NIAID Large Internal Delete (LID) HIV Genomes

- GOAL: PacBio sequence HIV genome mixtures that have been isolated by SGA that have shorter lengths due to large internal deletions (LIDs) and compare results to MiSeq results so that algorithms can be perfected. We look forward to seeing the unblinded MiSeq estimates for the runs we present here. - Here is the sample list of the shorter genomes sent to PacBio:
Name Samples AvgEstimatedSize ---- ------- ---------------- Pt3-95-3mix-A-short 1995: s2, s19, s20, 2200 Pt3-95-5mix-B-short 1995: s1, s3, s8, s10, s11 3300 Pt3-95-6mix-C-short 1995: s4,s12,s13,s14,s16,s18 3400 Pt3-95-6mix-D-short 1995: s5, s6, s7, s9, s15, s17 4700 Pt3-01-3mix-E-short 2001: s29, s30, s31 2400 Pt3-01-4mix-F-short 2001: s21, s23, s27, s32 3300 Pt3-01-5mix-G-short 2001: s22, s24, s25, s26, s28 3400
- For this set of results, we give consensus genonomes for the Pt3-95-3mix-A-short (3 expected genomes) and Pt3-95-3mix-D-short (6 expected genomes) runs. Below we give 4 download links applying two algorithms to these two runs. - By comparing the results against the unblinded MiSeq estimates, we will be able to iterate the algorithms to get them perfect. We will start with two runs and then be able to use the other runs as new "test sets" to make sure our algorithms don't overfit. After getting everything perfect, the goal is to apply the final algorithms to the 20-mix of full length HIV genomes as the final validation test set. ================================

Consensus Methods

- We try two classes of algorithms for these results: Long Amplicon Analysis (LAA) and ClusteringConsensus (CluCon). -- Long Amplicon Analysis (LAA) is a de-novo method that works to cluster out more widely divergent genes and then finds smaller scale differences like SNPs within the genes. It was originally developed for multi-gene HLA sequencing. - LAA was run using the standard analysis protocol in SMRTportal. -- ClusteringConsensus (CluCon) is a reference based approach that clusters out different genomes and then mitigates noise using consensus within each clustering in a recursive fashion. - CluCon was run using a development version of the code available at https://github.com/mpsbpbi/clusteringConsensus - The development version works to handle PacBio error modes to achieve better performance. - An HIV HXB2 reference was used with the middle deleted. This was necessary because the deletions were so large, the alignment was broken into two separate parts. ================================
