Hi Arash,

PALM cannot be used for a meta-analysis. However, it can used for a mega-analysis.

The way as the exchangeability blocks and variance groups would be organised depends on the design and assumptions, which would also affect the use of permutations or sign-flippings. You may need to give more details, or consult the documentation.

All the best,

Anderson

Dear FSL Experts,

Although it may seem obvious, I was wondering if PALM could be used for meta-analysis with the following exchangeability blocks (e.g. for two datasets: 1 [1.5 Tesla dataset] and 2 [3 Tesla dataset] )?
