well, I have watched few parts of the videos and havent gone through other two parts.
Actually when I am trying to run simple jobs from command line like

parallel 'samtools flagstat {}.bam >{}.bam.stats'

I am getting this message on scren

Academic tradition requires you to cite works you base your article on.
When using programs that use GNU Parallel to process data for publication
please cite:

O. Tange (2011): GNU Parallel - The Command-Line Power Tool,
;login: The USENIX Magazine, February 2011:42-47.

This helps funding further development; and it won't cost you a cent.
If you pay 10000 EUR you should feel free to use GNU Parallel without citing.

To silence the citation notice: run 'parallel --bibtex'.

parallel: Warning: Input is read from the terminal.
parallel: Warning: Only experts do this on purpose. Press CTRL-D to exit.

I dont understand whats happening here.

You probably meant something along the lines of:

parallel 'samtools flagstat {} > {}.stats' ::: *.bam
