Dear all, I just read the article 'Bayesian model selection for group studies' http://www.ncbi.nlm.nih.gov/pubmed/19306932?ordinalpos=1&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_DefaultReportPanel.Pubmed_RVDocSum and I wanted to ask how can I compute the exceedance probability in ERP data. Is there already a script implemented in the SPM8b? I have already compared 2 models and I have the conditional model probability. I looked up the SPM_BMS, but I do not know how to run it for my EEG data. Or is there another solution? Thanks for any help Best, Danai Dima
