(Actually the routine was copied from write_xyz and and write_pdb and |
19 |
then modified...) |
20 |
|
21 |
This is a small routine to write a GROMOS96 formatted |
22 |
"position coordinate block" (POSITION) or a |
23 |
"reduced position coordinate block" (POSITIONRED) |
24 |
The former has name information (atom and residue names) while |
25 |
the latter only has coordinates. |
26 |
This version does not support the writing of binary |
27 |
GROMOS files. |
28 |
|
29 |
NOTE 1: the actual formats used in writing out the coordinates |
30 |
do not matter, as GROMOS96 uses free formatted reads. |
31 |
Each line may not be longer than 80 characters. |
32 |
|
33 |
(Note, however, in the POSITION block, the first 24 (twenty four) |
34 |
character on each line are ignored when the line is read in by GROMOS) |
35 |
Comments lines, beginning with hash (#) may occur within a block and are |
36 |
used as delimiters for easier reading. |
37 |
|
38 |
NOTE 2: Many programs specify the units of the coordinates (e.g. Angstrom). |
39 |
GROMOS96 does NOT, as all physical constants, from K_B to EPS are |
40 |
NOT hardwired into the code, but specified by the user. |
41 |
This allows some (mostly Americans) to use GROMOS96 in KCal and |
42 |
Angstrom and the rest of us to use kJoule and nm. |
43 |
It also makes it easy to use reduced units. |
44 |
|
45 |
We get around this by supplying a routine, wr_sco_gr96, which |
46 |
will scale the coordinates by a factor before writing. |
47 |
This routine is then called with the factor set to 1.0 in |
48 |
write_gr96A, or to 0.1 in write_gr96N depending on the users choice. |
49 |
Thus, we always assume that we have read coordinates in Angstrom. |
50 |
*** But now handled by a command line option in new framework. |
