Thanks for your message. Unfortunately I hadn't tested saving to .mat after the latest changes and there was a small bug -- I fixed it and pushed to the development branch in github: https://github.com/Neurosim-lab/netpyne/tree/development . It will be included in the next version release, but if yo...

Thanks for your message, Brenyn. Your code looks very good. I'm happy to say that in this case the error was due to a minor typo: for pops 'PN_B', 'PN_C' and 'INT' you used 'cellModel ' (with a space) instead of 'cellModel' -- this change fixes your issues. This is the type of error that will be hig...

This applies only to version 0.7.0. We understand this is a big issue and we will avoid it in the future; however, we are still at a relatively early stage of development and this change was necessary to ensure proper randomization of multiple features. Please also note that all previous versions we...

Aah I know what it can be! You need to have the vecevent.mod file which contains the VecStim mechanism compiled in the folder where you are running the sim. Sorry, in the next version I will modify netpyne so it gives a warning if the mod mechanism is not available.

Works for me using your code, so please check that you are not accidentally using an older version (happens often). You can check the version via sys.version() and can check where the files are located using import netpyne; print netpyne.__file__ In theory, to upgrade you should just need to do pip ...

Version 0.7.0 IMPORTANT NOTE: NO BACKWARD REPRODUCIBILITY -- due to improvements in the random number generators it won't be possible to reproduce results of previous versions that required random values, e.g. random spike streams, connections or cell locations. Also, the 'gauss()' method used in st...

NetPyNE releases will be published in this topic

Sorry Ben, didn't realize that feature was in the development branch. I will release a new netpyne version (0.7.0) today, so you just have to upgrade to that one and it should work.

Hi Ben, Thanks for your kind comments and feedback. To provide a list of predefined spike times as stimuli to the network you can create a population of VecStim and provide the list of spk times directly, e.g.: netParams.popParams['bkg'] = {'cellModel': 'VecStim', 'numCells': 1, 'spkTimes': [1,10,20...

Here are some steps to help debug NetPyNE code (which, as mentioned in previous post, is a declarative language): 1) Run first the file containing the NetParams object (e.g. python netParams.py ). From version 0.7.0 onwards, NetPyNE provides error checking (set cfg.checkErrors=True ), indicating any...

Welcome to the NetPyNE Forum! NetPyNE (Network development Python package for NEURON) is a python package to facilitate the development, parallel simulation and analysis of biological neuronal networks using the NEURON simulator. This forum area is your place to receive support about the NetPyNE too...
