Question about the random seed used in SDM-PSI permutation test

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
