You can just change the format of the data from fastq to fastqsanger if you're sure about the error format (use the pencil, then datatype tab) note: fastqsanger !=fastqcsanger

Hi Alex

 

Now is an another problem. I now deal with two fastq files, there are Illumina enconding 1.8 and pair-end, so I don't need to groom. But the fact is, I need to use the "filter by quality" and "Fastq interlacer" and without groom thses two tools can not regonize the files. Any idea to solve this problem?

It seems old Illumina encoding 1.5

So yes some tools requiring the fastqsanger would need grooming.

If you are up to programming you can seriously speed this up by using a precalculated transfer or hash table.

That way you do not have to do any calculation but just translate each quality line using generic regexp/grep/sed like tools or $seq =~ t/STARTSCORES/SANGERSCORES/g in perl.

The wiki table could be an alternative option. You still have to set the upload type to fastsanger likely since it will probably sniff the header and see its fastq but not 1.8+ encoding.



Good luck!

Alex

Hi Alex

I look the page of wikipedia, but I have a little confused. We sequenced with solexa. I paste a read of my data, can you tell me whether I need run Groom?
The read is like this:@HWUSI-EAS1734_0003_FC620JEAAXX:8:1:1174:9013#0/1

Hi

I presume the best way to optimise your current problem is to evaluate whether you really need to groom your data!? If its old data presumably yes, but if it is recent data in Illumina 1.8+ encoding(http://en.wikipedia.org/wiki/FASTQ_format) it is not necessary.... speedup 100% :-)
Groom would take long at our servers as well but due to the new Illumina format we didn’t bother to optimise it further by parallelisation for instance...

Hi，

I read the page of the document. But I don't think there is anything I need. Now, I installed a local instance of galaxy, and I just run it on a PC. I need to deal with large data, if I just use the default configure of galaxy, every task would take long time. For example I ran the FASTQ Groomer with a large file, the precedure is so slow, and galaxy would not use the potential of my machine. So I want to know how can I get galaxy ran faster. I already can upload files quickly and I just need to know how to ran tools quickly.

Hi,

This is a pretty broad question.  However, I would recommend that you start at:
