RBMRB (version 2.1.7)

chemical_shift_hist: Plots chemical shift distribution

Description

Plots the histogram (or) density of chemical shift distribution of a given atom from amino acid (or) nucleic acid from BMRB database. Optionally particular atom can be specified in the parameter

Usage

chemical_shift_hist(res = "*", atm = "*", type = "count", bw = 0.1, cutoff = 8)

Arguments

res

residue name in NMR-STAR atom nomenclature ; Example: ALA,GLY ; default '*' (includes everything)

atm

atom name in NMR-STAR nomenclautre ; Example :CA,HB2 default '*' (includes all atoms)

type

count ; other than count will assume density plot

bw

binwith for histogram; default value 0.1ppm

cutoff

values not with in the cutoff time standard deviation from both sides ofthe mean will be excluded from the plot;default value 8

Value

R plot object

Examples

# NOT RUN {
#plt<-chemical_shift_hist('ALA')
#plots the histogram of all atoms of ALA
#plt<-chemical_shift_hist("*","CB*")
#plots  CB chemical shift distribution of standard amino acids
#plt<-chemical_shift_hist('GLY',type='density')
#plots the density plot
# }
