The problem is that this line :

HETATM 1562 O HOH 189 48.728 50.544 -16.104

is only 43 characters long, and you're doing $zh= substr $_,48,8; on it. That takes the 48th through to the 55th characters and sticks them in a string. Read the error message with this in mind, and see if you can work it out :)
