  • minimus2 woes

    I'm trying to merge an alignment to a reference sequence and a de novo assembly using the same Illumina reads. It seems like minimus2 would be the right tool for the job, but every time I run it I get no overlaps and all the sequences just dump into singletons.seq. Just as a test, I tried assembling the alignment contigs to themselves (i.e. made a file with two copies of the alignment contigs, then performed alignment with minimus2) and again got no overlaps and all singletons!

    I'm already a little wary of this program since I had to go in and modify it for myself just to get it to run (I kept getting usage errors on dumpreads steps 12 and 13 until I moved $(BANK) after the -m/M options instead of before), but that's the only change I made. Is there some other glitch I don't know about?

    Any suggestions?

    Full disclosure: I didn't install qt3 when I installed amos since it wouldn't compile on OSX 10.6, but my impression is that's just for the viewers and minimus shouldn't depend on it.

    Thanks.

    Never mind. I fixed it. It seems that at the ovl2OVL step (step 23), the output AMOS ovl file was empty. When I changed the extension of the AMOS ovl output file in minimus2 from .OVL to .ovl2, the output was no longer empty and the program (finally) worked like a charm. Maybe it's a Mac thing. I don't know, I'm just glad it's working. Sorry for for clogging up the forum here, but maybe my trial and error process can save somebody else some time and aggravation someday...

        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...
