What is a PROT file?

A PROT file is an atom list created and used by XEASY, a Nuclear Magnetic Resonance (NMR) spectrum analysis application. It is a plain text file that describes an atom's nuclear magnetic resonance. PROT files are meant to be opened and viewed in XEASY, using the Load atoms option.

More Information

Scientists and researchers can use XEASY to perform a 3D spectrum analysis of macromolecules, using NMR. One of the measurements XEASY records is a macromolecule's atom list. The atom list contains the name and frequencies of a macromolecule's resonances, and it is saved as a PROT file.

Each PROT file contains several rows of numerical and text values. Each row corresponds to an individual atom, and contains identifying information about that atom. In order, each atom's row includes:

  • The atom's unique ID number
  • The atom's mean chemical shift in part per million
  • The deviation of the atom's assigned peaks from the mean value
  • The atom's name
  • The atom's fragment number
  • The atom's reference lineshapes

To create an atom list in XEASY, scientists use the program's Write atoms (chem.shift) [wc] command. This produces a PROT file for the current macromolecule.

How to open a PROT file

You can open a PROT file in XEASY (Linux), using the program's Load atoms (chem.shift) [lc] command.

If you do not have access to XEASY, you can also open a PROT file in any text editor, to view the atom list it contains.
