Dear All,
I'm running sander for umbrella sampling. My system has a peptide wit 40
residues and 7000+ water molecules. I'm using distance betrween two atoms as
my reaction coordinate. But when I submit the input file, it will not be
submitted. Instead it gives in following error.
ATTENTION: 0031-606 Unrecognized environment variable, MP_RSH.
1525-090 The NAMELIST READ statement cannot be completed because an

aracter was encountered in a NAMELIST group name or item name. The program
will
recover by discontinuing further processing of the READ statement.

We have regetta 16 processors machine from IBM. I'm submitting job with 8
processors.
My input file for sander is as follows:
Abeta-peptide: 1.8ns of MD
&cntrl
imin = 0, nmropt = 1, irest = 1, ntx = 7,
ntb = 2, pres0 = 1.0, ntp = 1,
taup = 2.0,
cut = 9 , ntr = 0,
ntc = 2, ntf = 2,
tempi = 300.0, temp0 = 300.0,
ntt = 3, gamma_ln = 1.0,

My .RST file is as follows:
# 23 ASP HB2 28 LYS NZ 5.8 6.8 (# comments go here
)
&rst
ixpk= 0, nxpk= 0, iat= 361, -1, r1= 2.30, r2= 5.80, r3= 5.80, r4= 8.67,
rk2=20.0, rk3=20.0, ir6=1, ialtd=0,

&end
The mdout file is not being generated at all. Please help me in this
regard.
Thanks in advance,
