Re: [AMBER] Visualizing NetCDF in VMD - ERROR

Without additional information, helping identifying potential problems will be hard.

If you, like me, are using a mac, there is still no support for NetCDF format in VMD in version vmd 1.9.4a48-Catalina-Rev7. I do not know if this support has been dropped in windows/linux versions as well or if this only affects macOS. If this is the case then one recommendation would be to use some other software, like UCSF Chimera, which supports NetCDF on macOS.

If not, then check the content of the “out” file for errors. There are also likely some useful tools available to check the integrity of trajectory files as well, cpptraj may have some tools, parmed maybe.

Best regards
