After FWE,no distinct difference.
i conduct VBM-meta analysisi using the SDM and have finished preprocess,mean,threshold p=0.005.But when i fulfilled the FWE through 3 days,the corrected(tfce) brain atrophy areas and the uncorrected is no distinct difference,still a large piece. Each of articles sdm_table t values were set to the minimum t value of each article.

RE: After FWE,no distinct difference.
Dear Rick, 

If you set an uncorrected threshold of 0.005, it can be possible that the cluster are similar to a FWE corrected threshold of 0.05, or did you also used a FWE < 0.005??

Best, 
Lydia
