The second leg of the Scottish Premiership play-off final takes place at Easter Road on Sunday, live on BT Sport with a 3.30pm kick-off.
Terry Butcher’s men hold a 2-0 lead from the first leg at New Douglas Park on Wednesday night thanks to a double from teenage striker Jason Cummings.
Butcher said: "The opposing manager is saying it is not over and I am definitely saying it is not over and the players are saying that too.
"There is still a lot of work to be done and we have seen that Hamilton are a good side. We have to have the same focus and attitude on Sunday."
Accies boss Alex Neil said: "It is difficult now. We have to perform as well as we did but take our chances - that was the biggest difference in the game.
"We lacked a bit of quality in the final third which is unusual for us. I don't think we merited a 2-0 defeat.”
