Dear VMD Community,

I'm trying to build a protein-membrane system following the Membrane Proteins Tutorial. However, I keep receiving the error pasted below each time I try to build a POPE membrane with the Membrane Builder plugin using the CHARMM36 topology file (VMD 1.9 MacOS X OpenGL, CUDA (Intel x86)). Could anyone please give me some insight into what is wrong? Or could this be a bug in VMD 1.9? If it helps, I can successfully build a POPC membrane with the plugin using C36 and also a POPE membrane using C27.

Thanks in advance for your help,

Maggie Pruitt
