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.

if any advice 
thanks so much
Rick

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

Hello, does the FWE process take 3 days?
