Dear,
We had properly compile amber 6 under RH 6.1 using pgroup compiler ver
3.1.
We tried to repeat, with sander 6, an energy minimization using NOE
constraints already done with sander 5 for a protein of 73 residues.
We used the following input file for amber 5 and it works fine.
-------------------------------------------------
Cu-ATX1  (RMIN on DIANA files
 &cntrl
 ibelly=0,imin=1,nrun=0,nsnb=10,ntpr=100,
 ntwx=100,ntwe=100,ioutfm=0,ntr=0,maxcyc=6000,
 ncyc=1500,ntmin=1,dx0=0.0001,dxm=1.0,dele=1.0e-07,
 drms=.2,cut=10.,idiel=0, scee=2.0,
 nmropt=1,pencut=0.1, ipnlty=2
 &end
 &wt type='REST', istep1=0,istep2=1,value1=0.,
                  value2=1.0,  &end
 &wt type='END'  &end
DISANG=../noe/noe.in
LISTOUT=POUT
--------------------------------------------------
Before running sander 6 we changed the input file according to the
manual chapter 6.3 of the SANDER module as indicated below.
The program works properly without NOE (nmropt=0), on the contrary if
nmropt=1 the program crashes creating a core file.
The same thing occurred with sander_classic using the first input file.
