A second data node of a different type than the first selected data node is chosen automatically. The second data node can selected manually using the Select data node button. 

• Click Select data node to choose the second data node you want to merge (Figure 1)

...

• Double-click the second data node to select it (Figure 2)

• Click Finish to run

A Merged counts data node is produced (Figure 3). 

The intersection of observations (cells and/or samples) from the two input matrices is included in the merged matrix. 

Once two data types have been merged, they can be split using Split matrix.

For a practical example using Merge matrices, please see our tutorial on Analyzing CITE-Seq Data, The available statistics are listed on the left panel, suppose "x₁, x₂, ..., x_n"represent an array of numbers

• Coefficient of variation (CV): Image Added s represent the standard deviation
  
  
• Geometric mean: g=Image Added
  
  
• Max: Image Added
  
  
• Mean: Image Added
  
  
  
• Median: when n is odd, median is Image Added, when n is even, median is Image Added
  
  
• Median absolute deviation: Image Added, where Image Added
  
  
• Min: Image Added
  
  
• Non zero count: number of observations that is not zero
• Q1: 25th percentile
• Q3: 75th percentile
• Range: x_max - x _min
  
  
• Standard deviation: Image Added where Image Added
  
  
• Sum: Image Added
  
  
• Variance: Image Added
