repository
Get an account at http://www.opensourcebrain.org/account/register.
If you have been given an Activation token for joining OSB (which allows you to skip the step of waiting for OSB admins to approve your account) enter it here.
Once your account is approved & you log in, you can enter your GitHub usename (and other details) on your account settings page (click your username on top right & hit Edit)
Go back to the home page and click New project and enter the URL of your repository on GitHub. This can be found by clicking the green button Clone or download on GitHub, it will be of the form https://github.com/MYUSERNAME/Test_OSB_NeuroMorpho.git.
Enter a name for your project and select Create.
On the homepage of your new project there will be a button to Explore model which should find the first *.nml model in your Github repository. If there are many or none (i.e. only SWC) you can also click More and this will list all the files in the repo that OSB recognises.
When the 3D scene loads there will be an option to follow a guided tour of the OSB interface. You can follow this, or close the dialog and open it later by pressing the book icon on the left.
You should see something like the following when the cell is visualised (and Model description pressed):
