IEEE ISBI referencing

I am trying to reference as follows:

Search papers in google scholar, then click ‘cite’ and select BibTeX option.
Copy this code into a .bib file in latex.

I have downloaded a template for the paper from http://2020.biomedicalimaging.org/full-paper-instructions, where there is a IEEEbib.bst file. (bibliography style)

Call the following commands at the end of my paper:

bibliographystyle{IEEEbib}
bibliography{dong,mrf,davies,scheffler,bloch}

where my reference files are called dong.bib, mrf.bib, etc.

However when I do this none of the references materialise and I get this error message:

There are no entries found in a list you have created. Make sure you label list entries using the item command, and that you have not used a list inside a table.

Any suggestions?
