Hello Prof Simmerling
I think I messed up the restraints
So my protein has 284 C-alphas, 284 carbonyl carbons, 284 backbone amide nitrogen atoms, 12 atoms in my isopropanol, 6 atoms in NME and 6 atoms in ACE aps
SO my total atoms restrained should be 284+284+284+12+6+6= 876
I m getting 853 restrained only..
Not sure what and where is the error?
Any suggestions will be super useful.
Thank you all.

Thanks Prof Simmerling,
Actually I m manually checking out the output file to see if that works
This is what I found!
Let me cross check to see if I have all atoms considered or not
5. REFERENCE ATOM COORDINATES
defa
Mask :1-2,3-286.CA,C,N,287; matches 853 atoms

that seems close to what you have in the mask (which is quite different
from the original one). My only concern is that the "N,287" part doesn't
look like it would work properly.
