Dear all AMBER users,
I have a problem when I tried to use sander.LES (with amber8). Here are the
procedures I used it:
First, I minimized my non-LES system, and heated it up from 0K to 300K. Then
I used 'addles' to prepare the inputs for the LES. When I used 'addles', I
had the error about exceeding the compilation limit, and therefore I
modified the SIZE.h file and recompile addles. Then everything was OK when I
run 'addles' again. And this is the input for addles:
#######################################################
file rprm name=(LES_ini.prmtop) read
file rcvb name=(heat.rst) read
file wprm name=(LES.prmtop) wovr
file wcrd name=(LES.crd) wovr
action
omas
spac numc=1000 pick #mon 792 792 done
*EOD
######################################################
And I run molecular dynamics using LES, this is the input file (md1.in):
########################################################
LES_md1
&cntrl
imin = 0, irest = 1, ntx = 7,
ntb = 2, pres0 = 1.0, ntp = 1,
taup = 2.0,
cut = 10, ntr = 0,
ntc = 2, ntf = 2,
tempi = 300.0, temp0 = 300.0,
ntt = 3, gamma_ln = 1.0,
nstlim = 100000, dt = 0.001,
ntpr = 200, ntwx = 200, ntwr = 2000
/

And I run the job using:
$AMBERHOME/exe/sander.LES -O -i LES_md1.in -o LES_md1.out -p LES.prmtop -c
LES.crd -r LES_md1.rst -x LES_md1.mdcrd
And here is the output I got:

#########################################################################
Can anyone please tell me what is the problem here? it said " Exceeded
MAXLES 57536", where 57536 is the total atom number in the LES system.
Howeverm I have changed 'maxnatom=70000' in the SIZE.h file before I
recompile addles. Thank you for all your help in advance!
Best regards,
Kailee
