Creates the DGV table in the database of known cnvs.
This executes the SQL CREATE query corresponding to the DGV (Database of Genomic Variants) schema. It does so by reading a compressed text file named ‘dgv-variants-hg19.txt.gz’ representing a database dump in a text file.
Queries the dgv table for known overlapping CNVs.
| Parameters: | cnv (cnv_struct.cnv) – The cnv object to query for overlap. |
|---|---|
| Returns: | A list of overlapping CNV objects. |
| Return type: | list |
Internally, this generate the corresponding SQL SELECT from the cnv object and queries the sqlite database.
Note
The elegant method for detecting overlaps is from Stack Overflow.
