I've got a very basic question related to group analysis. If I want run a correlation of voxels in the cortex with a variable controlling for another continous variable, how do I do this. I know how to run them both in a GLM simultaneously by coding the matrix 0 1 1, however, how do I look at the first variable after controlling for the other? Here is an example of my current fsgd input (I want to control for income):
GroupDescriptorFile 1
Title MyTitle
Class Class1 plus blue
CLASS Class2 circle green
SomeTag
Variables impulsivity income
Input subjid1 Main 10 100
Input subjid2 Main 20 200
etc.
