Genomic region
You can provide custom annotation information for specific regions of interest in the genome when you import a genomic region annotation source file.
-
The genomic region annotation source file must be a .txt format file with four, tab-separated columns. Columns must list a chromosome number, start value, end value, and annotation values.
-
Enter custom annotations in the Annotation value column of the file, as key-value pairs separated by semi-colons.
The information in your input genomic region annotation source file is used in the following ways in your analysis results:
-
In the Analysis Results screen
In the downloaded TSF variant files, information from the Annotation values column is added to matching variants in your analysis results.
-
In the Analysis Results screen, you can create a filter based on the first key-value pair in the . (Only the first key-value pair can be used as a filter.)
Here is an example file:
#CHROM Start End Annotation values chr1 000000 000001 fld1=abc;fld2=123;fld3=this chr1 000001 000002 fld1=abd;fld2=124;fld3=that chr1 000002 000003 fld1=abe;fld2=125;fld3=this chr1 000003 000004 fld1=abf;fld2=126;fld3=that chr1 000004 000005 fld1=abg;fld2=127;fld3=this chr1 000005 000006 fld1=abh;fld2=128;fld3=that
The hit level for a genomic region annotation source is not configurable and is always set to overlap.
