Category Paths

Follow one of these paths in the Orion user interface, to find the floe.

Description

This will process single file in either FASTA, FASTQ, TSV, CSV, or EXCEL format. Each sequence ID typically represents unique well ID. If using TSV, CSV or EXCEL files as input, should format each row as follows:

  1. column A = id

  2. column B = sequence (dna or amino acid), WITHOUT header.

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).
