Merit of best subset found & Methods

Hi

I am currently using the selection of WEKA attributes, however, I have a question regarding the "Merit of best subset found" parameter, since in several examples they fluctuate between 0 and 1, instead with my data and using the Wrapper method this value is triggered above 1. Is this OK?

My data contains 35 soil samples and for each sample I have the reflectivities values for each nm (400 - 2450 nm), in total 2051 columns. The attribute that I selected as class is of numeric type, which corresponds to the different results of the chemical analyzes (for example As, Cd, Cr, etc). What method and evaluator do you recommend I use?

I have planned to do the same for my vegetation samples, but these are much smaller, there are a total of 16 vegetation samples, I don't know if I would have any problem applying the Wrapper method or which one could apply?

Regards
