PEER REVIEWER COMMENTS: 
GENERAL COMMENTS: 
This is a letter to editor; the authors have certain good points to highlight, but
some others sounded like overcriticizing the authors of the original paper.
REQUESTED REVISIONS: 
Some good points raised by authors in this letter to editor about the original
paper; however, overcriticizing a previous paper, mentioning that the methods
are overall unclear, is not convenient to be published as a letter to the editor. In
addition, doubting the results/conclusion in the original paper did not sound
constructive for researchers and readers.
