Dear Amber Users,
I am doing FEP calculation for a protein system in an aqueous solution. I
want to mutate some of the residues in the protein. For this I loaded the
protein in xleap , selected all the atoms and through edit selected atoms
from the unit editor menu bar created the spreadsheet editor to edit the
residues of the protein.But strange thing is that in the spread sheet
editor (editor table) I got the lists of atoms of FEW residues but NOT
ALL. I hope this problem is with the large protein system with aqueous
solution. As I removed most of the water molecules from the protein, it is
being possible to edit all the aminoacid residues with all the atoms
in the editor sheet. But I want to edit the protein in presence of all the
water molecules in the protein system.
I mailed this problem in my previous mail and got one reply to do the same
job in LEaP command line. But I am not being able to give the appropriate
command in the LEaP command line for the said problem. So can anybody
please suggest how exactly I have to do this and what commands I have to
follow in the LEaP command line to solve this problem.
Thanks for your suggestions in advance.
regards
B. R. Meher --
