Hello,

I recently completed the preprocessing and denoising steps for my pediatric dataset and noticed that some subjects have very low degrees of freedom after denoising. The original degrees of freedom were 163, but for some subjects they drop to fewer than 10.

My understanding is that this reflects a limited amount of usable data. I am therefore considering excluding subjects with very low degrees of freedom. But I was wondering whether there is a recommended cutoff for degrees of freedom when excluding subjects, or whether exclusion should instead be based on a different metric.

Thank you!
