Dear Mike,
I have mended the rst file as you proposed and submitted the jobs into the
queue. I hope it'll turn out well.
Thanks for your advice,
Martin
P.S. What's the future of FEP/TI calculations in AMBER? Is gibbs going to be
replaced by SANDER or yet by another program?

Dear AMBER community,
I run thermodynamic integration in a box of water in a batch series: sander
equilibrate, gibbs perturb, sander equilibrate, gibbs perturb in reverse
direction. The error message is
getting new box info from bottom of inpcrd
It is true I cannot see any box info in the Pert.rst file.
Should I set this? How shall irest and ntx be specified in "reverse" sander
run?
Thanks for your advice.
Best regards,
Martin Lepsik
