PCA graphics and analysis of population data
of a custom Excel file (.xlsx format)


Step 1: Data input (population)

Drag and drop on the button, or select the local Excel population file to upload, whichever suits you best. You can download a valid example file if necessary to clarify ideas, or use the input file generator wizard.

Step 2: Hardy-Weinberg principle applies to your marker set

Yes (allele frequencies are used)

No (genotype frequencies are used)

Step 3: Choose type of analysis for the population data

Try to classify all individuals in the sample with the best markers.

Perform a cross-validation analysis of my population data with the best markers.

Compute bootstrap error of my population data with number of repeats (recommended number is 200).

Perform multinomial logistic regression of my population data (Step 2 applies only to shown population table, genotype frequencies are always used).

Perform genetic distance algorithm (allele and genotype versions) on my population data (Step 2 applies only to shown population table).
