This is the data used in Nikolovksi et al. (2012). See below for
details and references.
Usage
data(nikolovski2012)
data(nikolovski2012imp)
Format
The data is an instance of class MSnSet from package MSnbase.
Details
These data are a concatenation of 4 LOPIT experiments. Experiments 1
and 2 are from Dunkley et al. 2006 (see also dunkley2006).
Exepriments 3 and 4 are new.
In the LOPIT experiments by Dunkley et al. (2006), peripheral membrane
proteins were removed by carbonate washing of the isolated membranes,
while for experiments 3 and 4, no carbonate wash was performed and
are, as such, enriched in peripheral and luminal proteins.
See figure 1 in Nikolovski 2012 for a description of the design.
In nikolovksi2012imp missing values have been imputed using
partial least-squares regression.
The training set used for the Naive Bayesian classifier is available
as the markers feature meta-data. Note that Nikolovksi included
a group of markers labelled 'others', which has been retained in these
data sets. The results produced in this work are available in the
preds feature variable (note that some organelles are
marked with a '*', which is undefined here).
