Re: Parallelizing sections within a single cell in python without using GUI

@ted, is there some documentation or an example of how to implement multithreaded simulation without the NEURON GUI?

Single cell in parallel

I have a single cell model with 2500 or so compartments that I would like to speed up. It is implemented using BMTK's bionet, which runs NEURON on the back end. I was reading some older posts and understand it's possible to parallelize a single cell, but that development time is substantial. Is that...

Allen Institute Brain Modeling Tool Kit (BMTK) + Gap Junctions

Hey all, I have been contributing to BMTK (https://github.com/alleninstitute/bmtk), which uses NEURON to model biophysical neural networks. I talked briefly with Ted at SfN about this issue I've been having implementing gap junctions so thought I would formalize that here to see if anyone can help. ...

Re: Errors importing neuron

Well I tried your installation commands and it worked! I'm not sure if installing in /oasis/scratch/ instead of $HOME was the cure or something else. Thanks so much!

Re: Errors importing neuron

I don't think the Anaconda installation is available to others, it is just in my home directory. It is the install available here (I just accepted all the defaults): wget https://repo.anaconda.com/archive/Anaconda2-2018.12-Linux-x86_64.sh bash Anaconda2-2018.12-Linux-x86_64.sh Here's this: $ ldd /ho...

Re: Errors importing neuron

The .so file in /home/latimerb/utils/nrn/lib/python/neuron/ is hoc.so. Yes, which python is anaconda and yes pwd was /home/latimerb/utils/nrn $ which python ~/anaconda2/bin/python In config.status, it says: S["NRNPYTHON_LIBS"]="-lnrnpython -L/home/latimerb/anaconda2/lib -lpython2.7 -l...

Re: Errors importing neuron

The file in <prefix>lib/python/neuron is called hoc.so. Sorry, I pasted the wrong error using a different configuration. This is the error when I do the config like this: $ ./configure --prefix=`pwd` --without-iv --with-nrnpython=`which python` --with-paranrn $ make $ make install $ export PYTHONPAT...

Re: Errors importing neuron

As I progressed I realized it would be easier to just download Anaconda 2.7 to my home directory and use this as my python distribution since it automatically installs other packages I need. So I deleted everything and installed Anaconda 2.7 (https://repo.anaconda.com/archive/Anaconda2-2018.12-Linux...

Re: Errors importing neuron

Using Python 2.7 (module load python) seems to have fixed the issue. Now I don't need to use any extra configuration parameters. Here are the installation commands for (mostly my own) future reference: module load python mkdir utils cd utils wget https://neuron.yale.edu/ftp/neuron/versions/v7.6/7.6....

Re: Errors importing neuron

Thanks Michael. I tried your suggestions but still face the same issue. Here are the commands I used for installation: wget https://neuron.yale.edu/ftp/neuron/versions/v7.6/7.6.5/nrn-7.6.5.tar.gz tar xzf nrn-7.6.5.tar.gz rm nrn-7.6.5.tar.gz mv nrn-7.6 nrn cd nrn ./configure --prefix=`pwd` --without-...

Errors importing neuron

Hi all, I have installed NEURON + Python on many different systems but for some reason am hitting a wall while trying to do "import neuron" on the Comet supercomputer (CentOS 6.10). I followed the instructions at https://neuron.yale.edu/neuron/download/compile_linux and am downloading NEUR...

Re: Optimizing single cells programmatically

Hi Ted, I believe you may be right.. I had assumed they were using the GUI because they have multiple .ses files here: https://github.com/AllenInstitute/biophys_optimize/tree/master/biophys_optimize/passive But upon closer inspection, it looks like they do create some reference to h.MulRunFitter() h...

Optimizing single cells programmatically

Hi all, I'm trying to adopt the Allen Institute's single-cell model creation workflow: https://www.nature.com/articles/s41467-017-02718-3 However, during the "passive fitting" stage of the process (i.e. determining the optimal capacitance and leak conductance for the model), they use NEURO...
