Hi, sorry for more questions, but i have a few. When running the first step of the lme implemented tools, doing the command *mris_preproc* --qdec-long qdec.table.dat --target study_average --hemi lh --meas thickness --out lh.thickness.mgh (assembles your thickness data into a single lh.thickness.mgh file), am I correct that this just needs to be a "normal" cross-sectional qdec table that free surfer subsequently makes into long format by --qdec-long option? so the lnogitudinal qdec table is only used in the two stage modell? This too just uses the cross-sectionally derived scans? Im confused where the .long runs become used?

thank you and kind wishes

Hi,

I would like to make my freesurfer longitudinal qdec table for the to use in the lme matlab tools. However, does the fsid need to refer to the longitidunally derived subject; eg XXX.long, or the cross-sectionally derived subject, eg XXX. Im not sure based on the specification online. Kind Regards

Anna
