Hello all,

I am a new user having problems getting a simple minimization to run. I am
using Amber 6.0 on and SGI Origin 2000 parallel computer. My input is
identical to the example supplied in the Amber 6.0 manual on p. 27.


minimization run
   ntb=1, ntc=2,
   maxcyc=500, ntpr=25,


The minimization will be performed on a simple hexapeptide, but I get the
following error when trying to run sander:

rcf:/vol0/home/bothwell/Indoline> sander -O -i -c ypgdv.crd -p

 -o min1.out -r
namelist read: cannot position within current file
apparent state: unit 5 named
last format: namelist io
Unit 5 is a sequential formatted external file
*** Execution Terminated (170) ***

Any suggestions?
