  • Dialign2-2 outputs

    Hi,

    i am actually working with dialign2-2 et i have some problems with my alignments. I make pairwise alignment and i try to compare short DNA sequences (between 10 et 4000 nucleotides).

    When i use dialign i use -n to specify that i work on DNA sequences, but when i look at my output, i obtain better alignments using no option (in this case dialign considers that i work with proteins sequences).

    For example :

    input:
    Code:
    GGCGGGCCTCGCCCCGCGCTGTTCTTTCCTC[COLOR="Red"]C[/COLOR]CCC
    GGCGGGCCTCGCCCCGCGCTGTTCTTCCCAC[COLOR="Red"]T[/COLOR]CCC
    output using dialign2-2 -n file.fa :
    Code:
    GGCGGGCCTCGCCCCGCGCTGTTCTTTCCTC[COLOR="Red"]C[/COLOR]CCC
    GGCGGGCCTCGCCCCGCGCTGTTCTTCCCAC[COLOR="Red"]T[/COLOR]CCC
    and using this : dialign2-2 file.fa :
    Code:
    GGCGGGCCTCGCCCCGCGCTGTTCTTTCCTC[COLOR="Red"]-[/COLOR]CCC
    GGCGGGCCTCGCCCCGCGCTGTTCTTCCCAC[COLOR="Red"]t[/COLOR]CCC
    I have underline differences in red.



    Moreover, in several cases (always using -n), my output sequences are more longer than my input sequences (between 2 and 5 nucleotides). How can i obtain this difference ?

    Thanks

    And sorry for my english

    Resolved, my treshold was too low (T=0 per default)

      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...
