    how to trim solid reads length?

    are there any tools available to trim solid reads length? for example, I want to extract first 30bp.
    Thanks!

    No tools that I know of. Both Emboss and Galaxy do not seem to have a way (although there are so many programs in both that it is hard to tell.) Trimming is trivial to do in perl or another language. If you are a "layer 3" bioinformatics person (see http://www.homolog.us/blogs/?p=85) then it will take less time to write the program than to respond back to this message. :-)

      OK, I wrote one, but not so fast, that's why I ask here to check whether there is some tool to do it already.

        I've managed to do it by double-encoding, passing through the fastx-toolkit, then reversing the double-encoding.

          Are there any new ways to do this?

            I don't understand. "trim" = cut ? zurechtstutzen
            Nor do I know/understand Emboss,Galaxy,layer 3,
            double-encoding,fastx.
            I just feel, there must be something wrong with bioinformatics,
            if cutting the length of a sequence gets a thread here.

              Let's reiterate what westerman said:

              Or, for that matter, reading through all the posts in this thread, then asking if anyone has thought up their new favourite way to trim reads to a particular length.

                  Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
                  by SEQadmin2



                  CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

                  Despite this, “CRISPR helped turn genome editing from a specialized technique into

                  Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
                  by SEQadmin2


                  Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

                  Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
                  by SEQadmin2



                  Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.
