FMRIprep multi-echo


Hi All,

I am using fMRIprep version 1.5.0rc1 to preprocess some multi-echo data and I noticed that fMRIprep automatically combines the echos. Is there a way to run the preprocessing steps without combining the echos?
Or should I use one of the earlier versions instead?

Thanks so much!



Hi @jngx47f,

If you’d like to process the echos individually, check out the --echo-idx flag !

That being said, if you’re using the individual echos to submit to e.g. tedana you might want to check out Combining fmriprep with ME-ICA from tedana

Hope that helps !



I will try that. Thank you so much!

I want to keep the echos separate to calculate realised volatility. I have a feeling I’m dealing with some particularly rough data.
