When putting such a command into MEME:

meme *.fa -maxsize 1000000 -dna -minw 8 -maxw 25 -nmotifs 1

It splits up what its looking for into 8, 11, 15, 21 and 25

My question is whether it is looking between those sizes for any motifs that range lets say between 11 and 15 or only looking for those that are 11 and 15 nucleotides in length?

Thanks.
