Appendix I: Exchange between us and Wang et al. in June 2012


Posted on July 20, 2014


In June 2012, we received a comment by Wang et al. criticizing our paper [Nature 483, 444-447 (2012)]. By using some very preliminary numerical simulations, they claimed that “there seems no advantage of the equal slope tomography (EST) method over simultaneous algebraic reconstruction technique (SART).” After carefully studying their comment, we found that Wang et al. were scientifically unethical in their data analysis. Specifically, Wang et al. drew a conclusion based on their very preliminary simulations, while completely ignoring the more rigorous experimental results published in 2008 [J. Struct. Biol. 164, 221-227 (2008)], in which we clearly show that EST consistently outperforms SART. Furthermore, Wang’s conclusion was based on a misleading comparison between two data sets at different conditions: 55 projections with EST vs. 69 projections with SART. We notified Nature of this and Wang et al. then stopped submission of that comment. Below are Wang’s comment and our response.
