    It may be more work than necessary to re-map the proteins back to the scaffolds and then parse the results to make the GFF file.
    Maker run took more than 2 weeks :-(

Output of maker was the predicted transcripts, prtoteins and their corresponding gff file. However, unfortunately we only have the predicted proteins now nad lost other files. Hence instead of running the time consuming Maker pipeline again, I was wondering is their a way of mapping/aligning the proteins aganist the genome just to create the gff file?

    You have not said anything about the size of the genome you are working with but you could perhaps use MAKER (http://gmod.org/wiki/MAKER) which will make GFF3 files.

    Otherwise you can build the file yourself by parsing the information you have to fit the GFF3 format: http://www.sequenceontology.org/gff3.shtml

    started a topic create the missing GFF

    create the missing GFF

    Hi,

    This could be a trivial question. I have a de novo assembled genome and predcited proteins in fasta format. However, the accompanying GFF files are missing. What's the best way of creating the GFF file? Is it: blast proteins vs genome and then something like blast2gff using the blast result?

    Thanks.

    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
