Description
This will process paired or unpaired ab1 files. Each sequence ID typically represents unique well ID. This will condense AA sequences based on user-defined option (Default = Full-Length, Framework included). Redundant sequences will be condensed and the ‘id’ field will contain a ‘:’ separated list of IDs (typically Well ID). This FLOE will calculate liabilities and biophysical properties by CDR (length, net charge, Parker hydropathy).

Trace Assembly and Contig Trimming Parameters
Read trimming stringency (trim_stringency): Stringency of read trimming prior to assembly. If value is 0, floe ignores this parameter and trims by length (see ASSEMBLE TRACES Cube hidden parameters to set lengths).To enable this parameter, choose an integer between 1-9. 1 is the most stringent and 9 is the least stringent. Incompletely trimmed reads may result in insertions in the assembled sequence but too much trimming may remove clone start and end sites.
Required
Type: integer
Default: 5
Name of forward primer (for_primer_name): Used to parse forward reads (read 1) from ab1 files by name. Primer should be the last part of the file name, e.g., Clone1-PrimerF.ab1. Click the + to add additional forward primer names. Recommended: include the delimiter (e.g., ‘-’) preceding the primer name to ensure it is removed from the clone ID in the output dataset.
Type: string
Default: []
Name of reverse primer (rev_primer_name): Used to parse reverse reads (read 2) from ab1 files by name. Primer should be the last part of the file name, e.g., Clone1-PrimerR.ab1.Click the + to add additional reverse primer names. Recommended: include the delimiter (e.g., ‘-’) preceding the primer name to ensure it is removed from the clone ID in the output dataset.
Type: string
Default: []
Trim # nucleotides from 3-prime end of read (trim_length_up): Trim # nucleotides from 3-prime end of assembled read to remove primer and/or extraneous sequence prior to annotation.
Type: integer
Default: 0
Trim nucleotides upstream of this sequence (trim_bases_up): Trim nucleotides upstream of this sequence to remove primer and/or extraneous sequence after assembly and prior to annotation. Identifies first instance of this sequence.
Type: string
Default:
Upstream sequence mismatches (mismatches_up): Number of substitutions to allow in upstream sequence match.
Type: integer
Default: 1
Trim # nucleotides from 5-prime end of read (trim_length_down): Trim # nucleotides from 5- end of assembled read to remove primer and/or extraneous sequence prior to annotation.
Type: integer
Default: 0
Trim nucleotides downstream of this sequence (trim_bases_down): Trim nucleotides downstream of this sequence to remove primer and/or extraneous sequence after assembly and prior to annotation. Identifies last instance of this sequence.
Type: string
Default:
Downstream sequence mismatches (mismatches_down): Number of substitutions to allow in downstream sequence match.
Type: integer
Default: 1
