speedy_subset

speedy_subset(df, roi_sids)

Speedy intersects is meant to subset large (long) STAREDataFrame to a subset that intersects the roi.

This method works particularly well if

1. the df has significantly more SIDs than the roi_sids

2. The SIDs of the df are at higher level than the roi_sids

Parameters

df: starepandas.STAREDataFrame

the dataframe that is to be subset

roi_sids: array-like

a set of SIDs describing the roi to whch the df is to be subset
