2 years ago I'm not able to reproduce the error.
Let's debug together; two questions:
1. Do you see the NEURON GUI while running the script?
2.
Can you try the following test; it should save an image called shape.ps:
```python
from neuron import h, gui
sec = [h.Section(name=f"sec[{i}]") for i in range(3)]
sec[1].connect(sec[0])
sec[2].connect(sec[0])
ps = h.PlotShape()
ps.printfile("shape.ps")
```
`shape.ps` looks like:
Does that work on your machine?As an aside, note that this code uses convert from ImageMagick to convert the ps files to png, and avconv to combine pngs into an mp4. The latter was a fork of ffmpeg that is no longer developed; you'll probably want to use ffmpeg instead, so replace the last line with something like:
os.system('ffmpeg -r 20 -i images/image%04d.png movie.mp4')

Under Linux (GNU/Linux x86_64)
I get the following error when trying to launch
python3 runme2.pyTraceback (most recent call last): File "....../dentategranulevideo/runme2.py", line 133, in <module> savefig() File "....../dentategranulevideo/runme2.py", line 64, in savefig with open(filename) as f: FileNotFoundError: [Errno 2] No such file or directory: 'images/45.00.ps'It is apparent that *.ps files are NOT created by
