MapMyCorona is a blast-server for SARS CoV-2 sequences (protein or DNA) which displays the top hits in a spatial and temporal fashion.

Once displayed, you can filter the results by date or country.

MapMyCorona was developed by the Biomedical Genomics Group @ Health Data Science Unit at the BioQuant Center and Medical Faculty Heidelberg

Search sequence

A nucleotide or protein BLAST is run using as query the uploaded sequence or a specified sequence in the search box.

BLAST Options

Number of results: Maximum number of aligned sequences to keep.

Expectation value (E) threshold: Expectation value threshold for saving hits.

Percent identity (pident): Only keep hits inside this range.

Map

Displays a world map showing the geographical location of each hit, hits are clustered together depending on the zoom level, to easily visualize regions with more hits.

Clicking on a hit shows a stats summary of the BLAST result and also provides a link to the GenBank entry for that particular hit.

The area of each country with at least one hit is also colored according to the collection date, publication date or pident of its top hit

The map is responsive to all filters provided in the Options tab, and to the date range provided on top of the map.

Data explorer

Displays a table with all hits currently shown in the map.

A button is provided to download the table in csv format.

Options

Provides several filtering options on the displayed hits.

A drop down menu with a list of all countries with at least one hit, is provided to keep only hits in the selected countries.

Coloring options: options to change the color of individual hits or the country area

Score filtering: options to filter hits according to their BLAST results stats

Coloring options

Options to change the color of individual hits or the country area

Select score metric to color individual hits: select which score metric you want to use to color the individual hits

Color Area By: select option to change color of countries with at least one hit

Score filtering

Options to filter hits according to their BLAST results stats

Percent identity (pident): keep only hits between this range of pident scores

Expectation value (E): keep only hits between this range of evalue scores

bitscore: keep only hits between this range of bitscore scores
