CGH Data Dumper
The CGH Data Dumper plug-in exports typical BAC data in several different simple formats readily accessible for e.g. Excel, CGHExplorer, and MeV CGH viewer. The plug-in works on a normal BASEfile (matrix mode). Therefore, before running this plug-in, you might want to join array designs using the VirtualArray plug-in.
This plug-in is currently unsupported at supplied as is. The plug-in is written by Johan Staaf at the Dept. of Oncology at Lund University.
Exported fields are
ReporterId = BAC clone Id
GeneSymbol = Gene symbols of genes mapped to the BAC clone. Could be bundled using:
Chromosome
Cytoband
StartPosition = Start position in BP for the BAC clone
EndPosition = End position in BP for the BAC clone
M = Log2(ratio)
Note that the CGH formats do require probes to be exported to have a genomic mapping.
Formats
Standard Format
Format of header line is the above common columns and then the assays with assay names in the header.
Lite Format
Format of header line is reporterId, chromosome, start, stop, and then the assays with assay names in the header. NOTE: This format is compatible with MeV CGH viewer.
Sample Name export
Only the sample names are exported into a file. No spot data.
Sample Name and annotation export
The sample name and a chosen annotation is exported into a file. No spot data.
Annotation statistics
By specifying in the appropiate text field below in the format
e.g. |ER status|brca_family_status|..| you can get a summary of how
many assays has a certain annotation value for each of the specified
annotation types.
BED format
This creates a format similar to BED format as defined by UCSC and Ensembl. Contains four columns; chr, start, stop, amd reporterId. You can use BED files to create your own tracks in the UCSC genome browser.
Single file Lite
This creates one file for each assays. The file name speciefed as a parameter will be the suffix to the assay name. E.g specifying myfile.txt will create a file for Ca13928 as Ca13928_myfile.txt .The format of the individual files are the Lite format (see above).
Complete annotations to file
The annotations for all assays are printed to a file. Blanks are filled with NA
Selected annotations to file
Only selected annotations and their assays are printed to file. Blanks are filled with NA.
Mev + annotations
An MeV compatible file is printed containing annotations. This format is experimental and needs to be completed.
Annotation Display dump for selected annotations
For annotation display option. Enter selected annotations in the
format:
|ER Status|p_brca_family_status|etc..|
These annotations will be separated and a matrix created with N rows =
N samples and for each annotation value type, a column will be made
with N rows, where each row entry is 1 (annotation value exists for
this assay) or 0, no annotation value.
Parameters
- [Optional] Give a valid full file name for the created file.
- [Optional] Sort the data as well. NOTE! Using the sort option may require you to increase the RAM usage considerably if working with large data sets.
- Select export mode. Either standard or standard_lite as described above, or format suitable for Agilent CGH-analytics software.
- Select annotation for sample name and annotation export
- Define annotation types for annotation statistics in the form
|ERstatus|brca_family_status|...|
Download and installation
There is currently no detailed notes on how to install the plug-in in BASE 1, please fall back on the BASE 1 documentation on how to install plug-ins. Download the files from the repository
BASE 2
In BASE 2 this plug-in can be run using the Base1PluginExecuter. Simply create a configuration for the CGH Data Dumper following these steps:
