Dear experts,

I use censoring or scrubbing of volumes as a preprocessing step in my resting-state data. This leads to errts files which have certain volumes as all 0s.

My question is, when I am going to perform functional connectivity analysis with these censored datasets, how do I deal with the 0 values in the time series? Should I change my code such that only non-zero values are correlated between seed and target time series? or is there a more straightforward way of dealing with 0s in the data time series?

Thanks in advance for your help.
