Hi, 

I am using SDM-PSI for a voxel-based morphometry meta-analysis and have a question regarding the permutation test.

Does anyone know what type of random seed is used in the permutation procedure? Specifically, does SDM-PSI use a fixed random seed (ensuring identical corrected results across repeated runs) or a randomly generated seed (which would produce slightly different corrected results each time)?

Thank you very much for your time.

Best wishes,
Kaiyu
