Methods
Analysis workflows in Ion Reporter™ Software
To analyze your Oncomine™ Focus Assay data using Ion Reporter™ Software:
• In Torrent Suite™ Software, if your Planned Runs were set up correctly,
automated analysis has already been performed and you can view the
Oncomine™ analysis results in Ion Reporter™ Software.
• In Torrent Suite™ Assay Development Software, you can import the run data into
your local Ion Reporter™ server for further analysis.[1] For detailed instructions,
see the latest Ion Reporter™ Software User Guide, available on the Ion Community at
the following link: ioncommunity.thermosher.com/docs/DOC-9594.
Note: For instructions on manually launching an analysis, see “Launch an
Oncomine™ Analysis in Ion Reporter™ Software“ on page 9.
Note: Microsoft™ Excel™ is required for viewing VCF, CSV and TSV les.
Available workows in Ion Reporter™ Software include:

4. Here, you can sort results in many ways, including:
• Sort the analyses chronologically in the Created On column.
• View details of an analysis, click on the blank space in the analysis’ row.
• Click on the sample’s hyperlink (in the Analysis column) to open its variant
review grid.
5. You can also use a variety of approaches for sorting and ltering data. Use of the
Oncomine™-specic annotations are described here. See software's help menu for
more options.
a. Click on the hyperlink in the Analysis column to view the Analysis Results
variant review grid.
b. In the Filter Chains panel on the right, notice that the Oncomine Variants,
5% CI CNV ploidy >= gain of 2 over normal (5.0) lter chain has been
applied by default. This lter chain removes variants that do not match this
lter. For more information on this Filter Chain option, please see Appendix:

6. On the Oncomine tab, you can sort variants in the Oncomine Variant Class and
Oncomine Gene Class columns.
7. Click on the Ontologies tab. Here you can sort variants by Type or by Genes.
Export Results
Once you have determined your variants of interest, you can export a report.
1. Click the Download buon. Choose All Variants, Filtered Variants or Current
Results TSV. (For this example, we chose Filtered Variants.)
The software generates a zipped le with four folders: QC, Variants,
Workow_Seings, and CNVBaseline. Within the Variants folder, you’ll nd the
Oncomine™ annotated VCF le, which is used by the Oncomine™
Knowledgebase Reporter. For more information on the CNV output les, see the

11. Click Launch Analysis buon. This step may take up to 10 minutes. The
software is adding Oncomine™ annotations to variants which have already been
algorithmically detected by the variant caller algorithm and are present in the
VCF le. For the other three workows, variant caller, mapping, and annotation
algorithms are applied to the sample, followed by the adding of Oncomine™
annotations to the VCF.
12. From the Analysis Results page, you can lter your results. On the right side of
the screen, you’ll nd Filter Options. (In this example, we found 3 variants.)
13. In the Filter Chains panel, notice that Oncomine Variants, 5% CI CNV ploidy >=
gain of 2 over normal (5.0) has been applied by default. This lter chain changes
the table so that only the Oncomine™variants are shown.
14. At this point in time, you can download a results zip bundle which includes an
annotated VCF le and other analysis results les.
15. From the Download buon, you can choose All Variants or Filtered Variants. (For
our example, we chose Filtered Variants.)

CNV Baseline Creation
In AmpliSeq™ assays, Copy Number estimates are made by counting reads for each
amplicon, making adjustments to account for certain types of variability, comparing
those read counts to expected counts for those amplicons in a "normal" sample, and
then making further adjustment.
Known sources of variability include pool imbalance (when the assay has more than
one pool of amplicons), total number of reads and per amplicon aributes of GC
proportion, and length of the amplicon insert. In practice, we observe other variability
that does not associate with known aributes yet is systematic. The method we use
trains on a large number of diverse samples, captures systematic eects, and encodes
these into a le (the "baseline").
When augmenting a baseline, new samples are run, the size of each systematic eect
encoded in the baseline is estimated, and a correction is applied to remove the eect.
These added samples need not be normal, and should be diverse so as to capture
likely systematic variation.
The following instructions walk you through using the new Variability Correction
Information Baseline (VCIB) CNV baseline, creating a new VCIB CNV baseline, or
augmenting an existing VCIB CNV baseline for Oncomine™ Focus Assay panels.
Use new VCIB CNV Baseline
If you want to use the new VCIB CNV baseline included in Ion Reporter™ Software
v5.0, simply select it when creating your workow. See Create an Ion Reporter™ CNV
Workow section for details.
Create a CNV Baseline
Ion Reporter™ Software provides a wizard to guide you through Copy Number
Variation (CNV) Baseline creation.
1. Click the Workows tab, then click the Presets sub-tab.

2. On the Create Preset menu, select Copy Number Baseline.
3. Select AmpliSeq.
4. Select Oncomine Focus Panel v1.1 Regions as your Targets Region le. Click
Next.

5. On the Algorithm Type page, select CNV VCIB 1.0 for the latest CNV algorithm
to be applied. Click Next.
6. Select at least 48 samples and ag at least 6 of these "Normal" and click Next.
Male or Female gender must be specied for Normal samples, but samples not
agged as normal can be male, female or unknown. You can use the Summary
panel to see your totals.
7. Enter a name for your baseline and then click Create Baseline to save it.
Note: Logs for both successful and failed analyses include the
"BaselineCreation.log" le which has the BAM les named that were rejected due
to similarity to other les in the baseline, as well as the
"map.TmapMergeActor-00.err" le which has the BAM les named which were
rejected due to QC failure.
Next, proceed to the Create an Ion Reporter CNV Workow section where you will
add this new baseline to your workow.
