NGS Key Selection Parameters

Maximum Number of Full-Length Sequences (number_of_seqs_ngs_picking): Indicate the maximum number of full-length, non-redundant sequences. This value depends on the total number of non-redundant sequences, maximum # of clusters and the maximum # of sequences per cluster. If the total number is below desired, try adjusting max # of clusters or max number of sequences per cluster. Alternatively, if you want to fill quota with additional sequences per cluster turn on the ‘Attempt to Fulfill the Desired Number of Sequences Quota’ parameter

  • Required

  • Type: integer

  • Default: 100

Maximum Number Sequences Per Cluster (max_seq_per_cluster): Indicate the maximum number of unique full-length sequences per given cluster. This value may be exceeded if the ‘Write the Automated Top Clones Output to CSV File’ is turned ON

  • Required

  • Type: integer

  • Default: 10

Maximum Number of Clusters Preferred? (number_of_clusters_to_select_from): Indicate the maximum number of clusters that you want to choose from. This value may be exceeded if the ‘Write the Automated Top Clones Output to CSV File’ is turned ON

  • Type: integer

  • Default: 40

Metrics for Ranking (picking_choices): Place metrics in order of ranking (if nothing, ranks by full-length count)

Attempt to Fill the Desired Number of Full-Length Sequences Quota (quota_attempt): This will attempt to fulfill the total number of sequences quota if goal of desired number of full-length sequences is not reached by 1) selecting additional clones across lower in rank aross designated clusters followed by 2) selecting the remaining top ranked clones from different clusters by prioritizing top clones. NOTE: if turned on, this is likely to result in a greater number of sequences per cluster and if quota still not met, more clusters then designated in total to reach the desired number of full-length sequences goal

  • Choices: [True, False]
