dry解析教本という本で自習中の初心者です。大学のMacでは出来たのに家のMacMiniだとエラーが出て、理由が分かりません。

SKMac-mini:expression SK$ tophat -p 1 -G Homo_sapiens/NCBI/build37.2/Annotation/Archives/archive-2014-06-02-13-47-29/Genes/genes.gtf -o tophat_results/ERR266337_P5 Homo_sapiens/NCBI/build37.2/Sequence/Bowtie2Index/genome ERR266337_trim.fastq

ところが今いるexpressionというディレクトリには確かにERR266337_trim.fastqが存在するはずだと思います。

SKMac-mini:expression SK$ ls ERR266335.fastq ERR266347.fastq ERR266351_trim.fastq  ERR266335_trim.fastq  ERR266347.fastq.gz FastQC ERR266337.fastq ERR266347_trim.fastq  Homo_sapiens ERR266337_trim.fastq  ERR266349.fastq Homo_sapiens_NCBI_build37.2.tar.gz ERR266338.fastq ERR266349_trim.fastq  tophat_results ERR266338_trim.fastq  ERR266351.fastq

このエラーはどうして出てきたのでしょう?ご助言がいただければ幸いです。

解決はしていませんが、1つわかったことがあります。1番目のサンプルは無事に解析できているようです。2番目のサンプルを解析しようとすると同じエラーがでました。2番目を諦めて3番目を解析しようとしても同じでした。前回の質問の後でディレクトリを変えて(expression->expression2)別のサンプルセットを解析しようとして気づきました。実は前回のサンプルセットでも1番目は解析できていたのです。2番目以降を解析しようとするとエラーが出ます。エラーメッセージはBiostarsのQuestion: Weird Tophat2 Error Message https://www.biostars.org/p/78628/ に似ている気はしています。
