		s_fparams *	params,
		s_pdb *	pdb_w_lig
	)

## FUNCTION: pockets search_pocket

## SPECIFICATION: This function will call all functions needed for the pocket finding algorith and will return the list of pockets found on the protein.

## PARAMETRES: @ s_pdb *pdb : The pdb data of the protein to handle. @ s_fparams : Parameters of the algorithm

## RETURN: A chained list of pockets found, sorted according to the current critera (the default is a scoring function)
