No I believe there isn't sth like that. It should be a simple perl script to get that info or linux grep would help

Thanks Kevin - that might work - collapse sequences and then grab the sequence names using "select" (under filter and sort tools). Is there a way to "loop" such a search in order to go through the lines of a long file? I assume there must be something in the workflows but I have never used that feature.

Thanks

Hi Daniel, You would have multiple names for each sequence and that would be quite hard to display. I am sure someone thought through this. Since the sequence is the same, you can use the sequence to look back in the fastq file for read name. Although I am not sure how that would help you?

Cheers Kevin

Thanks Kevin. However, the collapse sequences replaces the original name of the sequences with a numerical code, and I need to keep the original names. Any other suggestions?

Thanks

Hi Daniel for 2) you may use the tools under NGS QC and manipulation FASTQ to FASTAhttp://main.g2.bx.psu.edu/tool_runner?tool_id=cshl_fastq_to_fastaconverter

For 1) you may refer to Simulated Dataset of Solexa - SEQanswershttp://seqanswers.com/forums/showthread.php?t=806

Has anyone replied you for 2) ?

Hello,

I have two questions - I apologize if they are trivial..

1. I want to simulate the amount of Illumina sequencing needed to

sequence and assemble a known genome. Is there a way to randomly pick sequences of a specific length from a genome (either one available online or one I upload)? Something like "pick 100bp randomly (either strand), move 400-500bp forward and pick another 100bp?"

2. Is there a way to remove redundant sequences from a FASTA file

without losing the original sequence names (as happens with "collapse")?

Thanks

Daniel
