Hi all,

I'm working on solid state neb and I've few questions:

1. time step in ssneb is default set at 0.1. I'm wondering is this the time step of translation matrix? What's the physical meaning of it?

2. exts.dat and extsss.dat file are generated by after ssneb calculation, which do not appear in regular neb. Can you please explain each column of the two files?
