Error during import_eclipse

I am repeatedly getting an error when I use the import_eclipse function, where it is 'Unable to perform assignment because the size of the left side is 3222240-by-1 and the size of the right side is 3222244-by-1.' This is related to line 54 in the MRST
eclOut2mrst script, 'G.cells.centroids(:,3) = convertFrom(init.DEPTH.values, u.length);'. I have tried several egrid/init file pairs, and each comes back with the same error where the size of the right is exactly 4 cells greater than the left.
