when is channel energy effect chosen?

[messy]

"A good cleric (or a neutral cleric who worships a good deity) channels positive energy and can choose to deal damage to undead creatures or to heal living creatures."

is this choice made when the character is created or each time the ability is used?

You choose each time you use the ability.
