External Email - Use Caution
Hello,
I am doing a longitudinal analysis for which I have already qcached my data using the long_mris_slopes command.
I am having issues figuring out how to run the mri_glmfit command for my longitudinal two stage model. I'm interested in comparing the spc over time between two groups after controlling for age and gender. The tutorial on the longitudinal two stage model however only shows how to do it for one sample.
Am I still expected to use contrasts and make glm directories like the cross-sectional group analysis tutorial suggests? I was just confused because the code is different. I have a longitudinal table so I assumed that would be enough, but do I still need to make a FSGD file that is basically the same as the longitudinal file?
Thank you for your help,
Arsenije
