Dna Sequencers 150 Bps Output File

I am doing some experiment using BowTie which is a short read aligner that aligns short DNA sequences (reads) to the human genome. Now, I want, to experiment with it on 150 bps reads. So, I want DNA sequencers 150 bps output file. For example, output of this (Genome Analyzer IIx). Can anybody please help me, where can I find it ? Or is there any BioInfo community who can help me about this ?

Are you just looking for raw sequencing reads? If so: Short Read Archive should have what you want.

SRA

The main page states:

The Sequence Read Archive (SRA) stores raw sequencing data from the next generation of sequencing platforms including Roche 454 GS System®, Illumina Genome Analyzer®, Applied Biosystems SOLiD® System, Helicos Heliscope®, Complete Genomics®, and Pacific Biosciences SMRT®.

One example experiment:

data

The Short Read Archive contains FASTQ data. They have a conversion script to dump SRA to FASTQ.

Thanks a lot. But, I really don't find any folder saying that they contains, 150 bps length Short Read.

see changes to main post above.

Well you could look in the European Nucleotide Archive (ENA). From a quick query ENA contains a number of sequencing runs produced using the Genome Analyzer IIx ("instrument_model=Illumina Genome Analyzer IIx"), so they would be a place to start.

The ENA provide Web Services (see http://www.ebi.ac.uk/ena/about/browser), and the experiment meta-data is available so you can automate your search for appropriate experiments, and fetch the referenced FASTAQ data from the FTP site.
