Before revision:  APBS has enjoyed widespread adoption throughout the biomedical community and is used in numerous applications involving biomolecular structures. However, visualization of complex biomolecular electrostatic properties can be challenging for two-dimensional graphics systems.
After revision:  APBS has enjoyed widespread adoption throughout the biomedical community . Currently, typical use of the full APBS toolset is completed via the command line followed by visualization using a variety of two-dimensional external molecular visualization software. This process has inherent limitations: visualization of complex biomolecular electrostatic properties can be challenging for two-dimensional graphics systems.
