scrappie fasta Illegal instruction

[chilampoon]

Hello! I am new to nanopore signal processings and I was trying to run the MotifSeq in SquiggleKit. However each time I ran scrappie scrappie squiggle my_kmer.fa > scrappie_kmer.model I just got the Illegal instruction message. Also scrappie is deprecated, is there any replacement for it? Thanks.
