I think that you can go to NCBI Sequence Read Archive (http://www.ncbi.nlm.nih.gov/sra/) to find out the public domain dataset.

This is one I find in the SRA (http://www.ncbi.nlm.nih.gov/sra/SRX106107).

I recommend you using "solid, miRNA" as keywords to search.

Hope my suggestion helpful.

In addition, you can also reach this web site (http://sra.dbcls.jp/?lang=en) in Japan for more dataset.

@ Yu-Feng Huang,

Thank you very much for your answer.....its really great source. but the problem is that i need small RNA upto only T/C35 bp long only .....and what you have provided (both) link...where only prsent data for ABI 4, 50bp long smallRNAs not for ABI 5, 35bp(with 3' adpater).

thank you once again and looking forward for your input.

@ Rupesh Kumar Kesharwani,

Is it possible to trim a read by length from 50 bp into 35 bp for testing your pipeline? In addition, it is hard to find library sequenced by ABI SOLiD 5500. However, it is lucky that I find the website http://gbnci.abcc.ncifcrf.gov/sra/index.php that has friendly search UI to meet your requirement. Hope this information helpful.

@ Yu-Feng Huang,

Thank you sir for your kind help...
