Cellbuilder hangs the system

[badjoby]

Hi,

Using NEURON -- Release 7.0 (281:80827e3cd201) 2009-01-16
on Ubuntu 8.10 and 9.04

1) start nrngui
2) Build->Cell builder
3) The check boxes are not checkable including Cont Create.
4) Attempt to click on the check boxes 2-3 times cause the system hang.

but If I do the following
1) start nrngui
2) At oc> prompt enter the following

objectvar ocbox__
{
load_file("celbild.hoc", "CellBuild")
}
{ocbox_ = new CellBuild(1)}
{
ocbox_.map("CellBuild[0]", 117, 494, 788.16, 358.08)
}

(from your program)
then Cell builder comes up and the everything including check boxes are fine.

thanks, joby

Did you install with the rpm or did you get the gzipped tar files and compile the source code?
Does neurondemo work?

Hi Ted,
I initially tried the compile and install. Same issue. Then I installed the rpm version. Same issue.
So I guess it is mismatch with my system configuration. What I find puzzling it that why only
invoking Cellbuilder from the GUI have the issue?
thanks, joby

Neurondemo works.

Hi

At the oc> prompt if I use

{ocbox_ = new CellBuild()}

instead of

{ocbox_ = new CellBuild(1)}

I have the same issue.
I find that
nrn70/share/lib/hoc/celbild.hoc
uses the first format as given below

objref tobj
proc makecellbuilder() {
tobj = new CellBuild()
objref tobj
}

Any clues. I am totaly unfamiliar with hoc and Neuron.
thanks, joby

Hi,
I modified part of my nrn/share/nrn/lib/hoc/celbild.hoc
to the following and it seems work so far without hanging..

objref tobj
proc makecellbuilder() {
tobj = new CellBuild(1)
tobj.map("CellBuild[0]", 117, 194, 788.16, 358.08)
objref tobj
}

I am sure this is a kludge. What is the real reason?
thanks, joby

Please go back to the original version before your change and edit
nrn/share/lib/hoc/celbild/celbild1.hoc and replace the fragment in the
proc init()
that reads:

Code: Select all

        if (numarg() == 0) {  
                sprint(tstr,"%s", this)
                vbox.map(tstr)
        }

with

Code: Select all

        if (numarg() == 0) {  
                map()
        }

If that works, let us know and I'll make the change also.
I continue to be uncertain of the reason for the problem.

Hi,
I checked it out and it does not solve the problem :(.
Does CellBuild use the argument 1 anywhere?!
