Optimization by GA

  • Identified a sequence with d<=43 to all 16 alleles (using DEAP)
  • next, write a fitness function to minimize the maximum distance to any of the 16 alleles; run ~10 times
  • output in FASTA file and do a tree
Edgar, Lia Brian
OspC antigenecity model Develop model with mice data by Invanova et al Nevila, Brian Brian
OspC per-site model Quantify per-site importance with likelihood, i.e., Prob{fit->0, given that CW50, site=i}
  1. For allele A, file has been generated at CW50=50
  2. Radhika has turned strings into {0,1}
  3. To do: plot fitness ~ pos
  4. CW50 values: given by Mohammad, estimated by using CW50=-(intercept/slope)
  5. Estimate importance using GA: fit = sum(1-p[i]), with the fitness/error function: error = |fit[obs] - fit[simulated]|; using GA to minimize the error; output p[i] as results (importance)
