Errors in sorting

Hello, I'm getting the following error when run soapsnp:

My command line is the following: ./soapsnp -i '/home/me/SNP/Programs/soap2.21release/alinhamento chrN/teste4' -d '/home/me/SNP/Programs/soap2.21release/Reference genome/todos_um_e_dois.fasta' -o /home/me/SNP/Programs/soap2.21release/teste4consensus -r 0.05 -t -u -L 400 -M /home/me/SNP/Programs/soap2.21release/teste4matrix -m

How do I solve this issue?
