Cell Ranger4.0, printed on 11/05/2024
cellranger vdj pipeline produces V(D)J annotations on the assembled contigs and on the clonotype consensus sequences in multiple formats.
File type | Description
|-
CSV | High-level annotations with one contig, consensus, or clonotype per row. JSON | Detailed annotations, including alignment coordinates and amino acid translations. BED | Germline V(D)J segments as features, for use with a tool like IGV. TSV | Used for the AIRR rearrangement format of VDJ contigs and consensus sequences.
File | Description
|-
clonotypes.csv | High-level descriptions of each clonotype.
consensus_annotations.{csv,json} | High-level and detailed annotations of each clonotype consensus sequence.
filtered_contig_annotations.csv | High-level annotations of each high-confidence, cellular contig. This is a subset of all_contig_annotations.csv.
all_contig_annotations.{csv,bed,json} | High-level and detailed annotations of each contig.
airr_rearrangement.tsv | Annotated contigs and consensus sequences of VDJ rearrangements in the AIRR format.

| length | The contig sequence length in nucleotides. |
| chain | The chain associated with this contig; for example, TRA, TRB, IGK, IGL, or IGH. A value of "Multi" indicates that segments from multiple chains were present. |

| cdr3_nt | The predicted CDR3 nucleotide sequence. |
| reads | The number of reads aligned to this contig. |
| umis | The number of distinct UMIs aligned to this contig. |
| raw_clonotype_id | The ID of the clonotype to which this cell barcode was assigned. |
| raw_consensus_id | The ID of the consensus sequence to which this contig was assigned. |
| Column | Description |
|---|---|
| clonotype_id | The ID of the clonotype to which this consensus sequence was assigned. |
| consensus_id | The ID of this consensus sequence. |
The remaining columns are shared with those under the Contig Annotation CSV Files section.
