Preprocessing

This category contains 6 nodes.

Baseline Subtraction 

Use this node to perform baseline subtraction to remove baseline noise from the spectra.

Image ROI 

We use this to limit incoming MSI imzML data into a rectangular Region of Interest.

Limit m/z Range 

Use this node to limit the m/z values in a range between a user specified minimum and maximum.

Normalizer 

We use this node to Normalize rows of data in several different ways specified by the user. This node is targeted towards the processing of mass […]

Rebinner 

We use this node to rebin the data, this should be one of the first steps in preprocessing the mass spectrometry data. This is aimed to convert […]

Smoother 

We use this to denoise inherently noisy MSI datasets, from a choice of 3 different smoothing methods.
