Mass spectrometry data are available via ProteomeXchange with identifier PXD009301 NGS datasets are available at the European Nucleotide Archive (ENA) under accession number PRJEB25673. NGS and MS data were handled and annotated using the B-Fabric Türker et al. (2010) information management system and are available for registered users under the project identifiers 1644 and 1875. The following content is descibed in more detail in Egloff et al. (2018) (under review NMETH-A35040).
make-data.R
)The package contains only a subset of the most important data generated over a period of five years. To get an impression an overview of all annotated sample (S) and workunits (W) in the B-Fabric system, Türker et al. (2010), is graphed in the timeline plots.

make-data.R
)NL42_100K.fastq.gz
Sample NGS data contains 100K merged MiSeq reads that demonstrate the linkage between nanobodies (NB) and flycodes (FC) in FASTQ.
NL42_100K <- NestLink:::.getReadsFromFastq("inst/extdata/NL42_100K.fastq.gz")
save(NL42_100K, file="inst/extdata/NestLink_NL42_100K.RData")
knownNB.txt
An optional part of the NestLink workflow is the usage of known nanobodies in the sequencing experiment to estimate sensitity and specificity levels. This example file contains nucleotide sequences of nanobodies that should be detectable in this experiment. In the later workflow, these nanabodies are highlighted and labeled as known NB.
nanobodyFlycodeLinkage.RData

to the two previous files.

NB.tryptic
and FC.tryptic
Both files are the output of the previous NGS step generating the linkage between NBs and FCs.
The files are used to demonstrate the detectability of the AA sequences.
The wrapper functions are extended by the SSRC prediction and the parent ion mass (pim) determined by using protViz.
The column ESP_Prediction
was generated by using the service from https://genepattern.broadinstitute.org, see also Fusaro et al. (2009).
