Dear all,

I am Steven Huysecom, a biochemistry student currently working on neuron structures. For our project, we need to extract synaptic data on a neuron's structure. We have screened neuron images with the SynapseDetector-tool. Next, we combined both the SWC-output and the synapse data with the combiner tool in Vaa3D. This yields eswc-files. 
We want now to extract both data on the neuron structure and the synapse location from this eswc-file with a self-written python script. The problem is, we do not know how the information about synapses is stored in the eswc files, and how to read them out. Hopefully, you guys can help me. 
Thanks in advance! 

Kind regards, 

Steven Huysecom

a swc file has 7 columns, i.e. order,type, x,y,z,radius, parent

an eswc file has additional columns that are defined to generate further information such as colors of nodes in a neuron structure.

in your case, it seems you only need to read an eswc file just like reading a swc file? i.e. ignoring the additional columns?
