Cell Ranger multi supports a number of library types from the same experiment, including Gene Expression, CRISPR, VDJ-T, VDJ-B, Antigen Capture (BEAM), and Antibody Capture (Cell Surface Protein Capture).
In order to organize output metrics resulting from multiple libraries and multiple samples, the metrics_summary.csv file has one metric per row and the following columns:
| Column Name | Description | 
|---|---|
| Category | Categorized the metric based whether it applies to only cell-associated barcodes ( Cells) or to the whole library (Library). This distinction corresponds to whether a metric is found in the "Library" or "Cell" view of thecellranger multiweb summary. | 
| Library Type | Either Gene Expression,VDJ T,VDJ B,Antigen Capture,Antibody Capture, orCRISPR. | 
| Grouped By | Describes the categories that a metric may describe/group by. Example categories are Physical library ID,Fastq ID. | 
| Group Name | The name of the Grouped Bycategory. Example:GEX_1(a physical library ID),Seq_GEX_1(a fastq ID),GRCh38(a genome name), etc. | 
| Metric Name | The name of the metric. | 
| Metric Value | The value of the metric. |
