Dear Ambers,
I met a wierd probelm with my small molecule with fluorine atom inside.
I used antechamber and parmchk to prepare .prep and .frcmod file for it.
The input file for protein-ligand complex were generated using xleap. when
I run my minimization with the script "min.in", a error message: bad atom
type: f and the job was stopped. Why I didn't get complain about atom type
in xleap?
The content of my min.in:
cat <<eof > mdin
minimize structure
&cntrl
imin = 1, maxcyc = 1500, ncyc = 1000,
igb = 2, saltcon = 0.002, gbsa = 1,
cut = 500,
ntpr = 50, ntx = 1, ntb = 0,
ntr = 1,
&end
keep all atoms frozen
250
RES 669-919
END
END
eof
sander -O -i mdin \
-c AR.crd -p AR.top -ref AR.crd \
-o AR.min.out -r AR.rst
Thank you very much!
aini
