hisat2 SyntaxError: invalid syntax

Hi all,

I am really struggling with hisat2 recently and getting confused. I’m trying to run hisat2:

hisat2 -t -p 2 -x shiryn RNAseq data/reference/grch38_genome/grch38 -1 shiryn RNAseq data/trimmed data/ly1_paired_1.trim.fq.gz shiryn RNAseq data/trimmed data/ly1_paired_2.trim.fq.gz -S shiryn RNAseq data/alighed/ly1.sam

This is my error:

File "/home/yun/Downloads/hisat2-2.2.0/hisat2_read_statistics.py", line 182
length_map = sorted(length_map.iteritems(), key=lambda (k,v):(v,k), reverse=True)
                                                       ^

Any help is appreciated!
