Mass spectrometry terms
ESI: Electrospray ionization
MALDI: matrix-assisted laser desorption/ionization
TOF: time-of-flight
1DE/2DE: one- or two-dimensional gel electrophresis
CID: collision-induced spectra
Phylogenetic algorithm selection
See http://pga.lbl.gov/Workshop/April2002/lectures/Olken.pdf for details, in brief:
• Continuous characters, lots of data, few computing resources ==> Neighbor joining
• Discrete characters, few mutations / homoplasy ==> Maximum Parsimony
• Discrete characters, limited sequence lengths, some homoplasy ==> Maximum Likelihood Estimation
• Discrete characters, many taxa ==> Supertree
• Complete genomes ==> Whole genome phylogeny
Statistics R command
. Read a file
height <- read.table("H:/public folder/hzhang/R/height.txt",header=T)
. Print summary
summary(height)
. Set the factor level
height$Treatment <- relevel(height$Treatment, ref="kitaake")
. Variance analysis
summary(lm((height$Height~height$Treatment)))
