Cristoph -
Which version of pmemd? Have you tried the inputs with sander 7 or sander
8, just a short run to see if it works? If you would like me to take a more
detailed look, please put the prmtop/inpcrd/mdin and additional redirections
in a tarball and mail it directly to me (at rduke.email.unc.edu) and I will
look at it, and if there is a deficiency in pmemd, patch it and send you the
patch. The story on these more complicated input modes is that starting
from the first pmemd releases, I made the namelist reading code more
reliable by rewinding after every namelist read, thus making namelist
reading position independent. Now, I know that these two types of
restraints work alone, but I am not sure whether I have ever been asked if
they work together. Anyway, I will be glad to look at it, but because we
don't have this sort of test case, it would be helpful if you send your
input.
Regards - Bob Duke
