    I wouldn't align with Excel .... scripts are very slow in it, and I doubt you'll find a bioinformatician willing to touch it!

    Why not try muscle, thats a nice quick bit of software. Perhaps muscle can also align cysteines only, with the gap characters (-) you put in. Otherwise maybe subsitute all other amino acids with a fairly neutral amino acid (perhaps Alanine). You can then see if the alignment is mainly determined by the cysteines.

      Hello,

      Excel for storing sequence data and/or VBA for scripting is a very bad idea in this context.

      Try the following:
      Convert your sequences to Fasta format (plain text) and use either Muscle (muscle -maxiters 1 -in your-fasta-file) or Mafft (mafft -auto your-fasta-file)

        I also suggest Muscle http://www.drive5.com/muscle/

          Recent Advances in Sequencing Analysis Tools
          by seqadmin


          The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

          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...
