trj_cavity finds protein cavities throughout Molecular Dynamics (MD) simulation trajectories. The program works with files in PDB format, but it also can read/generate GROMACS compatible formats such as XTC.
The same project can be compiled as a GROMACS tool or as a standalone version. Installation instructions are provided in the INSTALL file of the project and in https://sourceforge.net/p/trjcavity/wiki/Home/#ffad
If you need support using this tool (or report bugs), please post...
