Issues Resolved
Issues that are fixed in v3.9.5
| Defect ID | Component | Description |
|---|---|---|
| DRAGEN- 14274 | Cloud Infrastructure | Fix for crash with “HW License V2 |
expected” on new cloud instance (AWS and Azure) due to a register access
attempt before fpga image is loaded.
DRAGEN- 14152| All| Fix several security vulnerabilities.
DRAGEN- 14188| SNV VC| Fix hang in MNV detection when GVCF mode is enabled.
DRAGEN- 14258| Cloud Infrastructure| Fix self_test.sh for AWS instances, allow
the license url argument
DRAGEN- 14167| SNV VC, Mito| Fix for missing homref scores in Germline Mito
GVCF. Somatic homref scores are changed to an evidence measurement rather than
a posterior probability, in line with the GQ scores reported for germline
homref. This allows zero-depth positions to get a score of zero.
DRAGEN- 14380| BCL| Fix a BCL conversion crash when config.xml is present in
BaseCalls on aggregated bcl input (HiSeq/MiSeq).
DRAGEN- 14297| Somatic CNV| Fix a CNV hang in somatic mode

when running Joint Genotyper from Gvcf Genotyper input
DRAGEN- 13837| Gvcf Genotyper| Fix for Hail crash on ChrM with Gvcf Genotyper
output, by correcting header SQ entry
DRAGEN- 14799| Trimmer| Make read-trimming option validation stricter, to
resolve potential failure mode
DRAGEN- 14798| Trimmer| Add validation check for ‘cut-end’ trimmer and related
trimming options, to resolve potential failure mode
Known Issues
Known issues of the DRAGEN™ v3.9.5 release
Defect ID| Component| Issue Type| Description| Remedy /
Workaround
---|---|---|---|---
DRAGEN- 14966| CRAM, Alt-
masking
| Bug| CRAM generated with alt-masking HT may not be decodable by 3rd party| Reads which map to regions that are masked may be affected. The workaround is to apply masking to the fasta and use that fasta to decompress the CRAM. The issue is present since alt-masking was introduced in 3.9.3
and will be fixed in DRAGEN v3.10
DRAGEN- 14902| Infrastructure| Usability| DRAGEN hangs on corrupted (truncated) BAM input| Some types of BAM truncation may lead to hang in DRAGEN. User will be
able to quit the hanging job via CRLT+C and fix their input and re-run.
DRAGEN- 14890| SNV VC| Bug| Segmentation fault in MNV| When using the distance bed option to specify combination distances, some bed files lead to a crash in MNV processing. The issue exists in 3.9.3
release. The workaround is to use
| | | | command line option instead of BED file.
DRAGEN- 14794| Metrics| Bug| QC region coverage metrics reports more aligned
reads than WGS coverage metrics| Use the aligned reads from the WGS coverage
metrics
DRAGEN- 14755| RNA| Usability| RNA gene fusion output md5sum difference
between U200 Phase2 and Phase4 servers due to precision| VCF may not be bit
exact match, due to insignificant floating-point differences. The score is
used to filter false fusion candidates. Candidates with a score < 0.5 are
marked as failing whereas candidates with a score
0.5 are marked as passing if they also pass other criteria. Based on this, only candidates which have a score close to 0.5 may be affected by this issue, but the issue is seen only on
very low score values
DRAGEN- 14743| CNV| Usability| Sample excluded from sex genotyper metrics file| A user may include N samples to be used in the panel of normals, for CNV normalization. As part of the algorithm, a sample may be removed from the set if it does not meet certain quality requirements (such as having too many 0 coverage regions). When this happens, the remaining n < N set of samples is used. The remaining n samples will have their Sex Genotype reported in the output cnv_metrics.csv. Known behavior, not a bug. Some users may still be interested in the estimated gender of samples that have been removed, so this will be changed
in DRAGEN v3.10
DRAGEN- 14727| Metrics, Graph Genome| Bug| DRAGEN graph genome
– discrepancy in coverage stats results
| A coverage metric for graph genome is incorrect. This issue is present in
3.9.3 also. No workaround
DRAGEN- 14526| Methylation| Bug| Multi-pass methylation does not report number
of duplicates in mapping metrics.| Duplicates are not reported in metrics for
multi-pass methylation. No workaround.
The metric is calculated now in the new “single-pass” methylation flow, which is the recommended way to run
methylation.
DRAGEN- 14513| FPGA| Usability| Deflate engine error: 0x9080 on stream 1 on
EAGLE server| Very rare intermittent hardware issue on Phase1 server FPGA
leads to crash. Rerun of the sample will succeed.
DRAGEN- 14511| Cloud Infrastructure| Usability| [AZURE] Error in
`/opt/edico/bin/dragen’: corrupted size vs. prev_size: 0x00002b10140015ef|
This crash was encountered once on Azure and has not been reproducible. A re-
run will succeed
DRAGEN- 14390| CRAM| Usability| DRAGEN hits segmentation fault on| When
incorrect reference is used to process CRAM input, the system may crash. This
has been the behavior of
| | | CRAM input mismatched with reference| DRAGEN with CRAM input. Select
correct reference and re-run.
DRAGEN- 14373| Infrastructure| Usability| Trailing whitespace on the dragen
command line cause an error| Trailing whitespace can lead to command line
parsing error, and dragen exits.
DRAGEN- 13977| Infrastructure| Usability| dragen_drv does not compile on linux
kernel 5.8.0| dragen driver does not compile on Ubuntu with on linux kernel
5.8.0
DRAGEN- 13896| CNV| Bug| Panel of Normals filtering applied incorrectly|
Affects CNV panel-of-normals feature, which is still officially supported but
no longer recommended. Will not be fixed.
The feature shall be deprecated.
DRAGEN- 13887| Methylation| Bug| Methylation reporting only assertion failing
during processing| Encountered when using methylation report compression. The
workaround is to disable report compression
DRAGEN- 13818| HT Builder| Usability| Custom reference failing at alignment
due to compression issue| Some small custom references cannot be built by the
hash table builder.
There is no workaround.
SW Installation Procedure
-
Download the desired installer from the Illumina support website and unzip the package
-
The archive integrity can be checked using: ./ –check
-
Install the appropriate release based on your Linux OS with the command: sudo sh
-
