old fashioned projector lists in my yaml file returned ...

Update: YAML linted. Still having issues passing legacy proj_nums

[larsoner]

It's closed now, I assume it's working now? I would have thought something like this would have worked:

proj_nums: [[1, 1, 0], [0, 0, 0], [1, 1, 0]]

As Eric implies, the problem in the original post is the curly brackets, they shouldn't be there.

[ktavabi]

Tried both. Different trace back without curlies.

weird. I just ran yesterday with something like this in the YAML:

preprocessing:
    ssp:
        proj_nums: [[1, 1, 0],  # ECG: grad/meg/eeg
                    [0, 0, 0],  # EOG  (combined saccade and blink events)
                    [0, 0, 0],  # Continuous (from ERM)
                    [0, 0, 0],  # HEOG (focus on saccades)
                    [0, 0, 0]]  # VEOG  (focus on blinks)

I'll try again after Eric merges code bases.
