Hi there,
I did a cognitive task and contrasted active vs. rest (192 Vol). Despite equal
settings for each subject in the FEAT 1st level analysis, I get an inconclusive
“over”-activation all over the brain in my z-stats in a few persons (one cluster
with 20.000 voxels; Z-threshold = 3.1; p=0.01; including FILM). Therefore, I tried
MELODIC to check whether there are components matching my expectations in
these subjects– I didn’t identify any. But, in an SPM analysis expected activation
was detected.
Any ideas?
Thanks,
Marisa
