CNVineta: a data mining tool for large case-control copy number variation data sets.
Background
CNVineta is a flexible data mining tool for the analysis of copy number variations (CNVs) in large case-control SNP array data sets. The tool is available as an R statistical package. CNVineta offers a flexible and fast access to CNVs by a quick graphical overview in large case-control datasets. In addition, CNVineta provides rapid access to the log2 of raw data ratios (LRR) and B-allele frequencies (BAF) of specific or all samples, thereby allowing for a fast verification of the underlying raw data. CNVineta is also equipped with analysis methods for genome-wide screening for associated rare as well as common CNVs. Hence, CNVineta is a unique data mining tool to rapidly explore CNVs in large case-control data sets.

Change Log
CNVineta_1.0-1
- stats of visualizeRegion: counts CNVs and calculates p-values for the segments which overlap the requested area only. Not for the entire picture/plot
- visualizeRegion(): additional graphical parameters. plot.pch for point type. plot.dot.cex for point size. fixed.LRR.scale= FALSE/TRUE for the same y-axis scale for all LRR plots of the same region
CNVineta_1.0
- dox0(): visualizes all CNVs within the visualized region and does not skip CNVs any more which do not overlap the area/"atom" of interest.
- dox0(): can run multiple rules in one step. E.g. min.diff=c(3,5) and max.one.side=c(0,1) allowing for the 3/0 and 5/1 screening in a single run
CNVineta_0.9-9
- dox0(): running chromosome wise now => less memory required
- a few changes regarding exception handling of different functions
CNVineta_0.9-8
- removeChromosomeData(): "empty query" bug fixed, LRR plot for Illumina data bug fix (rs prefix for Illumina SNP marker)
CNVineta_0.9-7
- QQ plots, Manhattan plots, Bonferroni's correction for multiple testing, CNV load and LRR based glm implemented.
- minor changes regarding exception handling on missing or wrong input
- major changes in the user guide (v1.8 to v1.9)
CNVineta_0.9-6
- Help page for do.log.regression more detailed
- "get Raw data failed" error message now explains for which subset it failed, when called from getHeatmap
- minor changes in the user guide (v1.7 to v1.8)
