To attempt to create the frames, I've used two commands:
1) neato -Tpng frame0100.dot -o frame0100.png 2) neato -Tpng frame0100.dot -n2 -o frame0100.png
In using command 1), I imposed the positions of the nodes by writing them in the form pos="x,y!" where x,y are taken from the final frame, in my case frame1000.
THE ERROR I get is:
Error: gdImageCreate returned NULL. Malloc problem?
which you have described in bug report number 904 probably being due to an integer being larger than 231. I suspect this is true because I also get the message:
neato: allocating a -1244933K PaletteColor GD image
It all makes sense given that at the beginning my network is small and there's a lot of white around it, just like mentioned in report 904.
The issue is that I indeed need it to be this way until I've grown the whole network to its final size in order to see how it grows.
I cannot share the network information without a major hassle since there is information which requieres disclosures I do not approve.
I'd appreciate help. Thanks,
[erg] First, please try updating to a more recent version of Graphviz. Version 2.2 is over 2 years old. Also, in 2.2, it was necessary to use the -s option to indicate the scale factor involved. Without it, the numbers could get large. In more recent versions, the default scale factor is set more sanely, so the -s is not necessary.
