Hi
The actual group-ICA maps are not thresholded - but yes there is a preset
colour overlay threshold applied by default in the papaya viewer.
For the latest (~1000 subjects) PTN release, the volumetric maps were created
within-subject using dual-regression, and are z-stat maps from the
Quick question about the papaya viewer interface associated with the
Group-ICA parcellation used in megatrawl: is the activation threshold
(default is set to 10 to 40) used t-value or z-value?
Thanks,
Jenny Gilbert
