QGtkStyle error

[chaitu]

Hi

After installing neuronvisio and it's dependencies, I tried to execute
using ipython interface. I typed ipython and then I gave the following
command. As you can see QGtkStyle is unable to detect the current GTK
+them. What does that mean? How can I solve it?

In [1]: from neuronvisio.controls import Controls

QGtkStyle was unable to detect the current GTK+ theme.

Hello,

I think it's related to GTK and Qt interaction.

See if the suggestion here will help you:

Hi Michele,

Though I tried your suggestion, I could not solve the issue. Leaving
that, I tried to load model from the neuronvisio gui mode. After I
choose a model from ModelDB Explorer tab and then after clicking on
load model, I get the following error:

In [2]: from neuron import h

In [3]: controls=Controls()

In [4]: INFO neuronvisio.modeldb.ModelDB 117 Downloading model for

Why isn't that I could load a model from ModelDB?

hi,

the problem is that model doesn't use the classic mod files, but
actually stores the mod file into `mods` directory
I've opened an issue to track this problem:
https://github.com/mattions/neuronvisio/issues/35

In the meantime, what you could do is to:

cd Models/140471/mods/
# compile the mods files
nrnivmodl
# go back
cd ..

then load the model with neuronvisio:

import neuron
neuron.load_mechanisms('mods')
from neuron import h
from neuronvisio.controls import Controls
controls = Controls() # starting the GUI
h.load_file('mosinit.hoc')

HIH,
Michele.

Hi Michele,

I followed the same instructions but when clicking on plot 3D graph,
the software crashes. Please see below:

Which version of Mayavi do you have?

you need 3.6.x with 0.7.3
