Hi L.K.
there exist a quick start guide in the graphics window after you opened CAT12:
Quick start guide
VBM data
• Segment data using defaults (for longitudinal data use longitudinal pipeline)
• Check data quality using sample homogeneity for VBM data
• Smooth data (suggested starting value 8mm)
• Estimate total intracranial volume (TIV) in order to correct for different head size and volume
• Build 2nd-level model: Use "Full factorial" for cross-sectional data and "Flexible factorial" for longitudinal data and use TIV as covariate and select threshold masking with an absolute value of 0.1.
• Estimate model
• Optionally transform and threshold SPM-maps to (log-scaled) p-maps or correlation maps
• Optionally overlay selected slices
Additional surface data
• Segment data and additionally select "Surface and thickness estimation" in "Writing options"
• Check data quality using sample homogeneity for surface data
• Optionally extract additional surface parameters (e.g. suclus depth, gyrification index, cortical complexity)
• Resample and smooth surface data (suggested starting value 15mm)
• Build 2nd-level model model: Use "Full factorial" for cross-sectional data and "Flexible factorial" for longitudinal data
• Estimate surface model
Here you can find the mandatory step before stat. analysis:
Resample and smooth surface data (suggested starting value 15mm)
You can also check the updated CAT12 manual that is still in progress (pp. 28):
