Re: Importing HDF5 data to NetPyNE

Hi, It is possible to specify a custom list of connections -- see connList parameter in connectivity rules. So you can just load the data from the HDF5 file and pass the list of connections in a connectivity rule. The format is just the list of pre and postsynaptic gids. For preConds and postConds y...

Re: Setpointer when defining a synapse

Hi Noemie, Currently, netpyne does not support synapses with pointers. I added a Github issue to add this feature in the future: https://github.com/Neurosim-lab/netpyne/issues/332 You could try creating the pointer "manually" after the network has been instantiated -- but it is not an eleg...

Re: Import json format of morphology to NetPyNE

Hi Javad, Thanks for your question. So the file format is .json but what is the data structure that the morphology is stored in? e.g is it a dictionary of sections with 3d pts, does it follow a similar structure to swc? Perhaps you can share the file to get a better idea. NetPyNE can import morpholo...

Re: Slow speed to save sim results

Hi Stefano, Sorry to hear the saving is taking so long. The independence of num of cores is normal, since data is gathered on the master node and then saved. The similar speed with SSD drives might indicate that what's taking longer could be the internal conversion to Matlab format (prior to saving ...

Re: Field names are restricted to 31 characters

Hi Stefano, I have never encountered this error but yes, it is related to the scipy savemat function, which has a limit of 31 chars per field: https://docs.scipy.org/doc/scipy/reference/generated/scipy.io.savemat.html There seems to be an option to increase it to 64: long_field_names = True hope thi...

Re: Mat file not saved properly in batch functions

Hi Vittorio,

Thanks for pointing this out, the issue was related to a bug in the "scipy" package — see https://github.com/scipy/scipy/issues/3487.

I found a workaround in netpyne and pushed to the GitHub ‘development' branch — it now works ok.

Thanks
Salva

Re: Gap junction support - parallel simulation?

I fixed the bug that was preventing gap junctions to work with multiple cores. It will be released in the next version but you can try it now using the 'development' version of NetPyNE -- see instructions here: http://neurosimlab.org/netpyne/install.html#install-via-pip-development-version let me kn...

Re: Gap junction support - parallel simulation?

Yes, it did originally, but I just tested it and seems some change introduced in a later version has broken mpi support -- I will post a message here once I fix it.

thanks for your message
