**What it does**

variable VirusAMPlicons (varVAMP) is a tool to design primers for highly diverse viruses. The input is an alignment of your viral (full-genome) sequences.

For a lot of virus genera it is difficult to design pan-specific primers. varVAMP solves this by introducing ambiguous characters into primers and minimizes mismatches at the 3' end. Primers might not work for some sequences of your input alignment but should recognize the large majority.

varVAMP can be run in three different **modes**:

* SINGLE: varVAMP searches for the very best primers and reports back non-overlapping amplicons which can be used for PCR-based screening approaches.
* TILED: varVAMP uses a graph based approach to design overlapping (tiled) amplicons that together cover the entire viral genome. This designs amplicons that are suitable for Oxford Nanopore or Illumina based full-genome sequencing.
* QPCR: varVAMP searches for small amplicons with an optimized internal probe (TaqMan). It minimizes temperature differences between the primers and checks for amplicon secondary structures.

Algorithmic parameters:

These are explained very well on the `How varVAMP works <https://github.com/jonas-fuchs/varVAMP/blob/master/docs/how_varvamp_works.md>`__ page of the varVAMP documentation.

Outputs:

This tool can produce lots of informative output and the different modes come with what we hope are reasonable default choices.

The most important output, however, is the **Analysis Log**, which will always be generated and contains essential information about what parameters where used by varVAMP during the run and about intermediate results. You should always check this file. Together with the tool's standard output and error streams, it is the place to spot issues with your analysis and to start debugging them.

.. class:: infomark

Testing with a new alignment/analysis:

As a first check whether a new alignment of viral sequences can be used with specific settings of the tool, it may help to disable all configurable outputs, which will leave you with only the Analysis Log. This will be enough to see if there are any errors with the combination of alignment and settings, and whether you are on a roughly correct track (varVAMP reports some primers, for example). This way, you're not flooding your analysis history with lots of likely useless datasets, and once you've fixed potential issues you can add back more outputs and rerun the analysis.
