By mistake the SFF file was deleted once the Amplicon Full processing pipeline was done. How can we reprocess the data to generate the SFF file back again?
Thanks!
Thanks!

Sadly the gsReporter application will not produce SFF files from an exiting analysis directory; SFF files can only be generated by gsRunProcessor. But you don't have to repeat the entire Signal Processing pipeline, you can perform an Analysis Filter job on the existing D_ directory which will take far less time.Originally posted by Xterra View Post
If you are unfamiliar with how to perform a Filter only analysis (these steps assume your current working directory to be the run (R_) directory and the Full Amplicon analysis directory (D_) still exists there):
1. Create a template file with the default amplicon filter settings, saving it to a file named (e.g.) ampliconFilter.xml:
2. Run the filter only analysis pipeline providing the name of the template file you just generated and the existing analysis (D_) direcotry.Code:# gsRunProcessor --template=filterOnlyAmplicon > ampliconFilter.xml
The filter only pipeline runs much faster than the full analysis pipeline. You will have a new, complete D_ directory with the SFF files.Code:# runAnalysisFilter --pipe=./ampliconFilter.xml <D_directory_name>

I actually did exactly what you suggested but the new D directory did not included the SFF file on the regions subfolder.Comment

The SFF files are not in the regions subfolder. There should be a separate subdirectory named 'sff'.Originally posted by Xterra View PostComment

Sorry that's what I meant. Now, I am not quite sure what's going on, I repeated the process three time and I finally got the SFF file. However, when I split the MID, I can see I got very few reads/MID. When I split the original SFF file that came out of the run, I had plenty of reads per MID. Therefore, something is wrong.
Now, I can see the fasta and qual files, can I split the MID from the fasta file using any of the SFF tools?Last edited by Xterra; 10-31-2011, 08:19 AM.Comment

Why do want to do that? You should investigate on what is going wrong with your filtering job ...Originally posted by Xterra View Post

At this point I am more interested on retrieving my data.
Do you know of any tool I can use to split the MID using the central FASTA file that was generated during the run?Comment

You finally will need to find out what was wrong, believe me ... :-)
Nevertheless, one of the tools capable of doing what you want might be "FASTX Barcode Splitter" from the fastx toolkit (http://hannonlab.cshl.edu/fastx_tool...splitter_usage).

Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...Yesterday, 09:55 AM -
Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.
We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing...
