program Xyz2irc |
|---|---|
| 2 |
! This programs reads a XYZ file and converts it into distances, |
| 3 |
! valence angle and dihedral angles. |
| 4 |
! It prints them as a function of the irc distance... |
| 5 |
!----------------------------------------------- |
| 6 |
! Input: name of the ROOT file of PAW |
| 7 |
! it also needs a file call list which has the following structure: |
| 8 |
! the first line gives the time when you want to start your analysis |
| 9 |
! one line contains the type of the value you want to follow, it can be |
| 10 |
! b for a Bond distance |
| 11 |
! a for an angle |
| 12 |
! d for a dihedral |
| 13 |
! this descriptor is followed by the number of the atoms involved ! |
| 14 |
! a typical file can be: |
| 15 |
! 3. |
| 16 |
! b 1 2 |
| 17 |
! b 2 3 |
| 18 |
! a 1 2 3 |
| 19 |
!---------------------------------------------- |
| 20 |
! Ouput: A files call Scan.dat |
| 21 |
! wich contains in the first lines the input file (as a reminder) |
| 22 |
! and then for each step the wanted values |
| 23 |
!------------------------------------------------ |
| 24 |
! Second version also reads the energy (as to be written after E= on |
| 25 |
! the comment line) |
| 26 |
!------------------------------------------------ |
| 27 |
! Third version contains a new command: c for Center of Mass |
| 28 |
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! |
| 29 |
! v 3.1 the c command now creates the center of mass... and allows |
| 30 |
! people to do whatever they want with it... |
| 31 |
! Syntax: c NbAt ListAt |
| 32 |
!! |
| 33 |
! v 3.2 |
| 34 |
! Added the p command that gives the oriented angle between two planes |
| 35 |
! Syntax: p At1 At2 At3 At4 At5 At6 |
| 36 |
! At1, At2, At3 define the first plane |
| 37 |
! At4, At5, At6 define the second plane |
| 38 |
! How it works: gives the angles between the normal of the two planes, defined by |
| 39 |
! the cross produc At2-At1 x At2-At3 etc. |
