Struct DenseRunVariable 

pub struct DenseRunVariable {
    pub name: String,
    pub source: String,
    pub values: Vec<f64>,
    pub sampling_rate: f64,
    pub run_info: Vec<RunInfo>,
    pub entities: StringEntities,
}

A dense run variable with uniformly-sampled time series data.

Represents continuous signals such as physiological recordings (_physio.tsv.gz), stimulus waveforms (_stim.tsv.gz), or confound regressors (_regressors.tsv). Data is stored as a vector of f64 values at a fixed sampling rate.

Supports resampling to different rates via resample() and TR-based downsampling via resample_to_tr().

Corresponds to PyBIDS’ DenseRunVariable class.
