# What is the meaning of this data from a protein data bank (PDB) file? [closed]

The following rows are part of a large dataset:

I know that the right-hand side real numbers are the distances between the C-alpha atoms in a beta-strand.

The data is from the PDB file of 16PK protein. However, it is formatted like this after download.

What do other column values mean?

What information does this data-set convey altogether?

• What the very first header row says ? It should be just 7 lines away. Jul 13, 2021 at 9:50
• Why don't you just download the .pdb and get the data you want directly from that? It will probably be quicker that way as these text files are easily edited. I just downloaded it and it seems quite normal. Jul 13, 2021 at 11:27
• This is an interesting puzzle but it would be more useful if you provided information about the origin of the data (what program generated it?). Jul 13, 2021 at 15:01
