This might help, I wanted it just simply to test that both hoc and python routines give the same results!

Hi everybody I created a cell class with Python and wanted to use the Neuron gui, so that I can play around with some parameters. In principle this is an easy job for the current accessed section, but if I want to see other compartments, I have to change the currently accessed section all the time. ...

You should probably test to see whether stim.loc(sec(x)) changes the currently accessed section from { whatever it was previously } to { sec }. No, it does not change the currently accessed section: In my case >>> mycell.soma.push() >>> h.cas().name() >>> '<CA3neuron.Neuron object at 0xb04220c>.som...

This was exactly what I was looking for! Thanks a lot!!!!

I was wondering if is there any method to change easily the location of a point process (like IClamp) without having to create and delete an h.IClamp object in Python everytime we change the section. I am trying to simulate THE SAME current injection in different sections of a cell. def stimulator(s...

Very nice advices! I have changed the Sage notebook as you suggested, and now everything can be viewed online. Thanks again for your nice Parallel Neuron tutorials, without them, I would not have done it!!!!.

Thanks a lot Hines! I was erroneously taking the gid source of the NetCon from the current thread, and this is supposed to be taken from other gid/cell/thread. The toy model works now and to show my gratitude I wrote a mini-guide and uploaded as a Sage notebook with the model and an explanation abou...

Hi everybody and happy new year to all of you! I am trying to create a basic ring network to run in parallel as in Hines & Carnevalle 2007 (see in http://www.neuron.yale.edu/neuron/nrnpubs ) together with the help of Thomas McTavish tutorial on https://nn.med.yale.edu:8000 to implement it in Pyt...

Have you released a NEURON spkg for Sage? To build the Neuron shared Python library in Sage you can: 1.- call the python scritp in /nrn/src/nrnpython/setup.py with the sage interpreter, like: # sage setup.py install 2.- Alternatively, change the Line 8 in the file setup.py. Where you find nrnpython...

Thanks a lot for your advice!!! Ted Don't change from one to the other in the middle of specifying the geometry of a section What a dumb thing from my side! I expected that both geometric methods would interact with each other in a section :P. Actually, the problem arose when I overwrote the geometr...

I am running some dummy tests to create cells with the 3D methods and I realized that the length of a segment changes after running pt3dadd(). Is this normal? For example, if I run this: /* dummy.hoc */ create soma access soma soma.L = 10 soma.diam = 10 // 3-D method (see page 146) soma { pt3dadd(0,...

Hi everybody, for debugging processes, I would like to test if an object passed as argument to a class is indeed a Segment. I though that checking it with isinstance () would be appropriate, but unfortunately this launches an error: here a minimal example: from neuron import h soma = h.Section(name ...

Thanks a lot! I agree with you about the way sometimes the information is hidden there :P. For that reason, I created a common documentation/manual project about NEURON for the people in my lab. Just if anyone else want to have a look, it is here: http://neurohost.org/compneurosci/index.html Best.

Hi everybody, I am planning to install the latest development version of Neuron in my notebook from the mercurial site. I tried this >> hg clone http://www.neuron.yale.edu/hg but it replied: abort: 'http://www.neuron.yale.edu/hg/' does not appear to be an hg repository! Would anybody there be so kin...

Dear Ted, thanks a lot for your fabulous and advices. The basic model started to work nicely and I started the changes to perform more complicated simulation I am particularly thankful for your *hints* since this is something that we cannot get in the books and manuals, and required a more experienc...
