# Parameters
## Type
Defines the measure of correlation that should be calculated between the selected columns (default: Pearson correlation). It can be selected from a list of correlation coefficients:
- Log2(Absence-presence enrichment factor)
- Absence-presence -Log10(p-value)
- Numbers of valid pairs
- Valid pairs percentage
- Pearson correlation
- -Log10(Pearson p-value)
- -Log10(Pearson p-value) \[correlation\]
- -Log10(Pearson p-value) \[anti-correlation\]
- R squared
- Spearman rank correlation
- -Log10(Spearman p-value)
- -Log10(Spearman p-value) \[correlation\]
- -Log10(Spearman p-value) \[anti-correlation\]
- Kendall rank correlation
- Distance correlation
- Mutual information
- Euclidean distance
- Manhattan distance
- Maximum distance
## Rows
Selected expression/numerical columns that will be the rows of the generated correlation matrix (default: all expression columns are selected).
## Columns
Selected expression/numerical columns that will be the columns of the generated correlation matrix (default: all expression columns are selected).
