Hi
Don't quite understand what you mean by 'should have 180 components':
melodic will estimate a rough ball-park figure of how many components
are estimable relaibly from your data. Looks like melodic thinks that
it doesn't make sense to extract beyond 108 components. Or do you
meant hat the corresponding time courses are of length 108 only, even
though your original data is of length 180? If so, something is wrong,
most likely with the input file you;re feeding into melodic. Check
using fslsize that the input really has as many volumes as you think
it should have.
