Hello Weiping,
The resulting SAM hits can be converted to intervals, and the intervals
merged, and those regions extracted from the reference genome you mapped
to. The tools to use would be:
* NGS: SAM Tools -> Convert SAM to interval
* Operate on Genomic Intervals -> Merge (although you can explore other
tools in this group)
* Fetch Sequences -> Extract Genomic DNA
Note that this would not include any variation included in the original
mapped fastq data itself. If you are interested variation (SNPs or
Indels or both) in your data, then you want to use a mapping tool like
BWA (or Bowtie2 in a local or cloud Galaxy), followed by a variant
analysis tools. Several tool groups in the "NGS:*" section are for this
purpose, such as those in the group " NGS: SAM Tools" (Mpileup, etc.).
Hopefully this helps,
Jen

Hi all,
I would like to know if mapping reads to a reference genome, through
galaxy, can generate the query genome sequence?
I had mapped my reads from Illumina sequencer to a reference genome
through both BWA and Bowtie on Galaxy public server
platform(https://main.g2.bx.psu.edu/root ). As a result, i gained the
SAM files. But, i can't find how to generate the resulted assemblied
genome sequence.
Is there anyone know this? Any reply will be very appreciated.
Best regards.
