I have a map of t-statistics that I created outside the regular workflow (a searchlight similarity analysis). I’d now like to threshold it, but I’m not sure how that can be done. I can of course threshold at a specific t-value, but I’d like to run correction for multiple comparisons and set a specific p-value.
I thought to use the SPM Threshold function, but that requires an SPM.mat file. I checked the option of tweaking the code to input the relevant parameters from the SPM.mat file myself, but I’m not sure how to calculate some of them (particularly SPM.xX.erdf).
Does anyone happen to have helpful pointers?
