rCGH 1.9.4
Minor changes
- Error on "Affy_snp6_cnchp.txt.bz2" demo file, fixed.
rCGH 1.9.1
Minor changes
- Vignette formating in order to meet the guidelines of the
"Bioconductor LaTeX Style 2.0".
rCGH 1.3.4
Major changes
- EMnormalize() has a new 'priorScale' argument (default to 5) to optimize
the gaussian mixture analysis and the identification of the major L2Ratio
peaks.
NEW FEATURES
- The rCGH package now supports Affymetrix OncoScan arrays. As for SNP6.0
and CytoScan arrays, CEL files must be processed by the user first, using
either ChAS or Affymetrix Power Tools. See ?readAffyOncoScan for more
details.
rCGH 1.1.8
- The centralization is now estimated on the distribution of segment values,
so after the segmentation step. This mean that now users have to run
segmentCGH() before EMnormalize().
- plotProfile() gains a 'showCopy' argument. When set to 'TRUE', the
profile's y-axis will use the estimated copy numbers instead of the
Log2Ratios.
- The read() functions, used as rCGH-Object constructors, take a
supplementary 'ploidy' argument. When known, this value can be used in order
to estimate gains and losses expressed in copy numbers. Default to 2.
- Copy number estimation is also reported in all of the tables, inlcuding
the main by-probe table accesible through getCNset().
rCGH 1.1.7
NEW FEATURES
- The user can now specify what supplementary genes annotations to export
through the byGeneTable() function. Allowed annotations are those supported
by the 'select' method from the 'AnnotationDbi' bioconductor.
rCGH 1.1.6
BUG FIXES
- Errors occured when mergin short segments, with respect to the minLen
argument in segmentCGH().
rCGH 1.1.5
Cleaner version from 1.1.4
Should not give any warning due to functions masked by imported packages
rCGH 1.1.4
NEW FEATURES
- Read Illumina HumanOmniExpress: this function has been temporarily
removed. Illumina data require to much memory for annotating probes when
probe locations are missing in the data.
rCGH 1.1.3
NEW FEATURES
- Read Illumina HumanOmniExpress: see readIllumina() help in the rCGH
documentation.
- New rCGH-generic class for custom arrays: see readGeneric() help in the
rCGH documentation.
- Supports arrays designed according to hg18, hg19 (default) and hg38. To be
specified by the user in the read functions and in the byGeneTable function.
- plotProfile now as pCol and GLcol arguments, for points and gained/lost
segments, respectively.
rCGH 1.1.2
BUG FIXES
- Major bug fixed in the view() function: one function was not properly
called.
rCGH 1.1.1
Not submitted
rCGH 1.1.0
New bioconductor devel versioning after release cycle
The first and corresponding bioconductor release version is 1.0.0
rCGH 0.99.10
BUG FIXES
- In view() function: segment colors were not properly assigned.
rCGH 0.99.9
BUG FIXES
- In view() function: segment colors were not properly assigned.
rCGH 0.99.8
BUG FIXES
- Error when merging probes with duplicated locations on
Agilent CytoGenomics 3.0: fixed.
rCGH 0.99.7
SIGNIFICANT USER-VISIBLE CHANGES
- byGeneTable() is not a S4 method anymore but S3: as argument, it takes a
segmentation table exported from a rCGH object, and not the object itself.
As a consequence, byGeneTable() can be used on any segmentation table of the
same form as those exported from a rCGH object.
- The full by-gene table is not stored in rCGH object, but built then
exported on the fly, using byGeneTable().
- Supplementary argument in getSegTable(): minLen allows the user to
specify the minimal segment length, in Kb. Segments shorter than this value
are merged before the segmentation table is exported. The original table is
still stored in the rCGH object.
- New features in plotProfile() and multiplot(): one or multiple genes can
be tagged. As for getSegTable(), the minimal segment length (in Kb) can be
specified.
- Server version for the interactive viewer is described in the vignette.
BUG FIXES
- byGeneTable:
. In the exported by-gene table, the corresponding segment lengths were
not properly reported.
. Errors occured when a gene was covered by 2 segments.
