    Did you replace "filename.sff" with the real file name when you ran the command? Or is your file actually named "filename.sff"?

    Code:
    $ strings your_actual_file_name.sff | grep run_type
    Can you post the size of the SFF file?

    Code:
    $ ls -lh your_actual_file_name.sff

      yeah I typed my real file name in the place of filename, and size of the file is 607.1 mb

          So the size looks decent for a SFF file (recollecting from distant past, have not dealt with 454 data for a long while).

          Do we have any additional information beyond where we left things off last night?

          I have not used this program before but it seems to be able to use SFF files. Do you want to see if your file will work with this: http://www.dnabaser.com/download/SFF%20tools/

                If that is the case then there is a distinct possibility that your SFF file is corrupt. Is there any chance that you can go back to whoever generated the data and ask for a fresh copy?

                  BTW: Can you edit the title of this thread (and keywords if you had put in any) in the first post? This thread is not related to illumina sequencing and it will show up in future searches.

                      You will have to choose "edit" and then "Go Advanced" to be able to edit the title.

                              Well, you have a SFF file with a missing manifest. Probably corrupted.

                              Again, ask your PI for the "complete" dataset. There went probably something wrong during transfer. For the SFF file check the MD5 sum before and after copy process, just to be sure, that it has been transferred completely.

                              And, yes, it seems that geneious does not support native SFF import :-(
                              But if you have the complete dataset you can just use use the fna/qual pair (always use the quality files if available), just as intented from the very beginning :-)

                              But of course, you can have a look at "sff_extract" or Roche's "SFF Tools" just to be able to deal with SFF files on the command line.

                              regards.

                                  Nine Things a Sample Prep Scientist Thinks About Before Sequencing
                                  by SEQadmin2


                                  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...

                                  From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
                                  by SEQadmin2


                                  Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


                                  The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
