[Qgis-user] Population genetics data depicted with QGIS

[Nicolas Cadieux]

Hi, 
Look at online documentation for the Qgis project.  There are many PDFs including a Gentle introduction to GIS. YouTube can be a good friend. 
It can all be done.  Qgis can import the txt file using the layer/add layer/add delimited text layer.  You will need to know what CRS (coordinate reference system) to set for the project (probably wgs84 epsg 4326).  Depending no the look of the final map and the type of data, you will probably use a heatmap (layer property/style/heatmap). 
Good luck( you may need it at first)! 
Write back for more info if needed.

	Dear all,  I would like to use QGIS to depict data derived from population genetic analysis. I'm working on a txt file with information relative to: - Collection sites - Latitude - Longitude - Number of individuals I would like that each collection site has got a marker (such as a circle) of different colour, and of different size according to the number of individuals that are reported for each collection site. Could you explain me how can i do it, please? I'm working in a Windows 10 laptop with QGIS 2.14.2 Essen. Thank you very much in advance. Best regards, Giulia
