Dear CAT12 users,
thanks to Guillaume's suggestion from last week about merging surface meshes I have now also implemented this idea in CAT12 which makes statistical analysis hopefully somewhat easier. With CAT12 version > r1200 (http://dbm.neuro.uni-jena.de/cat/) you can now merge both hemispheres if you "Resample & Smooth Surfaces" and the resampled surface is indicated with "mesh" instead of "lh" or "rh". Thus, only one single stat. analysis for both hemispheres is necessary. I have also updated all tools for visualization and also for Threshold-Free Cluster Enhancement (TFCE) which should now deal with merged meshes.
Furthermore, I have implemented some new features in the "Display Surface Results" tool which might of some help:
1. Switching between multiple surface results (selection of up to 24 result maps)
2. Optional overlay of atlas boundaries
3. Use of flatmaps for overlay (thanks to Bjoern Horing from Hamburg for having that great idea)
Finally, the preprocessing pipeline of CAT12 should be now less subject to changes. I had difficulties in the past to deal with all different data (e.g. quantitative maps) and many updates affected the preprocessing. Hopefully, this will be more stable now and thanks for your patience.
Best,
Christian
