Hi Lucy, 

I'm not an expert but I've been using this software for a few months now. I believe the jackknife sensitivity analysis has to be completed manually (i.e. repeating the analysis leaving one study out each time) with the new SDM-PSI version you're using, as there is no inbuilt function for this as there was for the previous AES-SDM. If I remember correctly, there are other forum posts here discussing this, where the developers provide more in-depth responses/refer to literature where you can read more about conducting jackknife sensitivity analyses manually. 

Can I ask why you chose the sig threshold of p .025? I've been struggling with what stat threshold to use for my analysis, and so I'm curious to hear reasonings for particular threshold choices, e.g. why did you opt for the uncorrected over the tfce corrected? 

Best, 
Molly
