Dear FSL experts,
I have used MELODIC for PICA analysis on a between&within subject design.
All seems to work great but the resulting EVplot (see attachment) worries
me. Instead of getting a clear peak in the 'dim. explained' i get a funny
line. Also, the eigenvalues drop dramatically after 5 components and do not
show the characteristic curve. As you can see the dataset is rather large
(121 runs of 400 volumes).
Does the attached image look OK or is there something strange going on?
Steven
