Dear Amber users,

In order to keep the thickness of membrane bilayers,
I'm using average distance NMR restraints.

I've got the following output

======= the output file ========
           Begin reading energy term weight changes/NMR restraints
 WEIGHT CHANGES:
                         ** No weight changes given **

 RESTRAINTS:
 Requested file redirections:
  DISANG = dist
 Restraints will be read from file: dist
 Here are comments from the DISANG input file:
 # membrane distance restraints

and error message from the job manager

==================
1525-049 The list-directed or NAMELIST READ statement cannot be
completed because the input data did not specify a valid delimited
character string. The program will recover by ignoring the item in
the READ statement.

==============================

As you see, at first time I tried "grnam2='P','P','P','P',....." format.
I've got the same result.
Is there anything wrong in my input files?
