Thank you Bernard. I'd like to add that carving the density shown in a figure (especially without explicitly describing the carve radius used) is the moral equivalent of showing only 1mm of background above and below the band of interest in a western blot.

I would advise extreme care when employing such presentation features. They are useful for display purposes and only when their use is stated as such, but they also open a venue for cognitive biases. One might want to have a look at how creative use of these ‘blob’ features until things ‘suit’ can betray the true believer… http://www.ruppweb.org/cvs/br/rupp_2001_NSB_questions_BotA.pdf https://www.dropbox.com/s/iul2cjbuu4x2o9f/Hanson_2009_retraction_bot_nsmb0709-795.pdf?dl=0 Best, BR The first principle is that you must not fool yourself and you are the easiest person to fool.” Richard P.
