Sir,

I understand that I need to change the atom names of MOL in my complex pdb
so that the atom names are equivalent to that in prp.prepin file. But how do
I s do so?
The ordering is different with H's inserted between them.

Like...

In prp.prepin file:

   4 *C1* cc M 3 2 1 1.540 111.208 180.000 -0.129681
   5 H3 ha E 4 3 2 1.070 142.308 -177.898 0.150833
   6 *C2* cd M 4 3 2 1.331 90.646 0.344 -0.129681
   7 H4 ha E 6 4 3 1.070 127.188 -178.398 0.150833
   8 *C3* cd M 6 4 3 1.470 106.080 1.154 -0.119611
   9 *N1* nc M 8 6 4 1.300 112.000 -0.240 0.027748
  10 *C5* cc M 9 8 6 1.393 106.304 0.206 -0.119611
  11 *C4* cf M 10 9 8 1.354 126.020 -179.902 0.164181
  12 *C21 * ca S 11 10 9 1.507 118.141 -179.870 0.470007
  13 *C22 * ca B 12 11 10 1.395 120.992 90.681 -0.396821
  14 C23 ca B 13 12 11 1.372 119.574 179.842 0.105984
  15 N5 na B 14 13 12 1.339 121.297 -0.195 0.060298

In complex pdb:

HETATM 1 *C * MOL 1 -4.017 -15.843 2.209 1.00 -0.10
.035 C
HETATM 2 *C* MOL 1 -4.354 -14.645 2.734 1.00 -0.10
.035 C
HETATM 3 *C* MOL 1 -4.335 -13.691 1.625 1.00 0.20
.070 C
HETATM 4 *N * MOL 1 -3.975 -14.303 0.458 1.00 -0.60
.247 N
HETATM 5 *C* MOL 1 -3.402 -16.640 -0.116 1.00 0.00
.030 C
HETATM 6 *C* MOL 1 -3.793 -15.618 0.781 1.00 0.20
.070 C
HETATM 7 *C* MOL 1 -3.085 -16.472 -1.477 1.00 0.30
.046 C
HETATM 8 *C* MOL 1 -2.761 -17.500 -2.426 1.00 -0.10
.033 C
HETATM 9 N MOL 1 -3.060 -15.282 -2.166 1.00 -0.70 .355
N

So will I change manually to C1,C2,C3,N1,C5,C4,C21,C22, but the next C is
missing in prp.prepin file, then how should I number it?
