Thanks Ted, that means I don't have to change things in the code I wrote after all. I do remember reading, although not from the documentation itself, about distance tracing a straight line distance. Perhaps what I read was worded poorly or I just misinterpreted it, but next time I will make sure do...

trace distance along dendrite

Hi all,

I'm aware that the distance function returns the straight line distance between two points, but are there any functions built into neuron that would allow me to trace and return the distance along a dendrite?

Thanks

NetStim seeding question

Hi, I'm having trouble telling NetStim to reseed, by that I mean I set the noise value of a NetStim object to 1, so that the process should behave like a poisson process, but the output is not random. Please consider the following code: load_file("scneuron.hoc") syn_num = 10 run_time = 100...

How to connect ARTIFICIAL_CELL with real cell

Hi, I have a morphologically accurate cell which I've imported into neuron and I'd like to study the effects of synaptic noise on the cell. I need 1000 synapses on the cell and since using 1000 pre-synpatic cells as the source is very wasteful, I decided to make the source of the synapse a ARTIFICIA...

nrn6.0 mpi compiling problem

I've been trying to compile nrn-6.0 with mpi, and I've read the other thread about the issue. But the problem I encountered is a little different. ./configure --prefix=`pwd` --with-mpi MPICXX=/usr/bin/mpic++ MPICC=/usr/bin/mpicc works fine, but when I run make, the following error occurs: mkdir .lib...

Also tried what Michael suggested on the alpha version and got the same error as above. I really don't think it's anything wrong with my system, but rather something in the code.

Thanks, it worked, although the header file calls for other header files in the gnu folder, which I just copied over. Hmm I started to install this on a different machine today with the same method above and I got some what of the same make error output. Please advise. -DUSEBBS=1 -g -O2 -MT nrnpyth...

Compling Problem

Hi, I've been trying to compile the lastest version of nrn with the --with-nrnpython option. I've used both the lastest code as well as those of the standard distribution, and I also have the lastest version of python. ./configure runs fine, but when I run make, I always get the same following error...

thanks for the pointer Michael, but it still doesn't really address the issue of adding an varying value to m at every time step.

introduce a specific type of noise

I would like to introduce a very specific type of noise to one of my channels. From the code below, I essentially need to add the variable 'dpz' to 'm' at very time step. I thought the code would work, but it doesn't. Please advise. NEURON { SUFFIX nap_ch USEION na READ ena WRITE ina RANGE gnabar, g...
