[Chimera-users] Regarding saving image in chimera nogui

[NAGARAJAN]

Hi,

  I just tried these commands

from chimera import runCommand
runCommand("open 2trx.pdb")
runCommand("color red")
runCommand("surf")
png_name = "str.png"
runCommand("copy file " + png_name)


but getting error like "Need graphics to save images (or use headless Linux
version)"

Thank you
