    MUltifasta file

    hi every one,

    what i need to do is i need multiple sequence alignment file

    i converted the vcf file to consensus fasta and "cat" all these consensus sequence into multifasta.



    in my cat file seq are >1......>10000 for a.fasta and >1......>10000 for b.fasta when i use clustal w it gives error that sequence have same header THAT MAKES SENSE so what i am planning to do is to convert >1..>2...>3.>10000 to >1

    and >1..>2..>3..>10000 for b.fasta to >2 and same for for all my 5 samples
    i have to use this file for multiple alignment
    Regards

    Do you want to know how to do the renaming or is this just an informational post?

      how i can convert
      >1...>2....>3...>10000 to >1

      and
      >1..>2..>3....>10000 for b.fasta to >2 and
      same for for all my 5 samples

        You want to convert every fasta ID header from multiple fasta sequences in file "a" to >1 and from file "b" to >2, is that correct?

          That won't give them unique deflines, which I think is what he/she is after for input to clustalw. I still can't tell what the problem is, though.

              If you rename all of them as >1 or >2 for a sample the sequences ID's would no longer be unique.

              What kind of MSA are you trying to do?

                i want all the genes e.g in sample 1 to be concatenated as >1 likewise for my all samples
                my thought is as all genes in all files are in same order so when i have multifasta as >1, >2, >3,>4,>5
                i will take that multifasta to do alignment around these interval

                  Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

                  I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

                  Here are nine questions we think about, in roughly the order they matter, before...
