    Currently there are no plans multithreading the existing tools -- what I am saying is that there might be new tools using that option if they use multithreading -- sorry if my comment was misleading

    Thanks, I suddenly realized.

    I thought '-j' is an option of 'gt' command that can be added into all gt tools. Maybe I was so naive for it can only added into the command of 'gt ltrdigest'.

    It is really awesome. I know what to do next, thanks!

Depending on what task you are trying accomplish, there are ways of running jobs in parallel but I'm not aware of any genometools applications that will use multiple processors.
    I saw '-j' in LTRdigest User’s Manual where write:
    To run the protein domain search in a parallel fashion, use the -j parameter to gt to specify the number of concurrent threads to use:
    gt -j 3 ltrdigest [options] GFF3 file indexname
    I thought '-j' is an option of 'gt' command that can be added into all gt tools. Maybe I was so naive for it can only added into the command of 'gt ltrdigest'.

    When running:

    It simply used one cpu and was quite slow. Then I tried:
    $ gt -j 4 suffixerator ...
    But nothing changed.
    So I'm really confused whether gt could use parallel processors to accelerate working, just like RepeatMasker (who has -pa to set number of parallel processors)?

    The Impact of AI in Genomic Medicine
    by seqadmin



    Artificial intelligence (AI) has evolved from a futuristic vision to a mainstream technology, highlighted by the introduction of tools like OpenAI's ChatGPT and Google's Gemini. In recent years, AI has become increasingly integrated into the field of genomics. This integration has enabled new scientific discoveries while simultaneously raising important ethical questions1. Interviews with two researchers at the center of this intersection provide insightful perspectives into...

    Multiomics Techniques Advancing Disease Research
    by seqadmin


    New and advanced multiomics tools and technologies have opened new avenues of research and markedly enhanced various disciplines such as disease research and precision medicine1. The practice of merging diverse data from various ‘omes increasingly provides a more holistic understanding of biological systems. As Maddison Masaeli, Co-Founder and CEO at Deepcell, aptly noted, “You can't explain biology in its complex form with one modality.”

    A major leap in the field has
