Dear export,
      good afternoon!
i have some problems on conn.
1. During the part of  second-level results , there is a blank called Between-subjects contrast , on the menu there is only example of two groups comparison , now i have 3 groups or even more than 3, which numbers i should type inside the blanks? i want to compare each two of them .especially inside patients groups.
2.On the left side of the window ,there are 3 kinds of analyses types. yesterday i tried seed-to-voxel but can not run ROI-to ROI the same time after i did run that.And when clicked voxel-to-voxel button , there is an error window appeared saying:"Data not prepared for results.Pree "done"in the analyses window". i did as it said.but no difference.so , are these 3 analysing types can not be used at the same time?
3.About the analysis results.
  The images on the right side of the window, i can not understand clearly. i got one black circle , one white circle with small red point inside,and  another 2 red points together.i do not know which is patient's and which is healthy group's.Can you give me some suggestions to understand the results?
Thank you very much .
Best wishes and waiting for your reply .
