Read10x: Read AIRR/10x report files

Description

Read10x reads AIRR file and/or contig/consensus/clonotype file generated by 10x cellranger (> 6.0). Generally AIRR file: airr_rearrangement.tsv (from cellranger); contig files: all_contig_annotations.csv, filtered_contig_annotations.csv; consensus file: consensus_annotations.csv; clonotype file: clonotypes.csv. (.gz supported)

1. AIRR + filtered_contig: Read10x will read AIRR and add it 'fwr.., cdr.. and full_length' column based on filtered_contig file.

2. only one file: Read10x will return a data.frame for this file.

3. AIRR/contig + consensus/clonotype: Read10x will ignore consensus/clonotype file when either AIRR or contig file is given. Note that when AIRR + all_contig, only contigs in AIRR will be return.

4. consensus + clonotype (no AIRR nor contig): Read10x will ignore clonotype file when consensus file is given. (Don't worry about the information of inkt/mait_evidence in clonotype, these can be reproduced in downstream analysis.)

Usage

  consensus_file = NULL,
  clonotype_file = NULL,
  verbose = TRUE
