But what is a dendrogram? And what is UPGMA? And why should you use this software?

A dendrogram is a diagram that shows the hierarchical relationship between different data points or groups. It consists of U-shaped lines that connect data points in a tree-like structure. The length of the lines represents the distance or dissimilarity between two data points or groups.

A dendrogram can help you visualize and analyze your data in various fields, such as biology, ecology, sociology, psychology, marketing, etc. For example, you can use a dendrogram to cluster genes based on their expression patterns, species based on their genetic similarity, customers based on their preferences, etc.

UPGMA stands for Unweighted Pair Group Method with Arithmetic Mean. It is a simple and popular method for creating dendrograms from a distance matrix. It works by finding the two closest data points or groups and joining them in a cluster. Then it calculates the average distance between each remaining data point or group and the new cluster. This process is repeated until all data points or groups are merged into one.

WPGMA stands for Weighted Pair Group Method with Arithmetic Mean. It is a similar method to UPGMA, but it assigns different weights to the distances between data points or groups based on the number of elements in each group. This makes it more sensitive to the shape of the clusters.

## How to Use Upgma Dendrogram Software Free 17

To use Upgma Dendrogram Software Free 17, you need to follow these five steps:

Choose your input data

Choose your similarity index or distance coefficient

Choose your clustering method

Choose your additional options

Submit your data and view your results

We will explain each step in detail below.

### Step 1: Choose Your Input Data

The first step is to choose your input data. You have three options for input data:

Sets of variables: This option allows you to enter sets of variables that represent different data points or groups. For example, if you want to cluster genes based on their expression levels in different samples, you can enter the gene names as rows and the sample names as columns. The values in each cell represent the expression level of each gene in each sample.

Similarity matrix: This option allows you to enter a matrix that represents the similarity between different data points or groups. For example, if you want to cluster species based on their genetic similarity, you can enter the species names as rows and columns. The values in each cell represent the similarity between each pair of species.

Distance matrix: This option allows you to enter a matrix that represents the distance between different data points or groups. For example, if you want to cluster customers based on their preferences, you can enter the customer names as rows and columns. The values in each cell represent the distance between each pair of customers.

You can upload your input data from a file or copy and paste it from a spreadsheet. The file format should be CSV (comma-separated values) or TSV (tab-separated values). The spreadsheet format should be Excel (.xls or .xlsx) or Google Sheets (.gsheet).

You can also enter your input data manually by typing it in the text box. The format should be as follows:

The first row should contain the column names (optional)

The first column should contain the row names (optional)

The values should be separated by commas or tabs

The values should be numeric (except for row and column names)

The values should be positive (except for distance matrix)

The matrix should be square (same number of rows and columns)

Here are some examples of input data:

ABCDGene10.50.70.20.4

Gene20.60.80.30.5

Gene30.40.60.10.3

Gene40.70.90.40.6

This is an example of a set of variables, where the rows are genes and the columns are samples. The values are expression levels.

Dog0.751.000.600.30

Bird0.500.601.000.40

Fish0.250.300.401.00

This is an example of a similarity matrix, where the rows and columns are species. The values are similarity scores.

Charlie4.003.000.002.00

Dave6.005.002.000.00

This is an example of a distance matrix, where the rows and columns are customers. The values are preference distances.

### Step 2: Choose Your Similarity Index or Distance Coefficient

The second step is to choose your similarity index or distance coefficient. This is the measure that determines how similar or dissimilar two data points or groups are.

If you use sets of variables as your input data, you need to choose a similarity index or a distance coefficient. A similarity index is a value between 0 and 1 that indicates how similar two data points or groups are. A distance coefficient is a value that indicates how far apart two data points or groups are.

If you use similarity matrix or distance matrix as your input data, you don't need to choose a similarity index or a distance coefficient, because they are already provided in your input data.

You have the following options for similarity index or distance coefficient:

Pearson correlation coefficient: This is a measure of the linear relationship between two sets of variables. It ranges from -1 to 1, where -1 means perfect negative correlation, 0 means no correlation, and 1 means perfect positive correlation.

Jaccard index: This is a measure of the overlap between two sets of variables. It ranges from 0 to 1, where 0 means no overlap and 1 means complete overlap.

Dice coefficient: This is a measure of the similarity between two sets of variables based on the number of common elements. It ranges from 0 to 1, where 0 means no common elements and 1 means all elements are common.

Euclidean distance: This is a measure of the straight-line distance between two sets of variables in a multidimensional space. It can be any positive value, where 0 means identical sets and higher values mean more dissimilar sets.

Manhattan distance: This is a measure of the sum of the absolute differences between two sets of variables in a multidimensional space. It can be any positive value, where 0 means identical sets and higher values mean more dissimilar sets.

MSD: This stands for Mean Squared Deviation. It is a measure of the average of the squared differences between two sets of variables. It can be any positive value, where 0 means identical sets and higher values mean more dissimilar sets.

RMSD: This stands for Root Mean Squared Deviation. It is a measure of the square root of the average of the squared differences between two sets of variables. It can be any positive value, where 0 means identical sets and higher values mean more dissimilar sets.

You can also customize your own formula for similarity index or distance coefficient by entering it in the text box below the options. You can use the following symbols:

x and y for the values of each variable in each set

n for the number of variables in each set

+ - * / ^ for arithmetic operations

() for parentheses

sqrt() for square root function

abs() for absolute value function

sum() for summation function

mean() for mean function

var() for variance function

sd() for standard deviation function

cov() for covariance function

cor() for correlation function

Here are some examples of custom formulas:

(sum(x*y)/n)/(sqrt(sum(x^2)/n)*sqrt(sum(y^2)/n)) for Pearson correlation coefficient

(sum(x*y)/n)/(sum(x/n)+sum(y/n)-sum(x*y)/n) for Jaccard index

(2*sum(x*y)/n)/(sum(x/n)+sum(y/n)) for Dice coefficient sqrt(sum((x-y)^2)/n) for Euclidean distance

sum(abs(x-y)/n) for Manhattan distance

sum((x-y)^2)/n for MSD

sqrt(sum((x-y)^2)/n) for RMSD

You can choose the best similarity index or distance coefficient for your data based on the type and distribution of your variables, the purpose and goal of your analysis, and the assumptions and limitations of each measure.

### Step 3: Choose Your Clustering Method

The third step is to choose your clustering method. This is the algorithm that determines how to group your data points or groups into clusters based on their similarity or distance.

You have two options for clustering method: UPGMA or WPGMA. Both methods are based on the same principle, but they differ in how they calculate the distance between clusters.

UPGMA stands for Unweighted Pair Group Method with Arithmetic Mean. It calculates the distance between two clusters as the average of the distances between all pairs of data points or groups in each cluster. It assumes that the rate of change is constant across all branches of the dendrogram.

WPGMA stands for Weighted Pair Group Method with Arithmetic Mean. It calculates the distance between two clusters as the weighted average of the distances between all pairs of data points or groups in each cluster, where the weights are proportional to the number of elements in each cluster. It assumes that the rate of change is proportional to the branch length of the dendrogram.

You can choose the best clustering method for your data based on the type and distribution of your variables, the purpose and goal of your analysis, and the assumptions and limitations of each method.

### Step 4: Choose Your Additional Options

The fourth step is to choose your additional options. These are optional features that can help you improve your data analysis and visualization.

You have the following options for additional options:

Normalize data: This option allows you to normalize your data by subtracting the mean and dividing by the standard deviation of each variable. This can help you reduce the effect of outliers and scale differences among variables.

Transform r values: This option allows you to transform your similarity index values (r) into distance coefficient values (d) by using one of these formulas: d = 1 - r, d = sqrt(1 - r^2), d = -log(r). This can help you convert correlation-based measures into distance-based measures.

Generate bootstrap replicates: This option allows you to generate bootstrap replicates of your data by resampling with replacement. This can help you assess the reliability and stability of your clusters by calculating confidence intervals or p-values.

Omit rows with identical values or similarity of 1: This option allows you to omit rows that have identical values or similarity of 1 with another row. This can help you reduce redundancy and noise in your data.

You can choose the best additional options for your data based on the type and distribution of your variables, the purpose and goal of your analysis, and the advantages and disadvantages of each option.

### Step 5: Submit Your Data and View Your Results

The fifth and final step is to submit your data and view your results. You just need to click on the "Submit" button at the bottom of the page and wait for a few seconds.

You will see three output formats: dendrogram image, Newick format, and CSV format. You can view, download, or export any of these formats as you wish.

The dendrogram image is a graphical representation of your clusters in a tree-like structure. You can adjust the size, color, font, and labels of your dendrogram by using the options on the right side of the image. You can also zoom in or out by using your mouse wheel or trackpad.

The Newick format is a text representation of your clusters in a nested parentheses notation. You can use this format to import your dendrogram into other software or tools that support Newick format, such as PhyloDraw, FigTree, or R.

The CSV format is a table representation of your clusters in a comma-separated values format. You can use this format to export your dendrogram into a spreadsheet or a database that supports CSV format, such as Excel, Google Sheets, or SQL.

You can interpret and analyze your results by looking at the shape, length, and position of the branches and nodes of the dendrogram. You can also compare the results of different input data, similarity index, distance coefficient, clustering method, and additional options to see how they affect your clusters.
