14 Processing Data With an Allelic Ladder The second page of the Run Wizard includes parameters that govern how size and allele calls are made. The default settings are suitable for most analyses. Be sure that Only Call Alleles in CHM Panel and Auto Create CHM Panel are not selected.
15 Processing Data With an Allelic Ladder Select Auto Select Best Ladder and Auto Panel Adjustment. With these options selected, ChimerMarker will identify the best ladder sample for each sample file, and use it to create a better aligned Genotyping Panel.
16 Processing Data With an Allelic Ladder The data has now been initially processed. The data may look as though it s of poor quality, but this is because many peaks are flagged due to ploidy and heterozygous imbalance. At this stage, the alignment of the panel is most important.
17 Processing Data With an Allelic Ladder If the ladder sample is in bold, it means that the program was able to align the bins of the genotyping panel to the peaks of the ladder sample, creating a new shifted panel. Navigate to the Panel Editor (Tools -> Panel Editor) to save the newly created panel.
18 Processing Data With an Allelic Ladder Observe that that are now two Project Panels: the original genotyping panel, and a second panel, whose bins have been aligned to the allelic ladder sample.
19 Processing Data With an Allelic Ladder Save the newly created panel by clicking on it, and then navigating to File -> Save As New Panel. Give the new panel a name. After clicking OK, you should see the panel appear in the Panel Templates list. You may also export the panel by right clicking on it and selecting Export.
20 Processing Data With an Allelic Ladder Now, repeat the analysis using your shifted panel. Newly saved panels appear at the bottom of the panel dropdown list.
21 Processing Data With an Allelic Ladder For the second run, select Auto Create CHM Panel and Only Call Alleles Present in CHM Panel. With these options selected, ChimerMarker will create a project-specific Chimertyping Panel from your Genotyping Panel. Give a name to this new panel in the field above.
22 Processing Data With an Allelic Ladder Finally, in the last window of the Run Wizard, deselect Auto Select Best Ladder and Auto Panel Adjustment.
23 Processing Data With an Allelic Ladder Now a properly aligned Chimertyping Panel has been made and applied to the samples. The next section covers reviewing size and allele calls.
24 Reviewing Size and Allele Calls The next group of slides demonstrates the process of reviewing size and allele calls, in preparation for Chimerism Analysis. File Tree Electropherogram(s) Allele Report Table
25 Reviewing Size Calls Sizing quality is indicated by the icon to the left of each file name. Green indicates successful size calling. Red and Yellow icons indicate that a size call requires review. Click the Size Calibration Icon: to visualize size calls for each sample. Most size calling errors result from using the wrong size standard, or selecting the wrong standard color.
26 Reviewing Allele Calls During data processing, a Chimertyping panel is created and applied to your data. This panel includes bins for donor, recipient, and shared peaks only. Recipient The program labels each bin according to its origin: R for recipient, D for donor, and D1R for shared peaks. Mixture Donor
27 Reviewing Allele Calls Allele calls are summarized in the Report Table. Again, a color scheme is used to denote quality. Green icons indicate the peak passed all analysis parameters. Yellow icons indicate the peak is in the check range for at least one parameter, and red icons indicate the a peak failed at least one analysis parameter. The format of the report table can be modified extensively by clicking on the Report Settings Icon: The table can be exported as an excel or text file by clicking the Save icon:
28 Reviewing Allele Calls The Report Table is linked with the Electropherogram. Simply double click on an allele call to be taken to the corresponding peak trace.
29 Reviewing Allele Calls To obtain more information about an allele call, click on the Show Chart/Table Icon:
30 Reviewing Allele Calls To edit an allele call, simply right click on the corresponding peak bin and choose which action you d like to take. Notice that the Allele table is updated to show what action the user has taken.
31 Automated Chimerism Analysis After reviewing your Size and Allele Calls proceed to the Chimerism Analysis Application. Select your preferred Chimerism Type and Quantification Method. The default settings are recommended for the remaining parameters. Under the Additional Settings tab, you can set a limit of detection threshold, and choose to display stutter-adjusted Chimerism results.

Chimerism results will now be displayed for the new sample, and the sample cab be added to the Longitudinal Report as well.
43 Adding Samples to Project To add a sample to the longitudinal report, click the green check-mark icon: Only samples that haven t already been added to the report are displayed.
44 Double Donor Analysis The workflow of Double Donor Analysis is identical to that of Single Donor analysis. However, remember to identify all sample types (Donor1, Donor2, and Recipient) prior to data processing. And of course, when the time comes select Double-Donor Chimerism Analysis instead of single donor analysis.
45 Double Donor Analysis Donor 1 Donor 2 Colored flags are used to denote bins from Donor1, Donor2, the Recipient, or some combination of the three. Pre-Recipient In the Chimerism Analysis window, Donor1 and Donor2 chimerism results, and their corresponding errors, are calculated and displayed separately. Mixture
46 Troubleshooting After processing your data, you may find that some peaks or markers aren t being called. To investigate this further, navigate to the Panel Editor, which is under Tools -> Panel Editor
47 Troubleshooting The Panel Editor displays the alignment of your samples to various panel templates. The Project Panel is the panel that was used to process your data. Click on a panel to see it superimposed on your sample peaks.
48 Troubleshooting Because the Chimertyping panel is derived from the genotyping panel, misalignments in the Chimertyping panel are typically the result of misalignments in the Genotyping Panel. Chimertyping Panel Genotyping Panel
49 Troubleshooting You can manually align markers and allele bins in the panel editor by holding Shift, and Clicking on the marker name or allele bin. Continue to hold Shift and the Mouse key, and drag the mouse left or right. When you have shifted the marker or bin to your desired location, release the mouse key and the shift key. Save your changes, and then reprocess your samples with the newly shifted panel.
50 Troubleshooting Properly aligned bins in the genotyping panel produce well aligned bins in the Chimertyping Panel Chimertyping Panel Genotyping Panel
51 Troubleshooting In ChimerMarker 3.0.2, you can use the Fixed Bin Width feature as an alternative solution to this problem. This option widens the bins of the Chimertyping panel to the width input by the user.
52 Troubleshooting With this option selected, the program will widen the bins of a newly created Chimertyping panel. This will aid in calling slightly misaligned peaks that would have otherwise been missed. Main Analysis Screen Panel Editor
