Wrong morphometrics values? #272

Closed cpavloud closed 8 months ago

cpavloud commented 10 months ago

Hello, I am using rfishbase 4.1.2 in R version 4.1.1. I have a list of species names and I am retrieving their morphometrics using

all_fish_Aphia_morphometrics <- morphometrics(species_list = all_fish_Aphia$scientificName)

However, the values I get are totally different from the ones in the actual fishbase website. Do you have any idea why this might be happening? I have attached some screenshots in case they will help.

Ok, I just found out that the values are provided in pixels and not in cm... Would it be possible to retrieve the original cm values?

pixels

these would be good questions to ask the FishBase team. rfishbase can only access data made available in fishbase. if fishbase provides some length measurements in pixels, I very much doubt those were converted from 'original cm' values, but guessing that the photograph scale may not have been available, but still useful in determining the relative lengths shown.
