mhines, we're still running into this issue.
Providing --with-readline=no makes neuron compile, but it makes bluepyopt crash during tests (and it's difficult to see what exactly happens).
What would be the effect of disabling readline ?

Hi,

Doesn't without the 'h.', work ?

Okay, I have found the problem when I tried to make an easy-reproducible testcase. It was a (tricky) mistake I made. The following code works: #!/usr/bin/env nrngui -nogui -python import neuron from neuron import * import nrn from nrn import * h('create soma') h('access soma') h.soma.insert("Na...

Mmm, I've found another solution that works: h('objref tempvec, tvec') h.tvec = h.Vector(2) h.tvec.x[0] = 0 h.tvec.x[1] = 1100 h.tempvec = h.Vector(2) h.tempvec.x[0] = 30.0 h.tempvec.x[1] = 32.0 h.tempvec.play(h.axon(0.5)._ref_enax_Na, h.tvec, 1) h.tempvec.play(h.soma(0.5)._ref_enax_Na, h.tvec, 1) N...

I've problems with playing a vector into a variable in python. The following code works: h('objref tempvec, tvec') h('tempvec = new Vector(2)') h('tvec = new Vector(2)') h('tempvec.x[0] = 30') h('tvec.x[0] = 0') h('tempvec.x[1] = 32') h('tvec.x[1] = 1100') h('tempvec.play(&axon.enax_Na(0.5), tve...

Thx,
Sorry that I didn't notice the interpolate function in the documentation.

I have one comment about this, I've been using statements like soma = neuron.h.Section() It's a short way of writing this down, but it's only a pity that in the hoc world this translates into an object with a strange name containing the pointer address of the object. Since I'm still mixing sometimes...

I want to write a function in my python code, that automatically writes every time step all the membrane currents in a segment to a file. I have all the code for this, the only piece I'm missing is a way to automatically find out all the fields that are available in a segment (the _ref_ attributes),...

I'm having exactly the same problem after installing (i.e. compiling from source) it on a new Snow Leopard.

Actually, concerning that DISPLAY issue, I've looked into the neuron source: if (getenv("DISPLAY")) { session = new Session("NEURON", our_argc, our_argv, options, properties); }else{ fprintf(stderr, "Warning: no DISPLAY environment variable.\ \n--No graphics will be displaye...

I've tried replacing the reference with one to ivos, but now I get a new error: "libnrniv.so.0: undefined symbol: nrnpython_reg_real" Btw, the reason why I'm configuring --without-x is because the -nogui option doesn't seem to work when using python. When I run a python script with 'nrniv ...

Hi,
No, not at the moment I think, but when I started using that subversion archive more than a year ago, I think there was. I was just doing 'svn update' to get the new release, didn't realize that you stopped using that archive.

Werner

Okay, have discovered the problem, apparently the subversion archive doesn't contain the latest release, have used the Mercurial repository now. This solves the problem.

Werner

Small addition, it seems to work in Neuron 7 that is compiled from the tarball on the website, but I'm using the latest repository release, downloaded with subversion.

Werner

Hi, Does anybody have any idea why the following code is not working anymore in Neuron 7 (Revision 2227) ? create soma objref vclamp1, v1 v1 = new Vector(1000000) soma { vclamp1 = new SEClamp(.5) v1.play(&vclamp1.amp1,0.02) } tstop = 1000 run() I get the error: NEURON -- VERSION 7.0.0 (2227) 200...
