Dear all,
            I have prepared a bilyer in charmm and make psf file in
xplor format. I want to minimise and then equilibrate it in namd. But
the job is aborted. My input is attached here and some of the errors
are given below:
ERROR: Stray PME grid charges detected: 1 sending to 3 for planes 97 98 99
Warning: Bad global exclusion count, possible error!
Warning: Increasing cutoff during minimization may avoid this.
Warning: Bad global dihedral count!
Warning: Stray PME grid charges ignored!

Can you please suggest me what is the solution of it? I read such
problems in namd-mailing list and according to some thread I increase
pmegridsize. But doing this the job is running for few steps more but
aborted finally. Please give me some suggestions.

                                   Thanking You
