Hi ISAS experts,


I am just starting to use your tool. Thanks for the excellent tutorial/instructions you have set up in the website.

My aim is to run a group analysis with six pairs of inter/intra-ictal SPECTS. With the instructions in the website, I easily performed the individual analysis (for each patient), but now I want to proceed to a second-level analysis to identify and mark hyper and hypoperfusion areas for the whole group of patients.

I suppose I should start in the multiple image calculations option on the Data Tree Manager menu, but I am struggling to find instructions on how to do it in you website.

Could someone please point me towards the proper steps in the analysis of the group of images?
