Merge Matrices

In this section, you will be able to merge data from two previously loaded genotypes matrices into a new, third one. The original matrices will remain unchanged. The new one will contain data merged from the original ones based on the merge method that has been selected (see below).

The matrix selected in the tree (1) will be the master Matrix, from which the Marker or Sample Set will be conserved. You can see the number of both from the “Parent Matrix” details (2).

Next you must choose the Matrix you want to merge data from (3).
Note: You may choose matrices that are within or beyond the current master Matrix Study.

After choosing the Matrix to be added, you must select if you want to add more Markers to the master Matrix (e.g add chromosomes) and keep the Sample Set constant, or conversely, add more Samples to the master Matrix, by keeping the Marker Set constant (e.g. add a new batch of genotyped Samples). In both cases, a description of the method will appear in the text-area (4).

The “Merge new Markers only” method entails:

  • The Sample Set from the 1st Matrix will be used in the result Matrix.
  • No new Samples from the 2nd Matrix will be added.
  • Markers from the 2nd Matrix will be merged in chromosome and position order to the Markers Set from the 1st Matrix.
  • Duplicate genotypes from the 2nd Matrix will overwrite genotypes from the 1st Matrix.

The “Merge new Samples only” method entails:

  • The MarkerSet from the 1st Matrix will be used in the result Matrix.
  • No new Markers from the 2nd Matrix will be added.
  • Samples from the 2nd Matrix will be appended to the end of the SampleSet from the 1st Matrix.
  • Duplicate genotypes from the 2nd Matrix will overwrite genotypes in the 1st Matrix.
