Hi, I am trying to call python function in a class using hoc statements to redefine init block. It was pretty easy using hoc programming, but to do the same, in python, I used this approach. I have a MPI based network and in the prun block, I define def prun(self): if self.rank==0: print 'In the fun...

Thank you very much Ted. I was able to solve the problem by adjusting the q10 parameter in the mod files.

Hi, I have two different neuronal cell types, each with its own v_init and celsius. Is it possible to set these parameters independently? celsius and v_init are global variables. I tried changing mod files by inserting a local variable for celsius but it seems like there is a difference in spike tim...

Hi,

I have sent an email with the cell template.

The template is for a detailed model. Is there a possibility to export cell positions from hdf5 and set it in the model? I have predefined cell positions in hdf5.

Kindly let me know.

Thank you.

Hi, I would like to know how multisplit can be used in NetPyNE. I have a cell template from ModelDB where the multisplit option is provided in a separate file by loading the template. In NetPyNE, I find that import cell function takes template file but how do I specify multisplit? Kindly let me know...

Hello, Here's the script I used to simulate from netpyne import specs, sim # Network parameters netParams = specs.NetParams() # object of class NetParams to store the network parameters netParams.popParams['Izhi03a_pop'] = {'cellType': 'PYR', 'numCells': 100, 'cellModel': 'Izhike'} cellRule = netPar...

Hi, When I use integrate and fire model template in NetPyNE through importing class, and when I try to simulate it, I get an error "Point process not located in a section". This typically happens during association of gid to a pointer i.e., NetCon(pointer, None). However, I used to do the ...

Hi,

I have recently installed netpyne and netpyne UI.

When I start the UI, it says on the browser that "Loading is taking longer than usual...". This message doesn't go at all. It keeps displaying.

Is there any workaround for this?

Thank you.

Hi Ted,

Yes, exactly.

Hi, I have been trying to configure NetStim to fire background noise (poissonian) along with stimulus specific activity from 300 to 350 ms. The background activity frequency is 1 Hz and I want to do it for 100 NetStims. I have tried the noise parameter in NetStim but I couldn't get both background a...

Hi, I have started explore NetPyNE functionalities. I wanted to know if we can use import connectivity data from HDF5 file and use it in NetPyNE. The function 'ConnParams' showed an option of "Explicit list", but I couldn't figure out how we specify the gid of pre and post neurons in this ...

Hi, The problem seems to be with the downloaded files of nrn 7.4 and iv 19. I have used nrn 7.5 and iv 19, which worked without any problem. Is it possible to make a dedicated post for the packages required for installing NEURON for Linux and Windows? Because whenever I run into trouble I had to go ...

Hi, While installing NEURON on a linux system, the make command for interviews is failing (libtool: link: cannot find the library `../../lib/libUnidrawhines.la' or unhandled argument `../../lib/libUnidrawhines.la' Makefile:117: recipe for target 'idraw' failed) As instructed in earlier posts, I went...

Hi, I am sorry for asking this question. I didn't understand the use of pc.gid_connect properly for connecting source and target. Now I could use it to connect neurons. When we run the network as 'python init.py' and as 'mpiexec -n 1 python -mpi init.py', should generate same number of spikes, right...

Hi Ted, Thank you for the reply. Is it possible to place source gids and Target gids on same host? I have a predetermined connection matrix. There is no problem in serial execution. But in parallel, I would have preferred a way where both source and Target gids exist on the same host. Thereby avoidi...
