Hi Joshua,
There’s actually a recently-discovered bug in pipeline-config parsing that is reverting any changes to seed_based_correlation_analysis to the default (which includes run: Off), so to answer your questions:
What are the expected outputs of dual regression preprocessing?
Files with desc-DualReg in the name ending with _correlations and _statmap
Am I misunderstanding something?
Nope, just hitting a bug! It will be fixed in the shortly forthcoming C-PAC v1.8.5.
If you can’t wait a few weeks for the fix and are comfortable using a less-than-fully-tested development image, docker://ghcr.io/fcp-indi/c-pac:fix_minimal-schema includes the proposed fix for this bug.
I’ll post back here when 1.8.5 is released with the fix included.
