AROMA #325

Open shanaahall opened 4 years ago

shanaahall commented 4 years ago

Hello,

I apologize if there is documentation on this. I could not find it but I very well may have missed it. On the xcp readthedocs site, it says that the aroma streams do not strictly follow the original implementation of aroma from the Pruim paper. From what I can tell, this is because the components are derived from smoothed data but they are removed from the unsmoothed data. Is that correct and if so, is that the only difference between the xcp implementation and the original implementation? Also, would you mind sharing how you decided to implement aroma in this way? Just asking out of curiosity.

Thanks!

Hi @shanaahall , xcp doesn't run aroma. What xcp does is only regression of selected regressors from fmriprep regressors. The fmriprep aroma is simply base on fsl-melodic as implemented in python : https://github.com/maartenmennes/ICA-AROMA
