Dear Mr. Case,
We got the AMBER 7 a couple of months ago to our group, and I read the
document 0README which is under the resp directory. (Specifically
/amber7/src/resp) It was described in Mr. Caldwell's email which is part
of this 0README file. I am trying to recalculate the Cornell et al.95
results, but as far as I understood, it is not possible because of the
orientation problem of the molecule at interest.
Best,
