NetCon : how to write the reference to 'source'
Hello, i am building an thrshold-crossing detection using the NetCon Class. On one hand, i have a POINT PROCESS "src", defined in NMODL, that has a state "srcState", which is my source for NetCon On the other hand, i have another POINT PROCESS "trgt", in a NMODL, having...

Matplotlib Backend and segmentation fault
For those who use python and matplotlib for plotting results : Just a note about the setting of the matplotlib backend setting ( http://matplotlib.sourceforge.net/faq/installing_faq.html ). When i used "GTKAgg", most of my models raised "segmentation fault", so i changed to "...

Re: WATCH accuracy
Thanks Ted, i tried your workaround, and it works fine with constant step-size. But, i would like to use variable stepsize, and it seems that the statements in the BREAKPOINT block were not evaluated. For example, this modification in the code has no effect on the results (i.e i have an overshoot): ...

WATCH accuracy
Hello, I am trying to build a threshold-detection mechanism, with a state reinitialization, embedded in a NMODL. after trying several things using at_time() and state_discontinuity(,) without success, I realized that the event-delivery system could help me. For test purposes, i've build a minimal NM...

multiple SOLVE
Hello all, I am wondering what could be the problem using multiple SOLVE statements in the same breakpoint block ... ? How should I do if I want to have a kinetic scheme on one side, and a set of rates equations on the other, such as in : BREAKPOINT { SOLVE kstates METHOD sparse SOLVE states METHOD ...

Re: My first template : nil object is not a SectionList
ok, i've found out : the all sectionList is not visible from the inside of init() procedure. Hence i replaced the templte definition by the following : begintemplate Spine external lambda_f public spine, neck public init create spine, neck proc init() { // topology connect spine(1), neck(0) // geome...

Spine Template
Hello, I am trying to build a "Spine" model that i could instantiate multiple times... Thus i thought using a template (shouldn't I ?) that currently has the form : begintemplate Spine public spine, neck create spine, neck objref all all = new SectionList() neck all.append() spine all.appe...

Re: ImportError instance has no attribute 'message'
Hello, thank you for your fast answer, it actually solved my problem. As a result, here is what i did : Place nrn-7.2.alpha-500.tar.gz in /usr/local/neuron > tar xzf nrn-7.2.alpha-500.tar.gz; mv nrn-7.2 nrn > cd /usr/local/neuron/nrn > ./configure --prefix=`pwd` --without-iv --with-nrnpython > make ...

Hello, I must have misunderstood something about segments. with the following code : import neuron from neuron import h spine = h.Section() spine.L = 10 spine.nseg = 10 for seg in spine.allseg(): print repr(seg.x) The output is the following : 0.0 0.050000000000000003 0.15000000000000002 0.25 0.3499...

Future NEURON courses
Hello everybody,
I was wondering if any courses, or Neuron training sessions took place in Europe at any time ?
If not, could anyone tell me more about the future courses in the US ?
Thanks for your help,
