Hello!
I would like to know which contrast is more correct if I have a healthy control group and 3 subgroups of patients using randomise, Glm and its outputs:
1) Analyze the healthy control group contrasting to each depressive group separately (i.e. analize 3 Glm), or
2) Analiyze all groups together in Glm (with their correct contrast)
I have done both analysis and there are different outputs in fslview and in cluster command, which is the most recommended test?
Thank you,
Pat.
