Hello FSLers
I am pretty new to FSLs ICA
i have a question regarding selection of components:
I ran melodic with the default 30 components output and the melodic file has 30 volumes referred to as components (0-29), and then flirted it to hte patient's T1
i have two questions:
1. if a subject has a single volume that includes all the relevant brain areas we are interested in, should we consider just this volume. If yes, what about other volumes that have parts of the areas we are interested in
2. on the other hand, what ff we have a patient that has all relevant areas in one volume and another patient that has a number of volumes that have parts of the areas we are interested in
3. Is there any weighting with respect to the number of components selected per individual?
Your response is highly appreciated
Thanks & Regards
