Do you expect to update the tar.gz package at http://www.neuron.yale.edu/ftp/neuron/v ... 7.4.tar.gz soon?

Many thanks!

Thanks for the quick reply. The fix solved the problem with the example I showed, but if I change the last line to:
the error reappears.

I'm getting an error with NEURON 7.4 for code which worked fine in versions 7.0-7.3. An example: from neuron import h, hclass class SpikeArray(hclass(h.VecStim)): def __init__(self, spike_times=[]): self.spike_times = h.Vector(spike_times) self.play(self.spike_times) stim = SpikeArray([1, 2, 3, 4, 5...

Here is one way to do what you want: import neuron soma = neuron.h.Section() soma.nseg = 10 first_segments = [] first_segments.append(soma.__iter__()) def list_segments(seg): while True: yield seg.next() for first_seg in first_segments: for seg in list_segments(first_seg): print seg.x

I find that the GUI works if launching the Python interpreter via

nrngui -python

but not with plain "python"

(this is on Linux and Darwin, don't know about Windows)

You don't need the CVS version for the example I posted above.
nrnpython was certainly in version 5.8, and I imagine it is in 5.9.

To get the hoc module, you have to run nrniv -python This starts NEURON with the python interpreter (assuming NEURON has been compiled with the --with-nrnpython configure option). You should then be able to >>> import hoc >>> import nrn At the moment, the hoc module only provides one function: execu...

This will become obsolete as the functionality of the python interface increases, but I have created a class HocToPy, with a static method get(), to make getting variables from hoc into python easier: import hoc class HocToPy: """Static class to simplify getting variables from hoc.&qu...

My original idea was that it would raise an Exception if the size of the tuple or list did not match the number of segments. If you would prefer it to fail gracefully, then either the relationship you suggest or some sort of interpolation would be possible. Alternatively, nseg could be automatically...

I like the syntax very much. It actually seems to make more sense than the equivalent hoc syntax, since "x" relates to the section and not to the mechanism variable and so is closer to the object it relates to. What I would not like to see lost is the ability to assign the same value to al...

Alain Destexhe has a demonstration of how to create movies from NEURON here:

(Unix/Linux only, although it would probably work with Mac OS X or Windows with Cygwin).

If I ventured an idea I would suggest that one range variable would be implemented as a method for each "section" object. This class method accepts one argument which may be any float in [0,1], and return the value it found in the closest segment. Unfortunately, this works fine for print ...
