.sh 스크립트를 실행할 때 예기치 않은 표시 "(" 근처에서 구문 오류가 발생했습니다.

오류는 다음과 같습니다.

merge_star.sh: line 19: syntax error near unexpected token `('
merge_star.sh: line 19: `cat <(cat ~/asn_project/alignment_sorted/tmp/header.txt | sed 's/ /\t/g') ~/asn_project/alignment_sorted/tmp/tmp.out > ~/asn_project/alignment_sorted/STAR_counts.txt'

문제의 .sh 스크립트에 있는 줄은 다음과 같습니다.

cat <(cat ~/asn_project/alignment_sorted/tmp/header.txt | sed 's/ /\t/g') ~/asn_project/alignment_sorted/tmp/tmp.out > ~/asn_project/alignment_sorted/STAR_counts.txt

#!/bin/bash
# create header file
echo gene_name $(cd ~/asn_project/alignment_sorted && ls *_ReadsPerGene.out.tab | sed s/_ReadsPerGene.out.tab// | sort -u) > ~/asn_project/alignment_sorted/tmp/header.txt

# Place each sample's STAR gene count file - ReadsPerGene.out.tab in the tmp/ directory 
# The 2nd column (-f2) of ReadsPerGene.out.tab contains the non-stranded counts
for sample in $(cd ~/asn_project/alignment_sorted && ls *_ReadsPerGene.out.tab | sed s/_ReadsPerGene.out.tab// | sort -u)
do 
    echo ${sample}
    cat ~/asn_project/alignment_sorted/${sample}_ReadsPerGene.out.tab | tail -n +5 | cut -f2 > ~/asn_project/alignment_sorted/tmp/${sample}.count
done

# get a list of gene ids (-f1)
tail -n +5 ~/asn_project/alignment_sorted/N_1_ReadsPerGene.out.tab | cut -f1 > ~/asn_project/alignment_sorted/tmp/geneids.txt

# combine all the columns of the count files
paste ~/asn_project/alignment_sorted/tmp/geneids.txt ~/asn_project/alignment_sorted/tmp/*.count > ~/asn_project/alignment_sorted/tmp/tmp.out

# add the header
cat <(cat ~/asn_project/alignment_sorted/tmp/header.txt | sed 's/ /\t/g') ~/asn_project/alignment_sorted/tmp/tmp.out > ~/asn_project/alignment_sorted/STAR_counts.txt

# remove the tmp folder
rm -rf ~/asn_project/alignment_sorted/tmp

저는 .sh 스크립트 코딩을 처음 접했는데 어떤 오류를 수정해야 하는지 모르겠습니다. 도움을 주시면 감사하겠습니다.
