*Dear Prof. Case *

*Thank you *

* 1 RESIDUE" and "MAPPING” are all in upper case.*

*2 the error is present for other atoms referenced in residue "MOL" e.g H29*

*ERROR no map function for H29 MOL :data= 20 ASN HD21 71
MOL H29
15.0*

* 3 the restrain works restraints within the protein *

*I modified the RST file to fit to my hydrogen atoms of interest from the
protein and the organic molecule and it seems it work and the organic
molecule stays restrained. Does it make sense? *

*The RST.dist from within the protein*

*20 ASN HD21 19 GLN HNE1 15.0*

* &rst*

* ixpk= 0, nxpk= 0, iat= 296, 282, r1= 1.30, r2= 1.80, r3=15.00, r4=15.50,*

* rk2=20.0, rk3=20.0, ir6=1, ialtd=0,*

*the RST.dist modified for restrained simulation*

* &end*

*30 ASN HD22 71 MOL H29 15.0*

* &rst*

* ixpk= 0, nxpk= 0, iat= 489,1098, r1= 1.30, r2= 1.80, r3=15.00, r4=15.50,*

* rk2=20.0, rk3=20.0, ir6=1, ialtd=0,*

* *
