=============
I was (badly) unable to find a description of "Amber 6/7 GROUP
format". I found a thread alluding to possible bad compilation of
pmemd. The one I used (intel ifort, mkl) was suggested by Ross Walker

I used it some time ago quite successfully for production MD on a
parallel NUMA-type machine with dual-opteron 875.. This is the first
time I try with restraints on the same machine and compilation.
Thanks for indicating where the format of restraining should be, or
what else. As the procedure of restraining with this large system in a
lipidic membrane is quite long, I would like to carry it with pmemd.
