Question about unexpected error with baseline corrected EFA

[Feng Yu]

Hi Jesse,

I am trying to do a baseline subtracted EFA analysis and following error come out. Could you help me with this issue?

Thank you.

Hi Feng Yu,

Before getting to the error, I don't recommend using EFA with a baseline subtracted dataset, that causes all kinds of difficulties. If you need to do deconvolution and correct for a changing baseline you should use REGALS on the subtracted (but not baseline corrected) data and include one or more components in the REGALS deconvolution for the baseline.

I was able to confirm that the error you reported occurs with a baseline corrected dataset that I have (which I don't typically test for EFA or REGALS). I appreciate the bug report and will make a fix available in the next version of RAW. For the moment, please only do EFA on subtracted datasets, which is the recommended approach.

All the best.

- Jesse
