Analyzing Targeted Resequencing data with Galaxy
by Lali 05 Apr '11

05 Apr '11

Hi! I am having problems with my sequencing results, but I am a newbie at this; so I am thinking there is something wrong with my analysis. So far, I've tried Galaxy and CLC Workbench, but with CLC I could not align to the whole genome, only to individual chromosomes (maybe there is a way, but by the time the trial ended I had not found it). I used SureSelect capture kit and did single end sequencing on an Illumina. The files the lab sent me are FastQ Illumina 1.5 files, my samples were indexed, and I got a series of files each representing an Index. What would be the standard workflow for this kind of data? Which tools/settings? Does anyone have an example Galaxy workflow for preparing (clipping adapters, quality trimming) and mapping Targeted Resequencing Data? Is there a way to obtain a coverage report through Galaxy? Is it possible to ignore/discard the reads mapped when the coverage is below a certain threshold? I know, I know, a lot of things, but I am very lost. Any help is appreciated. L

You can do all the quality filtering with Galaxy, but may involve various manipulations of the data. If I am not mistaken the "metagenomics" workflow may help you out a little. Its designed for 454 data but should give you an idea of how to go about things. There is a video tutorial on the site for this workflow. A good place for you to start, however, may be here: Subject: http://edwards.sdsu.edu/prinseq_beta/# Prinseq is easy to use and will give you a full break down of your raw data and enables you to filter by quality/length etc. FASTqc is an Illumina specialized preliminary analysis tool: http://www.bioinformatics.bbsrc.ac.uk/projects/fastqc/ I my self was not very impressed with CLC at all. It lacks very rudimentary yet critical functions. I am currently working on population amplicon data so couldn't really help you too much in the latest mapping to reference advances, but I found the Lasergene SEQman mapping and de-nova assembler much better than the CLC assembler.

where to get indexes for mapping tools
by Yury Bukhman 04 Apr '11

04 Apr '11

Hi, we have set up a Galaxy server for internal use. We would like to provide indexes for NGS mapping tools for a set of organisms that are relevant to our research. While bowtie has a repository of such indexes, other tools, e.g. bwa, don't seem to have one, so we have to build our own. Is there a repository of pre-built indexes for all mapping tools supported by Galaxy somewhere? Thanks. Yury -- Yury V.

Hi, Are there any papers out there that have published links to Galaxy workflows that lets others run the workflows on new data or rerun the original analysis? Thanks -Surya
