Metadata for Joined Clusters
About metadata for joined clusters
Purpose of metadata for joined clusters
Define which clusters for each order to join with seismic join.
For example, suppose that you have clustered two regions separately,
each up to order 3, and now you want to join those clustered regions.
You could simply have cluster i of the joined region contain cluster
i of each individual region.
However, since the number of each cluster is arbitrary, you may want to
join clusters in other ways.
For example, you may want to join the clusters at order 3 like this:
cluster 1 of the joined region contains
cluster 1 of region 1
cluster 3 of region 2
cluster 2 of the joined region contains
cluster 3 of region 1
cluster 2 of region 2
cluster 3 of the joined region contains
cluster 2 of region 1
cluster 1 of region 2
You can specify the cluster from each region that should go into each joined cluster in the joined clusters metadata file.
Note
When joining n regions, each clustered at order k, the number of ways to join those regions is kn.

Notes about metadata for joined clusters
Fields are case-sensitive and must be in the file’s first line.
In the columns “Order” and “Cluster”, the orders must start at 1 and increase with no gaps; and for each order, every cluster number from 1 to the order must be given in increasing order on its own row.
Every column after the first two (“Order” and “Cluster”) should be named after one of the individual regions.
In each region column, the number indicates which cluster from that region will be joined into the joined cluster whose order and number are given in the “Order” and “Cluster” columns. The number must be an integer between 1 and the order; and for each order, the cluster numbers may not be repeated.
