Example not working #175

I am trying to run the example codes and getting the following error after the colormap is displayed:

ERROR: In /build/vtk6-YpT4yb/vtk6-6.2.0+dfsg1/Rendering/OpenGL/vtkOpenGLTexture.cxx, line 200 vtkOpenGLTexture (0x6d003f0): No scalar values found for texture input!

Please help me solve this. Thanks.

Please be more specific about "the example codes". There are many examples.

I tried two of them: plot_probabilistic_label.py & plot_parc_values.py Both of them gave the same error.

We also need more information about your system, how you are trying to run the scripts, etc. It's very difficult to diagnose a problem without knowing exactly what is causing it.

I am running it on Ubuntu 16.04: (Linux Workstation 4.4.0-57-generic #78-Ubuntu SMP) Python version: 2.7.12 Freesurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0 Pysurfer version: 0.7 (installed via easy_install also tried with cloning and installing the latest github source.) Mayavi version: 4.4.3 VTK version: 6.2.0 OpenGL version string: 4.5.0 NVIDIA 364.19 octacore CPUs (Intel(R) Xeon(R) CPU E5-1620 v3 @ 3.50GHz + Intel NVIDIA GPU 4GB)

Thanks.

Anyways, I saved the figures in the script before it crashes! I guess this will do as a temporary workaround. Although any help for future would be helpful.

mwaskom commented 7 years ago

I'm confused. Your script successfully plots, is able to save a figure, and then raises an error?

transpersonify commented 7 years ago

It successfully plots, then raises an error and the window shuts down due to the crash. But it saves the figure however.

mwaskom commented 7 years ago

It sounds like the crash is happening during the exit of however you're running the script (python? ipython? spyder? you haven't said) and not being raised by PySurfer itself?

transpersonify commented 7 years ago

The crash was due to spyder and now is taken care of. Thanks. Closing the issue.
