I totally agree with Nathan. Specifying (unintended, but still... ;o) )
'powandcsd', in particular in combination with a spectro-temporal
reconstruction really blows up your memory requirements. Especially when
(again probably unintended) you are computing csd's for all
channelcombination. I'll leave it up to you to calculate how many bytes are
needed only to represent your output csd-matrix in memory.
-each double precision number requires 8 bytes of memory in matlab
-each complex number consists of two double precision numbers
(numberoftimepoints) can become really big.

i'm not too familiar with the fieldtrip specifications, but:

do you have enough RAM?
this would then not be a real fieldtrip problem, but a rather common
problem generally when using matlab.
