Re: Export PlotShape

and aside from export resolution, how to specify "ShapeStyle" in hoc code which can be done by GUI ?

Re: Export PlotShape

Is there a way to specify the resolution in printfile() ? The default one is pretty coarse :)

import matrix from file

Dear Ted, The traditional way to import matrix data from file is to 1. define a matrix and then 2. scanf the file by specifying the number of rows and cols, e.g. mat = new Matrix(nrow, ncol) mat.scanf(fileobj, nrow, nrow) Is there a way in hoc, which can automatically read in the nrow/ncol informati...

Re: nrngui failed as Py_Initialize exited

site.__file__ prints out
'/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.pyc'

so I tried:
export PYTHONHOME=/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7

nrngui failed as Py_Initialize exited

Dear Ted: I just successfully installed NEURON with Python on the Mac OSX 10.9.4, everything works perfect under Python(2.7.8), but the nrngui doesn't seem to go and produces this error message, I tried different PYTHONHOMEs after examining that site.__file__, still no good. Anything else I shall tr...

Re: Equation behind Function Table

When the value is out of the TABLE range, it evaluates the nearest point.

Re: Equation behind Function Table

thank you Ted, yeah , FUNCTION works. A deeper question: when a FUNCTION_TABLE is provided, e.g. FUNCTION_TABLE var (v(mV)), if the values of voltage v in the provided table range only from -30 to 50, then what happens to NEURON evaluation when the voltage is below -30 ? Does it take the value for -...

Re: Recording changes in Impedance in NEURON (Python)

thank you Ted, it works pure :)

another small question on this topic, when we do:
-> imp.compute(frequency)

some models chose the frequency = 10, what does this frequency exactly mean under the hook ?

Re: Recording changes in Impedance in NEURON (Python)

Dear Ted,

recording impedance using the NEURON impedance class works perfectly. Thank you !

but ... another question, how to do a shape plot of impedance throughout a model ? Like in the "Harnett and Magee 2012 Nature" Fig.3a (right) ?

Re: Questions on import3d and export tools

Dear Ted,

First, it shall be "for ii = 0,n3d()-1",

and second, this still prints out the "relative" points ...

soma 0 0 0 30
soma 30 0 0 20
apical 0 0 0 10
apical 30 0 0 5 (apical 60 0 0 5, wanted)
...

any better solutions ?
