Adding a model to OPTIM

Adding a potential into the optim TS sampling program requires at least coordinates, energies and gradients. Hessian can also be used in some of the algorithms.

The program must know the number of atoms of the system at the onset to allocate the correct amount of memory. This is a list of the minimum number of routines you may need to change.

1. getparms.f starts the program opens input file odata, set NATOMS

1.5 optim.f calls keyword

2. key.f90 module for keywords

3. keywords.f reads odata and intilizes energy functions

4. fetchz.f read structure for CONNECT runs calls pertable

5. pertable.f add model ID e.g (AM ATSYM) to symbol table, assigns atomic mass

6. potential.f Main interface between OPTIM and external potential

7. finailio.f output

7.5.i geopt.f min.data.info files for pathsample 7.5.ii connect.f path.info files for pathsample
