Projects

Borrelia genome evolution (Led by Saymon)

1. Goal 1. Estimate time of cross-Atlantic dispersal using core-genome sequences
2. Goal 2. Investigate codon biases with respect to levels of gene expression. Data file:
   File:B31-cp26.txt

Identification of host species from ticks (Led by Lily [after first-level])

1. Goal 1. Protocol optimization for PCR amplification of host DNA from ticks
2. Goal 2. Protocol development: library construction for MiSeq
3. Goal 3. Development of bioinformatics protocols and sequence database

Pseudomonas Genome-wide Association Studies (GWAS) (Led by Mai & Yinheng, in collaboration with Dr Xavier of MSKCC)

1. Goal 1. Association of genes/SNPs with biofilm formation and c-di-GMP levels: Manuscript preparation
2. Goal 2. Association of genome diversity with metabolic diversity

Machine learning approaches to evolution (Led by Oliver & Brian)

1. Goal 1. Implement Hopfield network for optimization of protein structure
2. Goal 2. Neural-net models of OspC. Structural alignment (S2 from Baum et al 2013):

1. Goal 3. K-mer-based pipeline for genome classification

Notes & Scripts

• (Weigang) A sample R script to parse Table S2 from Baum et al 2013, sera-antigen reactivity measurements

# preliminaries: save as TSV; substitute "\r" if necessary; 
# substitute "N/A" to "NA"; remove extra columns

x <- read.table("table-s2.txt4", sep="\t", header=T)
View(x)
colnames(x)
which(x[,8]=="A")
