Dear Amber Community,
I’m trying to set up a Lys to Glu mutation where only the atoms including and beyond the delta carbon are in the softcore region. Timerge is complaining that the number of non-softcore atoms is different, but I’ve checked and that is not the case. I tried increasing the tolerance to an insane value (100.0), but that didn’t help either.
I’m following “method 2” in the TI tutorial <
https://ambermd.org/tutorials/advanced/tutorial9/index.html#sidechain_mini>, where I created a lib file for the GLU (named MLU) so that the atom ordering is such that the unmatched atoms come at the end of the residue definition. I’ve attached (via a Dropbox link) the dual topology generated by TLEaP and my ParmEd input.
Can any one please help me figure out what is going wrong?
It’s particularly puzzling to me, because I successfully used timerge to build the reverse Glu to Lys mutation.

Best,
