    Thanks @kmcarr, this looks indeed nice too but will require some setup to bring the two entities to life. I should look at this once but my small needs are satisfied with the simplistic multifasta query together with some more stringent filtering to have only one hit per bait.

    Code:
    -stepSize=5 -repMatch=2253 -minIdentity=98 -maxGap=0

    Another option is to use the gfServer/gfClient programs which are part of BLAT. The gfServer program maintains the genome index in memory and gfClient submits BLAT queries to the gfServer. While the primary use case may be for the server and client to be on different hosts (or one server handling many clients) there is no reason they can not be run on the same computer.

    And the winner is ....
    put all queries in a single multifasta.
    so simple I did not think about it.

    shame on me :-(

  • keep .2bit reference in memory during batch blat jobs

    I succeeded to run a single blat search with standalone blat installed but would like to reduce the time of loading the reference each time when doing consecutive searches from a list of queries.

    Can I by some magic keep the .2bit genome in memory
    Here is my single command

    Code:
    blat -stepSize=5 -repMatch=2253 -minScore=0 -minIdentity=0 \
       ref/hg19.2bit query.dna \
       -ooc=ref/11.ooc \
        out.psl
    Loaded 3137161264 letters in 93 sequences
    Searched 50 bases in 1 sequences
    Thanks in advance

    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
