[gmx-users] pdb2gmx atom not found

[xy21hb]

Dear all,


I am introducing a residue named ABC into AMBER03 force field. I built up the aminoacids.rtp and aminoacids.hdb file,
but when I pdb2gmx, it gives,
"
Atom HB1 not found in rtp database in residue ABC, it looks a bit like HB
"
I am pretty sure I use HB instead of HB1, and there is no atom called HB1 in any of the above-mentioned files.(including .pdb for pdb2gmx)
then I changed my HB to HB1, it gives similar error, 


"
Atom HB11 not found in rtp database in residue ABC, it looks a bit like HB1
"


It seems that pdb2gmx is appending the name with "1".


Anyone knows why that is?


Thanks,


Yao
