我正在尝试运行这个命令
sh bbmap/bbduk.sh in1=fastq/Brca1Reads_ALL.1.fastq out1=fastq/Brca1Reads_ALL.1.TRIMMED.fastq ref=bbmap/resources/adapters.fa
在终端上，但我不断收到：
sh: 0: Can't open bbmap/bbduk.sh
我也无法直接用终端打开 bbduk.sh。我试过 chmod，从主文件夹授予权限，但似乎没有任何效果。
我尝试使用 bash，但它给出了no such file or directory。Rannamei -l bbmap/bbduk.sh并给出：
f: bbmap/bbduk.sh
drwxrwxr-x rizwan rizwan bbmap
-rwxrwxr-x rizwan rizwan bbduk.sh
cat 后面的几行是：
#!/bin/bash
usage(){
echo "

Description: Compares reads to the kmers in a reference dataset, optionally
allowing an edit distance. Splits the reads into two outputs - those that
match the reference, and those that don't. Can also trim (remove) the matching
parts of the reads rather than binning the reads.
Please read bbmap/docs/guides/BBDukGuide.txt for more information.
Usage: bbduk.sh in=<input file> out=<output file> ref=<contaminant files>
Input may be stdin or a fasta or fastq file, compressed or uncompressed.
If you pipe via stdin/stdout, please include the file type; e.g. for gzipped
fasta input, set in=stdin.fa.gz
Input parameters:
in=<file> Main input. in=stdin.fq will pipe from stdin.
in2=<file> Input for 2nd read of pairs in a different file.
ref=<file,file> Comma-delimited list of reference files.
In addition to filenames, you may also use the keywords:
adapters, artifacts, phix, lambda, pjet, mtst, kapa
literal=<seq,seq> Comma-delimited list of literal reference sequences.
touppercase=f (tuc) Change all bases upper-case.
interleaved=auto (int) t/f overrides interleaved autodetection.
qin=auto Input quality offset: 33 (Sanger), 64, or auto.
reads=-1 If positive, quit after processing X reads or pairs.
copyundefined=f (cu) Process non-AGCT IUPAC reference bases by making all
possible unambiguous copies. Intended for short motifs
or adapter barcodes, as time/memory use is exponential.
samplerate=1 Set lower to only process a fraction of input reads.
samref=<file> Optional reference fasta for processing sam files.
