What's your thinking for how best to apply RestingStateStats in the context of multi-run-fix? If we run RSS on individual runs, that won't really reflect the manner in which the multi-run data was cleaned.

The development version of RestingStateStats supports multi-run-fix. It produces a single output perconcatinated run.

Can you send me a copy? Not having the RSS equivalents per individual run is going to be unfortunate, but off the top of my head, I'm not sure if there is a meaningful way to apply the "variance partitioning" inherent to RSS to the individual runs in the context of multi-run FIX.

Well that is not hard, just compute the single run variances off of the multi-run cleanup stages. I'm less certain that it matters to not have single run variances though...

Not having them available for the individual runs is inevitably going to lead to "missing data" situations, given that individuals runs are a basic "unit" of data. e.g., If you wanted to use RSS to provide some QC measures for an analysis that is specific to a given task, that won't be possible.

Like I said one can compute single run versions if one saves out the intermediate timeseries. Which measures are you most worried about?

tSNR/CNR would be a natural one to want available per run. There may be others (haven't thought about it too deeply).

*Delete single run high-pass only files from multi-run fix and reapply multi-run fix
*Generate highpass volume timeseries if not already existing in ReApplyFixPipeline
