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
