    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/

          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 on Modified Bases...

          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...
