I figured out how to do the sequential temporospatial PCA (thanks!). Now, I want to export the factor scores (in microvolts) from the temporospatial PCA to characterize each subject by one amplitude for every combination of condition, temporal factor, and spatial factor.

Looking through the tutorial, I see a couple options:

1. The factor score matrix is in the PCA tab of the Edit window, and I could export the factor scores. A couple problems here, though. Are the factor scores in microvolts? Also, there is no column for subject ID and condition, so I would have to guess which row corresponds to which subject and condition.

2. I could use the AutoPCA function to generate the voltage for every subject and condition for each of the temporal and spatial factors. This, however, appears to be the voltage accounted for at the peak time point and peak channel for a given temporospatial factor, and not a representation of the entire factor structure (all of the time points and channels) for that temporospatial factor.

Is it possible to export the factor scores from a temporospatial PCA that are represented in microvolts and represent the entire factor structure for a given temporospatial factor (not just the peak time point and peak channel)?

I really love the toolkit, and thanks so much for your help through the learning process. I really hope to use it as my go-to tool for data reduction.
