Dear SPM experts, Kevin
I encountered the same problem. It was proposed that the ReML does not
converge and that changing the option "Variance" to "equal" would solve this
problem, but the same error persist even with "equal variances".
Further suggestions will be appreciated. I have only three pairs that I
tried to analyze.
Best regards
Juergen
