AnalyzeFractionsApp

AnalyzeFractionsApp[chromData]⟹pickedSamples

selects fractions from a given chromatograph to be carried forward for further analysis.

AnalyzeFractionsApp[chromProtocol]⟹{pickedSamples..}

analyzes all data in the given protocol.

AnalyzeFractionsApp[collectedFracs]⟹pickedSamples

uses the given set of fractions as a starting point for the analysis, instead of starting by filtering based on peaks.

Details

The selection process first filters using the Peaks options, then filters against the Exclude option, and finally filters on the Include option.

Basic Examples (2)

Pick fractions from a data object:

Take an HPLC protocol as input:

Additional Examples (1)

Given list of chromatography datas:

Options (20)

App (1)

Set App -> True to launch interactive app:

Domain (2)

Domain can also be specified with time units:

Only consider fractions in the domain {26,28}:

Exclude (3)

Exclude the 10th fraction from the FractionsCollected list:

Exclude the fraction overlapping 28.5 Minute:

Get all TopPeaks, but exclude the fraction overlapping 26 minutes and the second fraction:

Include (3)

Include the fraction overlapping 22.5 Minute:

Include the second fraction and the fraction overlapping the 26 Minute mark:

Include the second fraction from the FractionsCollected list:

Options (2)

Explicitly specify TopPeaks option, and pull remaining options from previous fractions analysis:

Use options from previous fractions analysis:

Output (3)

Return only the picked fractions:

Return the entire packet:

Return the picked fractions and the reference:

OverlappingPeaks (2)

If no peaks are specified, then no selecting is done based on peaks. In this case no collected samples are returned:

Return only fractions overlapping the biggest peak:

TopPeaks (4)

By default, uses only the largest (by area) peak:

Use the 2 largest peaks:

Use TopPeaks->All to use peaks:

Use TopPeaks->None or TopPeaks->0 to use no peaks:

Messages (1)

InvalidPosition (1)

Positions to Include or Exclude cannot be greater than the number of collected fractions:

Possible Issues (1)

Include option overrides Exclude option because of the order in which the filtering occurs:
