  • Looking for Annotation software

    At the moment i have more or less a chloroplast genome assembled. What i could do now is get al the ORF's and blast it and obtain the names by using for example BLAST2GO. The problems i am facing with that is when i take a ORF it might also be present somewhere else. And when i realign the results back it does not match the region i had before. ( Can do it all 1 by one but that will take ages!)

    My question is now is the following possible:

    Give a program the chloroplast sequence in fasta.

    Let the program look for ORF's

    Blast the ORF's and annotate the location

    Send me the file.

    Thanks for the help

    Have you tried Artemis.
    It can detect ORF and annotate them and can read .bam file

      Thanks im looking into it at the moment. But does this program need a database located at our place or is NCBI also possible for mass blasting of all the ORF's and annotation. Still reading the manual though

        I've done this kind of workflow with Python scripts: take FASTA genome, find ORFs, BLAST them, produce a crudely annotated GenBank or EMBL file, give this to our Biologists to look at in Artemis or their tool of choice. This gives me the freedom to tweak everything (for example how to handle alternative start codons, which BLAST database to use, etc).

          Maybe this previous thread could help

            Through artemis i got the ORF's and through Run > Pfam Search i get the correct name for the ORF. But how to do this for all my ORF's and automatically?

            Found the readme.. (my bad)

            Searching and Using Local Sequence Databases (Optional)

            Will look into that

            Downloaded all the blast software and placed it in the package dir from Artemis.

            But when i use the GUI in the mac environment, select the ORF's, Run fasta on selected future against %uniprot it gives me the login screen... I hoped i could make a link against the NCBI database but is this even possible cause i dont have any data myself because this is a "new" species we are working on

              Essential Discoveries and Tools in Epitranscriptomics
              by seqadmin




              The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...

              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...
