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
