Class NMRiFile Description
7.5.1
Introduction
Every data file suitable for use in the NMR data processing packages from New Methods Research,
Inc.1 (e.g. NMR1 and NMR2) has a standard internal format. Class NMRiFile was constructed in
order that users of GAMMA are able to efficiently manipulate such files.
7.5.2
NMRiFile Structure
The internal design of Class NMRiFile is quite simple. It contains the quantities defined in the following table.

Most manipulations within NMRiFile are performed with the C++ class File. The other quantities
are defined mostly for convenience and/or because they are constants for all NMRi files.
1. NMR1 and NMR2 are a products of New Methods Research, Inc., 7 East Genesee Street, Syracuse, NY,
13210. Phone: (315) 424-0329, FAX: (315) 424-0356.GAMMA was tested on Sun systems running the Sunviews operating system. NMR1 release 3.8 and NMR2 release 3.5 were the manuals referred to during the
programming.
