External Email - Use Caution Dear FS experts,
I have run the longitudinal pipeline on a dataset with three timepoints. I am particularly interested in the longitudinal hippocampal and amygdala data and want to run LME on these. I've made the qdec table with the id age, sex and time between scans etc. and have exported all the hippocamapal and amygdala volumes to csv files to merge with demographic data. Should I smooth the hippocampal and amygdala measures before running the LME? Do I run Qcache and if so do I use recon-all -long SubID_tp1 subIDbase -qcache In the LME wiki instructions it gives an example for the mass-univariate approach on thickness. Is the study_average referring to the fsaverage ? Should I be using the ICV from the cross-sectional runs or the ICV measures in the "long" folders which refer? Thanks and any help is very much appreciated. Erik
