Statistic analysis with eLORETA files

Hi everyone,
Given that the loreta statistics program only has several simple design options, I wonder if there is a way to conduct more sophisticated statistics on .slor files. For example, two or three-way repeated-measures ANOVAs.

For now, I have .slor files from the utilities LORETA-KEY program, with 3 within-subject factors. Any recommendations for data analysis?

Thank you so much for reading my question and please ask any follow up questions if this is not too clear.

Brainstorm cannot read LORETA-KEY files, unfortunately I don't think we can be of any help here.

Thank you Francois for the info!
