  • file format headaches - producing interleaved fastq

    Hi

    I have a load of paired end solid data as .csfasta and .qual files. I need to produce an interleaved fastq file from these for input into e.g. BFAST. Ideally I would also like to be able to produce a fastq file per read for properly paired mates and a third file of orphaned (single end) reads for use with e.g. Bowtie.

    Can anyone point me to an existing script to do this or will I need to write one? I have looked at some existing options e.g. the Galaxy python solid2fastq script but so far I haven't managed to get it to output anything more than zero byte files. It also doesn't output the orphaned reads and re-scales everything to phred33, which is not always desirable.

    I need to do the same for Illumina data as well, so if there is an option that also handles Illumina data (or is specific to it), that would be great.

    Galaxy solid2fastq.py

    I figured out why I was getting zero byte outputs from the Galaxy python script. It seems that for paired end input you HAVE to specify '-t true' because otherwise the name matching fails for every read. Obvious after some staring at the code but not otherwise.

    So, now I still need to output the orphaned reads and a method to do the same for Illumina data.

      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...

      Strategies for Sequencing Challenging Samples
      by seqadmin


      Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
