Hello SPM experts,
I am working on a longitudinal VBM analysis with 3 time points in a pediatric cohort. This study has an unbalanced design with about 120 scans collected at all 3 time points, 40 scans with 2 time points, and 40 scans collected at 3rd time point only.
I would like to use CAT12 to process the data for VBM analysis. The segment longitudinal data pipeline would be optimal for our longitudinal data, but we would like to additionally include those scans only collected at time point 3. my question is: can we combine pipelines of the 'segment longitudinal data' and the 'segment data' to separately process both longitudinal data and cross-sectional data? Then, will the file formats be compatible to combine for statistics?
Furthermore, is it appropriate to take an average age to use one tissue probability map for this cohort scanned between the ages of 4-14?
Thanks,
Stefani
