raw sequencing data

Question

[Tasneem Fetian]

Where could I get raw data of illumina DNA sequncing? in BAM,SAM or fastQ format. Is there any kind of online free database for such a thing.

for optimization and testing purposes, I need data of both, good and bad quality to feed it into a pipeline I am working on.

NCBI SRA is the main repository for raw sequence data. It will be in fastq format. There may be some aligned data available there but that would be in much smaller numbers.

The data is generally replicated at EBI-ENA and DNA bank of Japan (DDBJ).

Note: Most of the data should be available freely. Certain types of data (e.g. human datasets from some projects) require additional approval.
