Hi Axel,
Will it be possible for you without costing too much time to write a
similar parser for lammps dump as there is for xyz. If not, is it too steep
a learning curve for someone like me who is not conversant with tcl
scripting to write it on his own? It would require too much time to rerun
all my simulations with xyz as the output format.
Regards
Amit
