  • bash shell question

    I tried to do a simple task in batch--unzipping many gz files. I have many .gz files, but how come it only unzipped one file then finished? Anything wrong with my script? thanks. John


    ## unzip fastq.gz
    for i in *.fastq.gz
    do
    #echo $i
    zcat "$i" > "${i%.*}"
    done

    have you tried 'gunzip *.fastq.gz' ?

      gunzip *.fastq.gz will delete original gz files. i want to keep original files.

        for i in `ls *.fastq.gz`; do gunzip -c $i > $i.fastq; done

          I tried
          for i in `ls *.fastq.gz`; do gunzip -c $i > ${i%.gz}; done

          still only unzipped just first file then finished. no error. very strange.

            I tested your version of the command and it worked fine. It could be something related to permissions.

              thanks. I thought it might be related to something internal. will find out.

                for i in $(ls *.gz); do sn=`echo $i | sed 's/\.gz$//'`; zcat $i > $sn; done;

                  another nice way to do it.

                  I really think something is going on with my server. It still finished after doing one file. I will ask my admin tomorrow. Will let you know.

                  By any chance did this happen to any one of you here?

                    Essential Discoveries and Tools in Epitranscriptomics
                    by seqadmin


                    The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist on Modified Bases...

                    Current Approaches to Protein Sequencing
                    by seqadmin


                    Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...
