Written by Aubray Prévot

Note: If you have any question or if your format is rejected, fell free to contact our team to the email address at oncokdmsales@oncodna.com.

  1. BASIC REQUIREMENTS

a. Input definition
VCF file must be compatible with VCF version 4.0 (or higher) specification: vcf4.0
​
​b. Reference genome
Application only support hg19/GRCh37 reference genome, if your input file was produced against hg38/GRCh38, you can use following online tool to convert genomic coordinate:
​
• NCBI remap: https://www.ncbi.nlm.nih.gov/genome/tools/remap
Additionally to this, reported alteration on mitochondrial chromosome and patch sequenced will be filtered out as they will not lead to usable data for biological analysis.
​
​c. Sample content
Input file must contain one and only one sample, if none or multiple samples are found in file, it would be rejected.
​
​d. Alteration content
OncoKDM application support VCF only for small nucleotide alteration (i.e. SNV/MNV an short InsDel). All structural variations describe in input file will be filtered out.
