Artifact Type
Indicates that the variant at is not naturally present in the sample, but instead, it is formed by artificial means, such as during preparation of the sample; for example, a Sequencing artifact. A single default value, None, is supplied for artifact type. Additional values can be specified through the Add/Edit Object function in Geneticist Assistant.
Average Coverage

A minimum value for the status of a region to be classified as “Passed” can be set on the Quality Control tab of the Settings dialog box.
B
BED file
A BED file is a tab-delimited text file. A panel can be created from a BED file for use in Geneticist Assistant. Each row in the file contains a region of the reference that is to be used in Geneticist Assistant. At a minimum, the file contains the following information:
Field #1 - Chromosome number for the region
Field #2 - Chromosome start position
Field #3 - Chromosome end position
Field #4 - Optional comment column
