Inputting SANGER File (Excel, TSV, CSV)

A Cube that takes in processed FASTQ or FASTA and condenses by user-defined region of interest (ROI). The default ROI is the full-length sequence including CDRs. If sequences share the same ROI, only the most abundant full-length sequence is retained

Calculation Parameters

  • Full/Partial alignment to annotate CDRs (cdr_method) type: string: Align query sequence to the entire germline or to partial regions to annotate. IMPORTANT POINT 1: Full should be used for amino acid inputs. IMPORTANT POINT 2: For DNA inputs, ‘full’ works better for natural repertoires (e.g., when NOT using custom annotation file) and ‘partial’ works better with DNA for synthetic/degenerate antibodies (e.g., when uploading a custom annotation file).
    Default: full
    Choices: partial, full
  • CPUs (cpu_count) type: integer: The number of CPUs to run this cube with
    Default: 1 , Min: 1, Max: 128
  • Cube Metrics (cube_metrics) type: string: Set of metrics to be collected

    Choices: cpu, disk, memory, network
  • Provide a Customized Amino Acid Annotation File with Alignment Scheme of Interest (for Sanger) (custom_annotation_aa) type: file_in: ONLY REQUIRED for custom scaffolds like the Specifica Gen3 Library: OPTIONAL for natural antibodies. If provided, will override annotation and species/database selection settings.
  • Provide a Customized DNA Annotation File with Alignment Scheme of Interest (for Sanger). (custom_annotation_dna) type: file_in: ONLY REQUIRED for custom scaffolds like the Specifica Gen3 Library or codon optimized sequences: OPTIONAL for natural antibodies. If provided, will override annotation and species/database selection settings.
  • Temporary Disk Space (MiB) (disk_space) type: decimal: The minimum amount of disk space in MiB (1048576 B) this cube requires. Due to overhead, request a couple hundred MiB more than required.
    Default: 5120.0 , Min: 128.0, Max: 8589934592
  • Keep Only Functional Sequences, Sanger (filter_functional) type: boolean: Eliminates non-functional sequences, truncations, stop-codons, frame-shifts.
    Default: False
  • GPUs (gpu_count) type: integer: The number of GPUs to run this cube with
    Default: 0 , Max: 16
  • Heavy Chain CDR1 Annotation Scheme (heavy_cdr1) type: string: Indicate the annotation scheme for Heavy CDR1

  • Input FASTQ/A, CSV, TSV, or XLS for Sanger (or Low-Throughput Data) (input_fastq) type: file_in: Input FASTQ/A in standard format or CSV, TSV or Excel in format id,sequence. ENSURE THE SUPPLIED FILE DOES NOT HAVE A HEADER COLUMN, which may lead to aberrant behavior.
  • Instance Tags (instance_tags) type: string: Only run on machines with matching tags (comma separated)
    Default: “”
  • Instance Type (instance_type) type: string: The type of instance that this cube needs to be run on
  • Is the Input SANGER a Single Domain or Chain (is_single_dom) type: boolean: Turn ON if sequence covers only a single chain/domain (e.g. VH or VL). This will automatically adjust the acceptable minimum read length and annotation query length. If this is turned ON, both chain_1 and chain_2 columns are provided in the output file but they will be identical. IMPORTANT: has no effect on amino acid inputs, only on DNA inputs.
    Default: False
  • Length of K-mers for germline identification (k) type: integer: Length of K-mers for germline identification (default 9 for DNA). If sequences differ signifacntly from the germline, smaller (5-7) may help finding the correct result.
    Default: 9 , Min: 5, Max: 12
  • Length of query chain (len_chain_query) type: integer: How many bases or amino acids in each end of the read to use to query for a antibody chain

    Default: 650
  • Minimum votes for germline assignment (min_votes) type: integer: Minimum number of matching K-mers for germline assignment. Higher numbers make the algorithm more stringent at the expense of not annotating some sequences.

    Default: False
  • Region of Interest (ROI) For Condensing Sequences (roi) type: string: This will condense the Sanger sequences based on the ROI based rank ordered on abundance.
