We are currently receiving a large number of applications for data submission, and the review process is taking longer than usual.We sincerely apologize for the delay and kindly ask for your understanding. When submitting an application, we would greatly appreciate it if you could allow sufficient time for the processing.

Following a change to our organizational structure effective April 1, 2026, this division has been renamed from the "Database Center for Life Science, Joint Support-Center for Data Science Research" to the "Database Division for Life Science (DBCLS), BioData Science Initiative (BSI), National Institute of Genetics (NIG)". Where the former name still appears in the guidelines, please read it as the new name.

Realignment and base quality recalibration
GATK 3.7
Mapping quality
Reads with MAPQ<20 were excluded at variant calling with GATK 3.7 HaplotypeCaller
QC and filtering
Data with bad base quality and high %GC content were removed.
Alignment:
Data matched for the following conditions were removed.
- Low mapping rate
- Different insert size
- Gender information mismatch between meta-data and genotype data
- Suspected sex chromosome aberration
Genotyping:
GATK's best practices include a variant filtering step following Variant Quality Score Recalibration (VQSR)
- DP/GP (DP < 5, GQ < 20, DP > 60, GQ < 95)
- Heterozygosity (F>=0.05)
- Hardy-Weinberg equilibrium (p < 10^-6)
- Repeat & Low Complexity
Principal Component Analysis (PCA):
PCA was performed with individuals included in the 1000 genomes project and outliers from Japanese cluster were removed.

After these filtering steps, variants located in the regions listed as the HighConfidenceRegion (Genome-In-A-Bottle project) were flagged.
