Hi all,
Does any one have (or galaxy team: are you planning to develop) tools for NCBI's SRA binary container format ?
For starters, a wrapper for the "fastq-dump" program that converts a lite-sra back to fastq ?
Just trying to avoid re-inverting a wheel, -gordon
Assaf:
We are getting multiple requests for this but did not have the bandwidth to do it. So if you are planning to implement - share through the toolshed and we will roll it to main.
Tx,
Anton

To start, this patch adds "SRA" binary type with sniffing and upload support: http://cancan.cshl.edu/labmembers/gordon/files/sra_binary_data_type.patch
It only adds the datatype to "datatypes_conf.xml.sample", so existing installations must manually add the following lines to their ""datatypes_conf.xml": <datatype extension="sra" type="galaxy.datatypes.binary:Sra" mimetype="application/octet-stream" display_in_upload="true"/>
and
<sniffer type="galaxy.datatypes.binary:Sra"/>
A question to people who are using "fastq-dump" on the command line: What are the most common parameters you're using ? I've heard about using Illumina or Sanger quality scale (-Q 64 / -Q 33), Minimal read length (-M), Clipping (-W), quality filtering (-E).
Suggestions are very welcomed.

Hi,

The way I got round this was let the SRA website do the conversion. So just paste in the URL in the upload screen:
http://trace.ncbi.nlm.nih.gov/Traces/sra/sra.cgi?cmd=dload&run_list=SRRX...
Where SRRXXXXXX is the archive of interest, and it downloads Sanger FASTQ sequences to Galaxy.
