Convert/Coerce DCCM .cij to basic matrix

Hi Grant Lab,

I am trying to find a way to compute the similarities of various cross-correlation matrices computed from Bio3D. For instance, I am trying to use the "dist2" function from the FlexClust package to compute the euclidean distance between two matrices but because the .cij matrix is of class "dccm" and "matrix" the following error is thrown;

Error in as(x, "matrix") : internal problem in as(): “dccm” is(object, "matrix") is TRUE, but the metadata asserts that the 'is' relation is FALSE

Do you all have another way to compute the similarites between matrices generated from trajectories? Simply trying to coerce the .cij to (as.matrix) doesn't get rid of the "dccm" class.
