FILTER
|
If all filters are passed, PASS is written in the filter column.
|
•
|
artifact_in_normal–TLOD of the normal read set (Normal artifact LOD) exceeds threshold. |
|
•
|
base_quality–Site filtered because median base quality of alt reads at this locus does not meet threshold. |
|
•
|
clustered_events–Clustered events observed in the tumor. |
|
•
|
DRAGENHardQUAL–Applied to sites with QUAL < 10.41 (default cutoff) |
|
•
|
fragment_length–Site filtered because absolute difference between the median fragment length of alt reads and median fragment length of ref reads at this locus exceeds threshold. |
|
•
|
germline_risk–Evidence indicates this site is germline, not somatic. |
|
•
|
lod_fstar–Applied to sites in the mitochondrial contig where lod < 6.3 (default cutoff) |
|
•
|

|
•
|

|
•
|
mapping_quality–Site filtered because median mapping quality of alt reads at this locus does not meet threshold. |
|
•

|
•
|
PloidyConflict–Applied to sites where the genotype call from the variant caller is not consistent with chromosome ploidy (eg, chrY in Female subjects). |
|
•
|
read_position–Site filtered because median of distances between start/end of read and this locus exceeds threshold. |
|
•
|
str_contraction–Site filtered due to suspected PCR error where the alt allele is one repeat unit less than the reference. |
|
•
|
t_lod–Tumor does not meet likelihood threshold. |
|

FORMAT
|
The format column lists fields separated by colons. For example, GT:GQ. The list of fields provided depends on the variant caller used. Available fields include:
|
•
|
AD—Allele Depth (counting only informative reads out of the total reads) for the ref and alt alleles in the order listed; if the GT is 0/0, the AD is the reference count. If the GT is 0/1 or 1/1, the AD is of the form X,Y, where X is the reference allele count and Y is the alternative allele count. If the GT is 1/2, the AD is of the form Y,Z, where Y and Z are the alternative allele 1 and 2 counts. |
|
•
|
AF–Allele fractions for alt alleles in the order listed. |
|
•
|
DP–Approximate read depth (reads with MQ=255 or with bad mates are filtered). |
|
•
|
F1R2–Count of reads in F1R2 pair orientation supporting each allele. |
|
•
|
F2R1–Count of reads in F2R1 pair orientation supporting each allele. |
