importorigin(x)

Arguments

x

a character string of the name of the text file in csv format exported from Origin7 ITC data sheet

Value

A list with each column in the input file as one component. Elements in each component are converted to the numeric type. NAs are generated if non-numerical values are present. NAs at the end of each component are deleted. These components are in the list if imported from Origin7: DH,INJV,Xt,Mt,XMt,NDH,B

DH

heat exchange in mcals for each injection

INJV

injection volume in ul for each injection

Xt

ligand concentration in the ITC cell before each injection

Mt

protein concentration in the ITC cell before each injection

XMt

the molar ratio of ligand to protein in the ITC cell after each injection

NDH

heat exchange in cal/mole for each injection

B
