Illumina samplesheet fields

[nicolallias]

Hi there,

A samplesheet (for demultiplexer.pl) as the following headers:
FCID,Lane,SampleID,SampleRef,Index,Description,Control,Recipe,Operator

What is "Recipe" meaning ?

Thanks

When the techs start the sequencer they load a recipe - it's what tells the instrument how many cycles to run, etc. I don't believe it's required for the demultiplex.pl script. It's info that would have been generated if you used the cluster station/cBot to create the sample sheet.

Another difference – a fresh one – additionally comes into play whilst we remember fractional powers. Suppose that the fractional strength m/n has been decreased to lowest phrases (all commonplace place elements within side the numerator and therefore the denominator were cancelled). To calculate xm/n, we continue in steps: 1) stilleducation Find the n th root of x (x1/n = ); 2) Raise it to the m th strength. The 2d step is straightforward: we will boost any big variety to an integer strength. the primary step, however, is complex for poor x : We can’t meaningfully invite a good root of a poor big variety . Thus, the allowable inputs (domains) of fractional powers depend on whether or not n is even or bizarre.
