importorigin: Import data from Origin7 ITC data sheet

In Ritc: Isothermal Titration Calorimetry (ITC) Data Analysis

Description

The importorigin function imports integreted ITC data from csv files. The source csv files can be generated, for example, by exportation from spreadsheets generated after integration in Origin7 ITC module.

Usage

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	heat exchange in cal/mole for each injection, fitting results from Origin7

Note

Origin7 with ITC module is software from Microcal Inc.
