Dear pymol users
I read in the tutorial:
Atom Selection Macros
/object-name/segi-identifier/
chain-identifier/resi-identifier/name-identifier
I don't understand segi-identifier
I want to select a atom *ca* in residue *2* in chain *a* in *com.pdb*.
object-name = com.pdb
*segi-identifier = ?*
chain-identifier = a
resi-identifier = 2
name-identifier = ca
when I used select active, /com.pdb/a/2/ca --->
Selector-Error: Invalid Selection Name.
( ( com.pdb ) & s; A & c; 2 & r; CA )
when I used select active, /com/A/2/CA ---> Selector: selection "active"
defined with 0 atoms.
I can't attach com.pdb to this e-mail.
First lines of com.pdb is as follows:
ATOM 1 N GLY A 1 45.630 41.790 34.260 1.00 0.00
ATOM 2 H1 GLY A 1 46.390 41.270 33.830 1.00 0.00
ATOM 3 H2 GLY A 1 45.740 41.840 35.260 1.00 0.00
ATOM 4 H3 GLY A 1 44.740 41.370 34.040 1.00 0.00
ATOM 5 CA GLY A 1 45.580 43.190 33.840 1.00 0.00
ATOM 6 HA1 GLY A 1 46.610 43.520 33.710 1.00 0.00
ATOM 7 HA2 GLY A 1 45.050 43.760 34.610 1.00 0.00
ATOM 8 C GLY A 1 44.660 43.310 32.640 1.00 0.00
ATOM 9 O GLY A 1 43.950 42.320 32.420 1.00 0.00
ATOM 10 N LYS A 2 44.740 44.420 31.910 1.00 0.00
ATOM 11 H LYS A 2 45.260 45.170 32.340 1.00 0.00
ATOM 12 CA LYS A 2 44.070 44.610 30.630 1.00 0.00
ATOM 13 HA LYS A 2 44.200 43.700 30.050 1.00 0.00
ATOM 14 CB LYS A 2 44.820 45.700 29.870 1.00 0.00
ATOM 15 HB1 LYS A 2 44.600 46.580 30.480 1.00 0.00
ATOM 16 HB2 LYS A 2 44.400 45.770 28.870 1.00 0.00
what is *segi-identifier *in com.pdb?
please guide me about that.
best wishes.
