How to get a list of column names within the same cluster in MATLAB

I have a dendrogram defined by:

dm=DataMatrix(mydata,rowscell,columnnames);
cg = clustergram(dm,'Standardize','none');

I got group of clusters and I want to know which column names are within each cluster. I can look at the map, but if my column names are on the 1000s, it is not convenient to copy them manually from the graphic dendrogram.

Is there any function I can get the list of column names within each (or specific) cluster?

I think you can use the 'clusterGroup' command to get the corresponding cluster for a specific group.

For example,

cgo4group = clusterGroup(cg,4,'row')

will give the 4th cluster group. Now to get the row names you have to just execute the following command:

>> cgo4group.RowLabels
