| 18 |  |  | (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. |
