  • random downloading of .sff file

    I already have .sff file but I guess that is corrupted but still I want to check that whether my software is able to import .sff file or not....

    I am working on geneious software. So, I have tried a lot to download any random file in .sff format so that I can try to import in geneious but I didn't get it from anywhere.

    I guess you would like to download example SFF files. The IonCommunity has some test data for IonTorrent.

      I did try in this community but sadly I didn't get any kind of .sff file...

        Two years ago I had downloaded SFF files from the community. It was a part of a grand challange.

            You should be able to find SFF files on NCBI-SRA. http://www.ncbi.nlm.nih.gov/sra They will be in SRA format (search for 454 datasets). You will then have to convert them into SFF.

              For the general ability to read SFF files you should ask the support team of your software and/or look at their website and have a look at the manual.

              To check if your SFF file is corrupt you can either

              a) use 'strings' and see if the file ends with readnames
              b) use sffinfo from the Roche SFF Tools to see, if the file can be read/parsed. If not, you'll get an error and you can be sure that your file is corrupted (as the SFF Tools are definitely able to read SFF files :-) )

                Hi,

                In case you don't mind them being generated by a simulation software, I've recently uploaded many 454Sim-generated SFFs under http://www.ibi.vu.nl/downloads/, see the section 454 data used in and the corresponding readme file.

                Cheers

                          Here is an example SFF file: http://www.ncbi.nlm.nih.gov/sra?term...0cluster_dbgap (click on the "size" to download).

                          As I said before this particular file will be in .sra format (which is a special format that SRA uses). You will have to use sff-dump program found in the SRA-toolkit: http://www.ncbi.nlm.nih.gov/Traces/s...?view=software to convert the .sra file to the original SFF format.

                              .. still wondering why you don't have a look at the manual and/or ask geneious support team ..

                                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...

                                Strategies for Sequencing Challenging Samples
                                by seqadmin


                                Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
