# QA/QC

Partek Flow contains a number of quality control tools and reports that can be used to evaluate the current status of your analysis and decide downstream steps. Quality control tools are organized under the Quality Assurance / Quality Control (QA/QC) section of the context-sensitive menu and are available for unaligned and aligned reads data nodes.

This section will illustrate:

* [Pre-alignment QA/QC](/partek-flow/user-manual/task-menu/qa-qc/pre-alignment-qa-qc.md)
* [ERCC Assessment](/partek-flow/user-manual/task-menu/qa-qc/ercc-assessment.md)
* [Post-alignment QA/QC](/partek-flow/user-manual/task-menu/qa-qc/post-alignment-qa-qc.md)
* [Coverage Report](/partek-flow/user-manual/task-menu/qa-qc/coverage-report.md)
* [Validate Variants](/partek-flow/user-manual/task-menu/qa-qc/validate-variants.md)
* [Feature distribution](/partek-flow/user-manual/task-menu/qa-qc/feature-distribution.md)
* [Single-cell QA/QC](/partek-flow/user-manual/task-menu/qa-qc/single-cell-qa-qc.md)
* [Cell barcode QA/QC](/partek-flow/user-manual/task-menu/qa-qc/cell-barcode-qa-qc.md)

In addition to the tools listed above, many other functionalities can also be interpreted in sense of quality control. For instance, principal components analysis, hierarchical clustering (on sample level), variant detection report, and quantification report.
