    separating indexed and nonindex sequences

    Hello,

    I have paired end Illumina sequences s_1_1_sequnece.txt and s_1_2_sequence.txt. These sequence files included indexed and nonindexed reads. When I tried to separate the sequence file one by one, I found the numbers of sequences in indexed and nonindexed files for one of the pair are different from the numbers for the other of the pair. So I need scripts to open the two files and check the pattern matching the reads in both files and pick them out from both files.

    My scripts to open to files got memory problem.I am not good at perl. I am wondering who has any easy or efficiency way to separate the indexed and nonindexed sequences for both of paired sequence files together?

    Any suggestions or comments are absolutely appreciated.

    Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

    Nine Things a Sample Prep Scientist Thinks About Before Sequencing

    I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

    Here are nine questions we think about, in roughly the order they matter, before...
