navis.read_rda

navis.read_rda(f, combine=True, neurons_only=True, **kwargs)

Read objects from nat R data (.rda) file.

Currently supports parsing neurons, dotprops and mesh3d. Note that this is rather slow and I do not recommend doing this for large collections of neurons. For large scale conversion I recommend using the R interface (navis.interfaces.r, see online tutorials) via rpy2.

Parameters:

• f (str) – Filepath.

• combined (bool) – What to do if there are multiple neuronlists contained in the RDA files. By default, we will combine them into a single NeuronList but you can also choose to keep them as separate neuronlists.

• neurons_only (bool) – Whether to only parse and return neurons and dotprops found in the RDA file.

• **kwargs – Keyword arguments passed to the construction of Tree/MeshNeuron/Dotprops. You can use this to e.g. set meta data.

Return type:

NeuronList

Returns:

• navis.NeuronList – If combine=True and neurons_only=True returns a single NeuronList with the parsed neurons.

• dict – If combine=False or neurons_only=False returns a dictionary with the original R object name as key and the parsed object as value.
