Re: Installation problem Neuron
Thank you very much. I'll forward this to my colleagues who try to build it - I presume they still have the old source code and did not update it. Kind Regards, SG stephanmg: that post is more than half a year old. Chances are that the "library deprecated out of existence" issue has been r...

Re: Installation problem Neuron
Greetings! Will it be necessary to apply the patch you posted below to the source? Or will be the --with-readline=no option enough to get rid of the error Symbol not found: _rl_event_hook ? Kind Regards, SG If installing from sources, use the configure option --with-readline=no Also a library I used...

Start NEURON and load MOD files
Dear Users, I've come up with a question: I need to start NEURON from let's say the directory /foo/bar/ but i have my mod files in /ext/dir/ - how would i load the mod files? Please note, I'm using ivocmain for initializing NEURON in a custom cpp project. Best regards and thanks in advance, Stephan

HOC grammar
Dear NEURON users,
it's been a while when i asked my last question here, now I'm back with some small question:
For the .hoc files there must be available a parser in NEURON.
I'm wondering where I could fine a grammar for this parser (probably (E)BNF would be great).
Best regards,
Stephan

Re: use a hoc statement to "load" a compiled mechanism?
Hey, i just want to let you know some issue, maybe you can help out again dear users. If i'm compiling my NEURON from the hg repository as indicated above dynamically, everything fine. That is, i compile a mod file and then i can load it. If i'm compiling my NEURON from the hg repository instead as ...

Re: Possible precision problem
Dear Ted, that's interesting. I'm using in my C code the expression hoc_valid_stmt("a_bla = 0.123456789", 0); Then, if i retrieve it with: double hoc_ac_; hoc_valid_stmt("hoc_ac_ = a_bla"); I receive again lower precision, i. e. 0.123456 for example. Is this to be expected? Thank...

Re: Possible precision problem
Could it be related to this issue, maybe? => http . . . 2. Refuse to accept biological reality. If some parameter really must be specified to > 5-6 place precision, do that assignment in hoc or Python. Or you could insert a statement like a = 0.123456789 in the NMODL code's INITIAL block. This &quo...

Possible precision problem
Dear NEURON users, we're facing a strange problem: The precision of a variable we retrieve from a .hoc file is different from a .modl file, i. e.: let's consider variable foo with value 0.123456789, retrieving it from hoc we receive the full length, i. e. 0.123456789, whereas when the variable foo i...

Re: Import SWC file from NeuroMorpho -> Export as HOC file
Thanks,
to understand it fully, this means, that, if I would add by pt3dadd() points to a section, i implicit define an order of the points along the section, right?

Re: Import SWC file from NeuroMorpho -> Export as HOC file
Hi Stephan, check out the part of the NEURON documentation about n3d() , x3d(i), y3D(i) and z3d(i)... sounds like that's what you're looking for. These functions return the x/y/z coordinate of the ith point along the currently accessed section - so x=0 would be i=0, and x=1 would be i=n3d()-1. chee...
