autumn bliss - to chop or not?

I planted some autumn bliss a couple of weeks ago, they looked particularly dead having been in a delivery bag for a week in my downstairs loo, sinful I know!!  Anyhow, I planted them not being very hopeful that they'd do anything other than keel over and die if by some miracle they hadn't already.

Did the scratch test today and the wood is distinctly green under the bark so three cheers for surviving my neglect!  But, the instructions were really quite vague, and so I just put them in, but was I suppose to chop them to ground level to encourage new growth or not?  I've never grown raspberries before and the instructions weren't very clear as the summer and autumn were different but you couldn't really decipher which was which.

Thank you if you answer my probably very tedious question for anyone who actually knows what they are doing :o)

One of them is growing :o))))
