You can see and retrieve various information about your sample(s) and the results of the analysis. This article lists the available options.
You can access the "Variant List" options in two ways: i) From the Dashboard, by clicking in the upper right corner of the analysis, and ii) in the "Analysis Actions" menu of the upper right corner at the variant table page. You can choose among a series of actions that allow you to retrieve information or generate different reports, providing an overview of your results, or further explore the analysis.
- SNVs & Indels: The results of the analysis. When clicked at the Dashboard leads to the variant table.
- Phenotype -Disease information (Sample): Using these fields it is possible to add and modify the clinical description of the sample. You can choose this option if you want to provide phenotypes and diseases associated with your case from a drop-down menu or view the already selected ones. The phenotypes/diseases will be matched to the resulting variants. The phenotypes/diseases will be matched to the resulting variants, as described in the article Phenotype Matching.
- Sample/Analysis information: Opens a pop-up table with an overview of information about the sample, the sequencing (e.g. the capture method, number of reads and bases in reads, sequencer), and the analysis (e.g. the versions of the databases and the implemented pipelines and software).
- Reuse sample files: This option is available if you wish to reuse an existing sample for a new analysis. A blue box message in the upper right corner of the page will let you know that you will receive an email when the input file(s) of the sample is/are again available for new analysis and which you can view in the "Upload / view files" page.
- Gene coverage: When clicking on Gene Coverage, a new window will open showing a tree with the coverage per gene. Please note that only information for 100 or fewer genes is shown since the depiction of more genes would be impractical. If you wish to see coverage information for analyses with more than 100 genes, please use a gene list to limit the displayed results to 100 genes or fewer. If this option has been selected when analyzing a gene list, the tree will contain only the genes from that gene list. Clicking on any gene will result in a tree of its transcripts and each transcript is also expanded to a tree showing the coverage of individual exons. Clicking on an exon will open a new tab, showing the read coverage from the corresponding bam file.
The following options concern the generation of different reports and can be useful when the user needs to check the quality of the sequencing in terms of coverage or retrieve information about the alignment. Refer to the article Report files to download for more information.
- View QC report - Download QC report (PDF) - Download QC report (docx): You can view/download in Word or PDF format, a quality control report about your analysis. The report includes a list of information such as sequence technology, read alignment results, regions reported, coverage, number of identified variants by class, summary for ACMG rules, and number of SNV found in coding regions.
- View FastQC report: A quality control report for high throughput sequence data. For more information please see the documentation of the fastqc tool at http://www.bioinformatics.babraham.ac.uk/projects/fastqc/.
- Download VCF: A compressed (*.vcf.gz) vcf file will be downloaded with the results of the variant calling.
- Download BAM file: Download the bam file (the sample’s reads aligned against the reference genome) used in the analysis.
- Download BAI file: The BAI file format is the index file of a BAM file. This is a companion file for your previous BAM file, which doesn't contain any sequence data but acts as an external table of contents allowing a computational tool to navigate in the BAM file and locate specific parts.
- Coding coverage report: You can use a previously created gene list to produce an Excel document file reporting coverage information of the coding regions included in the analyzed gene list.
- Region list coverage report: You can use a list of regions of interest to produce an Excel document reporting coverage information. Contact us in case you want to add regions to your analysis.
- Downloads: This option directs you to a new screen where you can see any files associated with this analysis that are ready to be downloaded.
- Coverage report for targeted regions: Generates a coverage report for the regions captured by the specific assay that you selected when launching the analysis.
- New Gene-List Analysis: This option will re-start the analysis with the same sample using a previously generated gene list of selected genes or a gene list created from selected phenotype(s) or disease(s). It will appear as a sub-analysis of the initial analysis.
- New Algorithmic Filter Analysis: Opens a new screen with the available algorithmic filters, as seen in section 3.2. Please click on the info icon, to get a description of each filter. Algorithmic filters create a snapshot of the parent analysis, with a filtered subset of variants, according to each Algorithmic filter. You can run a sub-analysis choosing a filter from the list or you can ask for a custom made filter. Please see Algorithmic FIlters.
