This plugin reads and writes Amber trajectory files. More information can be found at

Note that this plugin is not used for CHARMM "cartesian coordinate files", which often have the same extension. Use the COR plugin for these crd files.


Unused data
Velocity information is ignored by VMD.

Periodic Box
This format makes no distinction between files that contain periodic box information and those that do not. When opening a crd file, the file type must be explicitly set to either crd or crdbox to ensure that the information is properly read by the plugin.
