(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. |
