in reply to How to use Convert::ASN1 ?

Do you know what your example data is/represents/contains? Do you have an ASN1 decription of it?

    This is file description: 
    The format of a Tag is as follow:
                       Identifr    Filler    Length    Data
Where 
      Identifier : A 3 bytes long number uniquely identifies the Tag
      Filler     : A filler of with value H’81 is inserted at position
+ on condition number of data bytes sent in the AXE signal is odd. 
      Length     : is the number of  taaged data in bytes.
      Data       : is the actual data in the tag

      Wherever you are obtaining your ASN.1 dataset, should also supply you with or make available to you, an ASN.1 description (template) of the format of the data within that dataset.

      For example, if you are downloading .aso files from NCBI, then somewhere within their site/ftp there will be a file containing the ASN.1 description that looks something like this one. In that same directory there are several other .prt files, one of which would form the the input to Convert::ASN1 (or possibly better, Bio::ASN1::Sequence), if they are the source of your dataset.

      Reverse engineering an ASN.1 description based upon the limited information you've provided above (where did that come from?) is iffy at best.
