Struct ExpressionMatrix 

pub struct ExpressionMatrix {
    pub genes: Vec<String>,
    pub samples: Vec<String>,
    pub values: RecordBatch,
}

Expression matrix with genes as rows and samples as columns

The values field is an Arrow RecordBatch where:

• Each row represents a gene
• Each column represents a sample’s expression values for all genes
• Column names are GSM accession IDs
• Values are Float64 (null for missing data)

Fields

genes: Vec<String>

Gene symbols (rows), ordered to match RecordBatch rows

samples: Vec<String>

Sample GSM accession IDs (columns), ordered to match RecordBatch columns

values: RecordBatch

Arrow RecordBatch with gene expression values

Schema: one Float64 column per sample, column name = GSM accession

Implementations

impl ExpressionMatrix

pub fn get(&self, gene: &str, sample: &str) -> Option<f64>

Get expression value for a specific gene and sample

Returns None if the gene or sample is not found, or if the value is null.

Trait Implementations

impl Clone for ExpressionMatrix

fn clone(&self) -> ExpressionMatrix

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExpressionMatrix

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
