Hello,
I have a question regarding correlation (linear regression) in FSL. My understanding is that it can be done in FSL.
I have 268 subjects and I would like to run a linear regression (correlation) between gray matter images and a continuous variable. I have the gray matter images (registered) as a 4D image. I tried to use the Glm_gui to define the design and contrast. I selected higher-level/nontimeseries design, then changed the number of inputs to 268 and number of main EVs to 1. I clicked on paste to see if I was able to paste the continuous variable for each corresponding image. However, it is not possible. How can I define the continuous variable?
Also, would it be possible to have feedback on the command that I need to run (using randomise)?
I appreciate the help.
Thank you,
Bedda
