Import errors

When SeqVerter imports sequences, it identifies the file format automatically.  Occasionally, problems may arise resulting from incorrect format identification.

Common problems include:

  • SeqVerter does not correctly identify plain text sequences.  If you import plain text (unformatted) sequence data, the file will be opened, but no sequences will be imported.
  • To avoid this problem, open the file with a text editor such as Notepad, and add a FASTA-style definition line.  For example, if the sequence name was "myseq", add the line ">myseq" as the first line of your file.
  • The second problem you may encounter occurs when you try to import a file with a disallowed file extension.  For example, SeqVerter will not open files with extensions such as .JPG, .EXE, or .DLL.  If you try to open a sequence with such an extension, an error message will be displayed.
  • If this happens, you will need to change the file extension using the Windows explorer.
  • SeqVerter may open a binary file that is not a sequence file.  When this happens, the sequence names and data will appear to be random ASCII characters.
