When I wrote that the code would be read without errors after deleting the call to cycmake(), I didn't mean this wouldn't alter the behaviour of your code. Actually, cycmake() seems to be the central part of it. Unfortunately, I had some problems reading your modified code, especially this if-clause...

The error message returned is thus: nrniv: syntax error in C:/address near line 651 I checked in the coding and this is line 651: for ii=1,10 print ii, "\t", cycL.x(ii),"\t", cycdiam.x(ii) The error is upstream in line 358: if(AmL2BmL<5 && BmL2AmL<5>=CUTOFF9 && s...

Re: Custom extracellular plane, Poisson equation and dft..

Hi, I know that one effective way to solve the 2D Poisson equation is by using the spectral methods (i.e. employing the DFT), which is supposed to speed-up enormously the computation.. but I assume it will be extremely tough coding all together with the DFT transform and anti-transform in a *.mod fi...

Hi, I want to make an Iclamp that is not really square but instead it follows a sigmoidal at time "del" until it reaches a steady current and then it follows the same sigmoidal inversely at time "del+dur". So far I can make the first sigmoidal but I can't join it with the downwar...

Re: another compiling error

Hello! Hi! The following error occurs for several mechanisms that I'm trying to implement: "syntax error: Illegal block at line 13: PARAMETERS {". What can I do to fix this error? Use PARAMETER instead of PARAMETERS. The latter is not an NMODL keyword. Also, do you see any other problems w...

Hi, Can anybody help me and can give me a link for a cell archive or something like that. The ModelDB will probably help you: http://senselab.med.yale.edu/senselab/ModelDB/ For instance, you will find a layer 3 aspiny neuron in this model: http://senselab.med.yale.edu/senselab/modeldb/ShowModel.asp?...

Hi, I'm not sure how exactly how/where to add a new source file so that it gets picked up in the build sequence. You can add a C++ file to any directory (at least, it worked with the scopmath directory). Just name it *.cpp so that g++ and C++-specific compiler flags will be used instead of gcc. You ...
