Topic: Compilation of iv-17 on SGI IRIX64 6.5 fails
Replies: 3

I have not seen the strange X and $X prefixes before on the SGI or anywhere else. I'd recommend using the http://www.neuron.yale.edu/ftp/neuron/versions/alpha/iv-17.tar.gz version since it has been slightly updated to compile under gcc-4.0.0 on osx 4 but that seems a longshot for the sgi. If that ma...

I did an experiment to see if one can use pointers to weights and it indeed works. Consider the NEURONDEMO after choosing the Synchronizing Net demo. oc>NetCon[5].weight -0.3 oc>objref pp oc>pp = new Pointer(&NetCon[5].weight) oc>pp.val -0.3 oc>pp.val = -1 oc>NetCon[5].weight -1 oc> Of course the us...

Did you have a previously installed version and overwrote the old sources with the new version? If so there has been a recent upgrade to the sundials integrators that removed and added many files. It may be that you need to do a make clean to get rid of the old .o files before doing a make. If this ...

I should also mention that a PointProcess instance of a ChannelBuilder specification, when "Allow Single Channels" is selected, can be switched between macroscopic current mode and single channel mode by setting the value of Nsingle. When Nsingle has the value of 0 then it is a macroscopic current, ...

Single channel models can only be constructed with NEURONMainMenu/Build/ChannelBuilder/Point There can only be a single gate defined as a kinetic scheme raised to the first power. At that point you can select the Properties/AllowSingleChannels checkbox. For an example, launch the NEURONDEMO and sele...

request for comments

I have a question primarily directed to those who understand quite a bit about Python and a bit about NEURON's conceptual idea of the section. Several months ago, Mike Neubig suggested that NEURON's usefulness would be greatly enhanced if Python could be used as an alternative interpreter. To this p...

Replies: 1

I see that none of the Impedance tools have the ability to save themselves into a session file. And none of them use the proper idiom for properly opting out of the session file, i.e. when the box holding the gui for the object is created one should use VBox.save("") where the argument is an empty s...

Re: Increment used by spinner

There is no way under program control to set the increment/decrement value for default field editors. That would require a new method to the ValueFieldEditor class, see: http://www.neuron.yale.edu/neuron/static/docs/help/neuron/general/classes/vfe.html and/or yet another optional argument to xvalue ...
