Hello Ludavica,
Thank you so much for your help! I did have the T1 weighted images so I put them as main structural image in the registration tab in Melodic.
However, I have another question that I was meaning to ask regarding FIX. At first, I assumed that FIX would perform Melodic ICA itself and then it would classify the components from the files that I gave them. It would do that automatically thanks to my Training data (which I obtained from manually classifying the components from 10 subjects).
However, according to the FIX UserGuide (http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FIX/UserGuide), I need to apply FIX to an .ica folder like so:
/usr/local/fix/fix -c <Melodic-output.ica> <Training.RData> <thresh>
I just wanted to ask if this is the case and therefore I would need to apply Melodic ICA to all my subjects right? Maybe it is my computer but obtaining the output for Melodic is very time consuming and I have over 100 patients. So I just wanted to ask if this is what I need to do: run Melodic for all of the subjects, select 10 and manually classify their components, then create the training data, apply it to the rest of the patients that have Melodic ICa folders. Is this correct?
Finally, I believe that I could run multiple subjects at the same time on FIX right? I don't want to get confused with multiple-level analysis... If I select different files as inputs for 4D data and one output folder, it still would do single subject analysis for each and every one of my input files and create an ICA folder separately within my output folder selected?
Thank you very much,
Laura
