The format of "halo.lowres" is: chr [1:3] "data.halo.lowres" "kernel.halo.lowres" "gene.coords" The format of "halo.hires" is: chr [1:3] "data.halo.hires" "kernel.halo.hires" "gene.coords" The format of "yeast.gcn4" is: chr [1:4] "data.yeast.gcn4" "kernel.yeast.gcn4" "kernel.yeast.gcn4.jbd" "gene.coords"
"halo.lowres" loads:
"data.halo.lowres" – low-resolution HaloSpan Halobacterium sp. TfbD
ChIP-chip data, formatted for input to chip.deconv() and
deconv.entire.genome(). Data is described in ref. (1) below.
"kernel.halo.lowres" – deconvolution kernel learned for this data
via fit.peak.profile().
"gene.coords" – map of gene coordinates for this organism for use
in plotting functions.
"halo.hires" loads:
"data.halo.hires" – high-resolution Nimblegen format Halobacterium sp. TfbD
ChIP-chip data, formatted for input to chip.deconv() and
deconv.entire.genome(). Data is described in ref. (1) below.
"kernel.halo.hires" – deconvolution kernel for this data via fit.peak.profile().
"gene.coords" – map of gene coordinates for this organism for use
in plotting functions.
"yeast.gcn4" loads:
"data.yeast.gcn4" – 266bp-resolution S. cerevisiae Gcn4
ChIP-chip data, formatted for input to chip.deconv() and
deconv.entire.genome(). Data is described in ref. (1) below.
"kernel.yeast.gcn4" – deconvolution kernel for this data via fit.peak.profile().
"kernel.yeast.gcn4.jbd" – deconvolution kernel used by ref. (2) for
the JBD algorithm.
"gene.coords" – map of gene coordinates for this organism for use
in plotting functions.
