Hi Mike,
I was able to select fastqsanger files from one of my histories at our public server. If you are using the public server, can you share your history with me and I will check if there is a reason you are unable to select these datasets. If you are trying this on your local instance, can you make sure it is running up-to-date Galaxy code?
Thanks for using Galaxy,
Dan

Dear Peter,
Thanks for the quick reply. But yes, the groomer output was marked as fastqsanger. I changed to generic fastq and back and it didn't work either way. I only get the fasta files from my history as possible input files. However, using the local installation via command line seemed to work (fastx_clipper -a TGGAATTCTCGGGTGCCAAGG -l 15 -n -v -i s_1_sequence.txt -o s_1_sequence_clipped.txt)
Kind regards,
Mike

Hi List,
I have a couple of miRNA-Seq files (Illumina GAIIx, 29nt read length). These reads contain differing amounts of 3' adapter sequences and therefore map really badly to the human genome (with eland v2). Therefore, I'd like to use the FastX clipper tool, which states that "This tool clips adapters from the 3'-end of the sequences in a FASTA/FASTQ file." However, After uploading my fastq files and converting it to Sanger format, the clipper does not accept the fastq file as input. After converting it to fasta it works fine. However, the mapping tools will only accept fastq files. So my question is, is there a way to clip the adapter directly in the fastq file (we have a local installation of galaxy, so I may also use command line options)?
Thank you very much for your input,
Mike
Hi Mike,
Is your input FASTQ file definitely marked as type fastqsanger (not just fastq)?
The fasta_clipper.xml says it will take fasta,fastqsanger,fastqsolexa,fastqillumina and is (now) aware that it should use the -Q 33 switch on Sanger FASTQ, see: https://bitbucket.org/galaxy/galaxy-central/src/default/tools/fastx_toolkit/...
Notice however that it does not accept the generic "fastq" Galaxy format (which I think would also include color-space FASTQ).
